TIG Welding Aluminum 10 Equipment Pieces for Good Weld

TIG welding aluminum can be hard, particularly for beginners. Here are some helpful TIG welding aluminum tips and equipment to help you create quality weld jobs.

Know TIG welding aluminum tips

TIG welding aluminum can be a challenge, especially those with little Tig welding aluminumor no experience in welding aluminum, or even welding in general. This process involves getting two pieces of aluminum to stick together without breaking, shriveling, warping or cracking. Here are some helpful tig welding aluminum tips to help you learn how to weld aluminum faster than you would have otherwise. Here is a list of the equipment that you need.

1. TIG welder

Many sources say a TIG welder is the best method for welding aluminum. TIG welders are quite expensive and it can be hard to justify even the lowest quality units unless you’re making money with it. The most expensive units come with features that make doing high quality welds on aluminum possible. There are also bottom-of-the-line welders that is great for farmers or hobbyists. Know that adequate welds can still be made with a cheaper machine. But with a more expensive one, you get more amperage, water cooling, square wave AC, frequency adjustment and adjustment of positive to negative current for better penetration and cleaning.

2. Good welding gloves

Invest in high quality welding gloves; these will go a long way. Using those cheap ones will only lead to painful blisters.

3. Good welding helmet

Experts recommend that you get the gold tinted auto-darkening helments. although they can be expensive. Of course, you can still use those standard welding helmets; just make sure that you use them right.

4. Argon gas

Mixes will not work for aluminum, expect for an argon-helium mix. Never take the tank from MIG welding aluminum to use on your TIG welder because it will not work at all. You will only make a bunch of burnt soot and metal.

5. Aluminum welding rod

There are several recommended welding rods; you can ask an expert for advise. Make sure that you know which rod to use for which alloys as well as a ton of excellent aluminum and metalworking information, along with tig welding aluminum settings. You might ask how to tell one alloy from another, but you will not do any mission critical welding, so you do not have to worry about it.

6. Dedicated stainless steel

Use this stainless steel brush only for aluminum. As much as possible, label it with ‘aluminum’ so it will not get used for anything else.

7. Metal bench

If you do not have one, experts suggest that you get yourself one. Stopping your weld to put out a fire can be a big hassle. This can happen to you all the time, especially if you are still getting started with welding.

8. Squirt bottle with water

This is not for cooling the work, it is for putting out small fires that are not big enough to use a fire extinguisher on. Cooling aluminum quickly can cause it to crack in or near the weld.

9. Fire extinguisher

This might not be such as bad idea if you do not want to get fired for burning down the shop.

10. Heavy long sleeve cotton work shirt

This one is very important. TIG welding gives more UV radiation than any other welding process

Merely using a T-shirt or any other thin clothing will end up with you being painfully burned with peeling skin and blisters. It only takes just a few minutes to give you some serious burns.

11. Clamps or vise grips Get these or whatever you’ll use to hold your work in place

Also get some bars or blocks or copper or aluminum to use as heat sinks.

You do not have to make TIG welding aluminum hard and hazardous for you. Follow the simple tips above and you should be on your way to creating quality welds. If you are still unsure of your welding skills, contact a reputable, certified TIG welder or welding company in your area to do your welding projects for you.

Orbital Welding Procedure in Food and Drugs Industry

A great procedure for sterile or clean conditions, orbital welding procedure is now being adopted by many industries today. Learn how orbital welding programs are used in the food, beverage and pharmaceutical industry.

Orbital welding procedure for food

The orbital welding procedure has shown to be very effective in joiningOrbital welding procedure stainless steel tubing for systems where the products flowing through them has to be maintained in a sterile or clean condition. The ability to make smooth, crevice-free welds that maintain consistency and uniformity for numerous joints have made orbital welding technology the accepted joining technology for pharmeceutical in the United States. Crevice-free welds are important for controlling the growth of microorganisms in hygeinic pipe systems. The food and dairy industries in the country, which has been slow to adopting orbital welding, have shown a growing awareness during the previous years that the joining technology used to fabricate sanity piping systems is essential to achieving and maintaining sterilizability and cleanliness, and they are taking steps to improving the hygienic condition of their systems.

Orbital Welding Procedure for the Biopharmaceutical Industry

Orbital welding has been used for water for injection (WFI) and deionized (DI) piping systems throughout the pharmaceutical industry since the 70s. One example is a facility in Brazil that used orbital welding to join piping systems for WFI, hot DI water, cold water and compressed air at a high-tech art R&D and production facility for the production and manufacture of vaccines. Orbital welding is mostly used for installing process equipment on-site like the larger fermented for antigen production installed in a clear room at the facility. Welding standards in this facility had to meet the exact criteria needed for export of the vaccines to countries outside Brazil.

Another common orbital welding application is the installation of skid-mounted equipment. Biopharmaceutical equipment is mostly installed on skids with connecting piping and associated equipment that are fabricated off-site. This gives some amount of flexibility in location the equipment on-site and facilities installation. One example is orbital welding of boiler tubes used for joining the important pipes that gives gases to the bioreactor on the bio-reactor skids made by biotechnology facilities.

Orbital Welding Procedure in the Food Industry

Many of the major food industry suppliers have started using orbital welding. For example, Kraft Foods have bought orbital welding systems for many of its plants in many parts of the United States. They find it practical to have an orbital welder on-site for maintenance jobs and small installations that they can do themselves without the need to hire a contractor. Procter and Gamble installed piping systems. The company has specified that orbital welding should be used in their new construction if practical. Many fabricators have also been uisng orbital welding to manufacture fittings and equipment for food and dairy applications for at least a decade.

The North Atlantic Free Trade Agreement has shown interest in orbital welding in Mexico to meet the new requirements for export in Canada and United States. More food industry end users in Mexico now specify orbital welding. One company uses orbital welding to weld 316L  tubing in different sizes for pulp, fruit juice and dairy application. In India where skilled manual welders are scarce, one company orbitally welded the stainless steel piping systems in a cheese plant to process cheese slices for McDonald’s.

Orbital Welding Procedure in the Beer Industry

From the beginning, breweries have recognized the need control microbial growth in their process piping. One particular brewery in California that orbital welded around 11 miles of four and six-inch schedule pipe was one of the first orbital welding applications. Orbital welding is particularly important for making draft and cold filtered beer that are not pasteurized. Many of the major breweries in the United States and several in Latin America countries like Brazil, Argentina, Mexico and Nicaragua have successfully done orbital welding installations. And, to date, more breweries are replacing their manual welds with orbital welds.

All these is a proof of a growing interest in improving standards in the dairy, food, beverage and the pharmaceutical industry in the United States, Latin America, and in other countries as well. If end-users examine the cost-benefit ratios of new technologies, they discover that the orbital welding programs offers higher quality welds with better corrosion resistance at a reasonable cost in many applications of higher productivity. As these industries continue to improve on their fabrication practices, using orbital engineering is at the forefront.

A Beginners’ Guide: GTAW Welding Techniques and Tips

Any welder should know GTAW welding techniques and tips to ensure a good weld. Here is a guide on TIG welding for beginners to make the process quick and safe for everyone.

GTAW welding techniques and tips

Before the GTAW welding process starts, all grease, oil, dirt, rust andGtaw welding techniques other contaminants should be removed from the areas to be welded. You can do this by the use of liquid or vapor cleansers of by mechanical means. Striking the arc can be done by momentarily touching the electrode to the work and quickly withdrawing it; using a apparatus to cause a spark to jump from the electrode to the work; and using an apparatus that initiates and maintains a small pilot arc, giving an ionized path for the main arc.

GTAW Welding: High Frequency Arc Stabilizers

High frequency arc stabilizers are needed when alternating current is used. They give the kind of arc starting described above. High frequency arc initiation occurs when a high-voltage, high-frequency signal is superimposed on the welding circuit. High voltage ionizes the shielding gas between the work piece and electrode, making the gas conducive so it initiates the arc. Inert gases are not conducive until they are ionized. For DC welding, the high frequency voltage is cut off after arc initiation. With AC welding, however, it mostly remains on during the welding, especially when welding aluminum.

GTAW Welding: Operating Variables

Briefly summarized, for TIG welding for beginners, the major welding process operating variables are: welding current, voltage, and power source characteristics; electrode composition, shape and current carrying capacity; shielding gas (welding-grade helium, argon or mixtures of both); filler metals that are generally the same to the metal being joined and suitable for the intended service

GTAW Welding: Techniques and Tips

1. Check the recommended gas flow based on the selected nozzle and the metal size. Adjust the gas welding machine to the suggested kind of amperage and current for the welding process being performed.

2. Turn the welder on and locate the foot control. Place the control in an area that is most comfortable. Press the foot control and strike the arc. Check your TIG welding manual for more information.

3. Once a puddle is formed, add the filler rod to the leading edge. To reduce chances of contaminating the tungsten, move the TIG welding torch to the back of the puddle once the filler rod is added.

4. Clean all metal surfaces and joints to be welded with a mechanical (grinding, scraping or bruising with a wire brush) or chemical process. Take note that the wire brush should be made of the same material as the material being welded (except for aluminum which can be cleaned using a stainless steel brush. Chemical solvents range from harsh chemicals like acetone and the light cleaning properties of alcohol.

5. Know the metal size. Except for aluminum and magnesium, the welding process should not be used with metals over 1/4 inch. Metals that are under 3/16 inch may not require edge prep. Metals that have a thickness of more than 3/16 inches require machined or ground edges to help bead penetration.

GTAW Welding: How to Stop Welding

Welding is stopped by shutting the current off with foot-or-hand controlled switches that allow the welder to start, adjust, and stop the welding current. They also allow the welder to control the welding current to get good fusion and penetration. TIG welding can also be stopped by quickly withdrawing the electrode from the current, although this can disturb the gas shielding and expose the weld pool and tungsten to oxidation. Shielding gas has to stay on for several seconds to keep the molten puddle, filler rod ad tungsten electrode from being contaminated.

GTAW Welding: Filler Metals

In the TIG welding process, the base metal thickness and joint design determine whether or not the filler metal has to be added to the joints. If the filler metal is added during manual welding, it is applied by feeding the welding rod manually into the pool of molten metal ahead of the arc, but to one side of the center line.

Knowing the right GTAW welding techniques and tips is important before you start your project. However, this can be too confusing for those who have little to no experience. In this case, you should be better off hiring a certified welder and allow him to do the job for you. Aside from ensuring a safe and effective welding job, you should have the peace of mind that the end results are of high quality, one that will last for a very long time.

TIG Welding Process: Know the When, Where and Why

Giving the highest weld quality, the TIG welding process is one of the most versatile when it comes to the material to be used and its position. When it comes to weld versatility and integrity, this process is the best choice.

TIG welding process gives the highest quality

Of all arc welding processes, it is the tungstel inert gas orwelding TIG welding process that is capable of achieving the highest quality welds. It is also the most versatile when it comes to what can be welded and the position of the welds. Only metal inert gas (MIG) welding comes close, but TIG still comes out on top for weld versatility and integrity. Read on as we go through the basics of this process, along with some of its most common applications.

But just like in many industrial processes, quality comes at the expense of time. TIG is generally slower compared to manual metal arc (MMA), but where weld is important, production engineers are prepared to work with the additional process time. However, there are some cases where a welded joint will use TIG along with MIG welding. For instance, when joining pipes for offshore applications, TIG can be specified for the root weld and then MIG for the subsequent runs. This gives high integrity, which is important at the root, along with the quality and speed of MIG for the rest of the joint.

TIG welding is considered to be a very versatile process. The TIG welding process parameters can practically be used with any weldable metals, including different metals with thickness from half a millimeter onward. TIG welding machines are mostly available in current ratings between 150A and 350A and are able to operate at currents as low as 3A for a 150A machine. Also, TIG machines can be used for MMA welding and brazing, which should aid in improving the return on an investment in a TIG equipment.

The most commonly used gas for the TIG welding process for all materials is pure argon

A combination of argon and helium when welding copper and aluminum because added heat is needed fo helium. This the opposite of the MIG welding process, where there is a specific gas or gas mixture for a certain material to be welded. However, TIG operatives have to aware that the right tungsten electrode has to be used. Otherwise, problems can be encountered in striking the arc and maintaining a stable arc. TIG can be done with or without a filler wire, just like oxyacetylene gas welding.

One of the many advantages of TIG welding is that the wold only processes high integrity and give an aesthetic surface finish

Consequently, welds can mostly be left as is without any need for grinding. This is advantageous when it comes to time saved, and it avoids problems with grinding in site, like dust and noise. Depending on the TIG welding material used, the operative can have control over most of the weld parameters, therefore optimizing the weld quality. Modern TIG power sources are lighter and more portable than traditional unis, so on-site TIG welding is commonplace.

The usual applications for TIG welding include architectural stainless steel fabrications like balustrades

More unconventional applications include jewelry, dentistry and titanium. For low-current and fine work applications, TIG is increasingly being used as a more versatile alternative to micro-plasma welding. Skilled operatives are able to produce excellent results with TIG welding, although automation can be economically used on straight arcs and runs to avoid variances associated with operative skill levels or fatigue.

In welding applications, the most costly element is mostly the welding operative. Therefore, it is a relatively simple matter to determine the savings from automating a TIG welding process and the expected payback period that can be expected when automating a TIG welding operation. Among all welding process, TIG requires the highest skill level, primarily because it is a two-handed process, with one hand required for the filler wire and the other for the TIG torch. Even autogenous welding requires good skills.

If a fabricator is considering investing in TIG welding, there are many training providers available nationwide. They can train an operative from scratch or retrain an operative who has used MIG, MMA or gas welding. Interestingly, welders who has had experience with gas welding mostly find it easiest to make the transition because they are used to hand feeding a filler wire. TIG welding is based on a simple concept, but the process is still continually being developed.

Generally speaking, TIG welding is best for niche applications where weld integrity and aesthetics are more important than speed. With this said TIG welding is also the most versatile of all welding processes in terms of the materials is can weld, the material thickness, the option to use a filler wire or not, and the way it can be used for welding of any position.

TIG Welding Techniques For The Best Welds

If you are learning TIG welding techniques or are just trying to be a TIG welder, the last thing that should come up to speed is the hand feeding the rod. In kindergarten, we all learned how to hold a big crayon and this is not too different from holding a TIG torch. If the hand that feeds the filler rod is a bit of a slow learner, a really thin glove helps. If you’re having problems feeling the wire, try mechanical gloves or woven cotton gloves. Below are more techniques and tips to help you out.

TIG Welding Techniques

Choose the Right-Size TIG Welding Rod

TIG weldingFor sheet metal up to 1/8-inch thick, do not use a welding rod bigger than the thickness of the metal you’re welding. The amperage is low and the weld puddle needs to be small to prevent blowing a hole. When you dip the rod into the puddle, the rod sucks the heat from the puddle, making it hard to maintain a consistent size bead. It is best that beginners should not practice with thin metal.

TIG Torch Handle Should be 10 Degrees or Less

Ideally, the torch angle should only measure around 10 degrees or less. If you have too much torch angle, the heat will be deflected and the rod will melt even before you get into the puddle. This will cause the rod to ball up and blog into the puddle. You want to slip the filler rod into the puddle so you get a consistent bead. Exceptions to this include when you’re using a lay wire technique and are leaning the torch back while you walk the cup.

Never Let a Ball Form at the Rod End

If this happens, you are doing something wrong. It might be because, you are looking an arc that’s too long, too much torch angle, bad filler rod angle, not enough amperage or a combination of these things. The most common of these among newbies are using too much torch angle and too long an arc. A long arc means heat is not concentrated and you get this big heated arc plume like you would get with a gas welding torch.

TIG Welding Process

Thoriated Tungsten Electrodes are Radioactive

Many people say 2% thoriated tungsten electrodes are mildly radioactive, but 2% lanthanated electrodes are just as good as 2% thoriated. So if you are scared if thoriated tungsten but you are even more scared of crappy electrodes that don’t work as well, use 2% lanthanated (they are colored blue). Take note that the blue ones are not brittle like 2% thoriated electrodes. Also, they splinter if you try to break them or snip with dykes.

Use the Smallest Tungsten for the Job

Use the smallest tungsten within reason. Another way of saying this is to not just use 1/8-inch electrodes for everything. There are jobs where this small electrode is great. But if you are welding on the edge of a 0.3-inch turbine blade, a 0.4-inch electrode should be good enough to handle the 15 amps and give much better starts compared to a 1/16-inch electrode.

Get A Certified TIG Welder

While you can very well do MIG welding or TIG welding process on your own, perhaps it would be a better idea to pass on complicated weld jobs over to a person or a company that’s more experienced. Contact a certified TIG welder so you can get started.

A Complete Guide To Buying Orbital Welding Equipment

Orbital welding is an economical and viable method for connecting stainless steel tubing, particularly in applications in which high performance, maximum leak integrity, ultra cleanliness, and vibration resistance is of utmost importance. It is not a surprise, then, that more and more companies are opting for this system to get their jobs done. If you are considering orbital welding, it is important to remember that not all systems are alike. You can take steps to make sure that the selection of equipment that will meet your specific needs while maximizing efficiency and productivity.

Choose The Right Orbital Welding System

Remember that price is not the primary determinant of whether an orbital weldingwelding system is right for your application. There is not much difference in price among orbital welding systems, but the capabilities of every system can be very different. An orbital welding system is a capital investment. Determine if the system is designed in a manner that allows for modifications, like the acceptance of new software. It is important that you study what every system can offer; you would not want to invest on something that renders itself obsolete after just a few years. For one, you need to make sure that that you get systems with the best features, or those that suit your needs best. Below are some capabilities to consider when getting orbital welding equipment sale:

Factors To Consider When Buying Orbital Welding Equipment

• Mobility: There are some systems that are compact and lightweight, while others are bulkier. If you need to move into tight spaces or travel, go for the lighter weight model, so you can quickly and easily move from one job to another.

• Power: Consider input and output capacities: Some systems output 100 amps from a 110 V/20 amp line. Others require a 110 V/30 amp line to create the same 100 amp output. If you use traditional power sources and want to avoid upgrades, get systems that can be powered by 110 V/20 amp lines.

• Weld head and fixturing flexibility: In orbital welding tubes to fittings or tube to valves or similar combinations, you want a system in which the weld heads and fixtures can easily be adapted for a quick setup change. There are some fixtures that can be taken apart and reconfigured to accommodate a range of weld setups. Detachable fixtures and remote controls allow joints to be pre-positioned and allow orbital welding to be done in tight places.

• Programming: There is a program or procedure that should be developed for every weld type. These programs need to be adjusted and stored to accommodate variations in material heats. If your application at any time requires extensive weld programs, get a system with technology that makes the programming process simpler. A system that is user-friendly can allow programs to be built in an accurate and consistent manner via auto-generation capabilities. These reduce human error and shave up to 90 minutes off the time devoted to building programs.

• Documentation: The process of documentation can be time consuming and expensive. Detailed weld logs should be kept, and the information usually is entered in databases. Get a system that automatically logs and stores data for easy transfer and retrieval to databases. This reduces the cost and time of documentation.

• Data management: Data management features enhance greatly the ability to track trends, calculate costs per weld and review production rates. This can go a long way to improving bid accuracy, lowering costs and improving efficiency.

Maintenance and serving programs are just as important as the equipment itself. If something should go wrong, you would be want to be forced into huge downtime because of the responsiveness issues of the manufacturer. See if a supplier has a local network of service providers, giving easy access to replacement equipment and maintenance. See if the manufacturer gives backup equipment for free. Training, which improve orbital welding protocol and play a role in getting weld consistency, is another important consideration. Training programs from equipment supplies can vary. Some focus on how to give genuine orbital welding courses, while others on learning the usage of the controls of a particular type of equipment.

Go For Orbital Welding

In conclusion, make sure that you do your homework before and during the selection process. If you focus your sights on these areas, you can maximize performance and achieve high quality, repeatable welds on a consistent basis. Choosing pro fusion welding equipment can have a direct effect on whether compliance is achieved in the most efficient, productive and cost-efficient manner. Most importantly, ensure that you choose a reputable company or manufacturer from where you will buy your equipment.

TIG Welding: Tips To Properly Weld Sheet Metal

DCWI_logo1-300x151TIG welding has so many applications; one of the most common is in the aviation and airline industries. In such work, TIG welders usually use weld sheet metal. If you are welding sheet metal for aircraft applications, or for any other that you can think of, consider the following TIG welding tips to ensure that you get the high quality work that is needed.

Just Follow These Simple TIG Welding Tips

Follow rule of thumb – To estimate required heat output, use the rule 1 amp per 1 thousandths inch of carbon steel thickness. Stainless steel and other nickel-based metals need less heat because nickel is a poor heat conductor. For magnesium and aluminum, which are excellent conductors, increase heat output slightly.

Chill out – Use copper chill bats with argon ports. Both the copper and gas draw heat away from the weld area. While it’s okay to use a copper shoe attached to a steel structure, make sure you configure the bar so the copper touches the well-meant. Take care that you do not put copper in direct content with cobalt allows as this may cause issues in high-temperature applications.

Cover your backside – When welding sheet metal, treat most applications like titanium. Titanium always needs shielding the backside of the weld to prevent oxidation. In thin applications, shielding gas on the backside of the weld reduces heat output. It also improves weld quality by eliminating metal surface imperfections that could potentially be a source of cracking high fatigue applications.

Love the back-step – The standard practice in TIG welding involves pushing the weld puddle in one continuous direction for the entire length of the weld. With back-stepping, the welder breaks up the seam in parts to dissipate the heat. Do not confuse the back-step method, which is a planned series of steps along a single joint with the randomness of skip welding.

Super size it – Other sheet metal applications usually require a size #7 TIG cup. For welding sheet metal in aerospace applications, #15 cup or larger is required. A large cup gives better gas coverage of the weld puddle and heat affected zone, which reduces total heat input and improving bead quality. It should also improve bead appearance.

Lens crafter – Always use a TIG torch with a gas lens. The lens smoothens the gas flow and prevents turbulence, which widens the area of gas coverage. If needed, it allows increased electrode extension beyond the cup. Extending the electrode will allow it to reach into the corners and give better visibility of the weld area.

Mind The Gap  Of  Your TIG Welding

– To do maintenance on some parts, you should cut them to gain access and re-weld the part while maintaining the original dimensions of the part. All parts shrink when welded, so make sure that you plan ahead. Good fixturing, R&D work and experience can give an indication of how to pre-gap a part before welding.

To the point – Electricity likes to come off a point. Nothing focuses an arc more than needle-sharp tungsten. Sharp tungsten directs the heat where you want it. Also, you do not weld with contaminated tungsten; it is a recipe for rework. Having a standard on lanthenated electrodes for all your applications should help.

Always Look For Extensive TIG Welding Experience

If you are looking to get TIG welding done for aerospace application, or for whatever industry, but you have limited TIG welding experience, it would be best that you contact a certified welding company to do it for you.

Most Common Applications Of Orbital Welding

Orbital WeldingThe process of orbital welding got its name from the fact that an electrode rotates around the stationary product that is being welded. As with tungsten inert gas welding (or TIG welding), an electric arc is produced between a non-consumable tungsten electrode and the metal that is welded. The weld pool is made up of the base metals themselves. Orbital welding is especially valuable in applying quality welds to tubes and pipes, as well as other difficult or complicated welds.

Since its birth in the 1960s, orbital weld systems have since then evolved to cater to the growing needs and technologies through time. Today, they have computer programs that can store welding parameters in memory. This basically allows the skills of a certified welder to be programmed into the system, allowing the on-going production of identical welds, and virtually eliminating welder error and defects.

The commonly used 300-series stainless steels offer a high degree of weld ability using orbital equipment, except for types 303/303SE, which allow for machining ease. The 400-series stainless steels, while weldable, may require post-weld heat treatment. Welders adjust the orbital-welding setup to accommodate for potential differences among material heats.

Other Applications Of Orbital Welding

• Aerospace – The aerospace industry was the first to use automated orbital welding. The high pressure hydraulic systems of a single aircraft can contain more than 1,500 welded joints.

• Boiler-tubes – Boiler-tube installation and maintenance offer perfect scenario for orbital welding. Compact orbital weld heads can be placed in between rows of boiler tubes.

• Food, dairy and beverage industries – This sector of the industry requires consistent full-penetration welds on all weld joints. For maximum piping system efficiency, the tubing and pipe welds must be as smooth as possible. Any defect or incomplete weld joint can trap fluid inside the pipe or tubing, harboring bacteria.

• Nuclear piping – The nuclear power industries severe operating environment, and specifications for high quality welds, has long been a user of orbital welding.

• Offshore applications – Submerged hydraulic systems welded with orbital equipment offer superior corrosion resistance and mechanical properties.

• Pharmaceutical industry – Pharmaceutical process lines and piping systems require high quality welds to ensure a source of water from the tubes is uncontaminated by rust, bacteria and other contaminants. Orbital welding ensures full-penetration welds with no overheating that can affect the corrosion resistance in the welded joint.

• Semiconductor industry – The semiconductor industry requires piping systems with very smooth internal surface finish to prevent contaminant build-up on the tubing wall or weld joints. A build-up of particulate, moisture or contaminant could increase and ruin the batch process.

• Tube fittings, valves and regulators – Hydraulic lines, oil and natural gas storage, delivery systems, and medical gas systems all require consistent quality and defect-free welds. Orbitally welded systems give the means to ensure high productivity of welding and optimal weld quality.

Find Certified Orbital Welding

If you are looking to weld parts for any of the industries listed above – or for any other not found above – look for a certified orbital welding company to do it for you. Ensure that they have certified orbital welders to ensure quality work.

About Welding And Its Different Types


weldingWelding is the most widely practiced way of joining metals together because of the efficiency and economy of the process. It has been estimated that about 50% of the Gross National Product of the United States arises from the activities that are, in some form or another, related, perhaps remotely, to welding. As an example, farming may appear to have nothing to do with welding, but the equipment the farmer uses to grow and harvest crops will have used welding in their manufacturing process.

Until the advent of the 20th century, welding was confined to blacksmith shops where two pieces of metal were heated to very high temperatures in a forge and then hammered together until the joining occurred. This is what is called forge welding. With the introduction of electricity into industrial processes, welding become both easier and quicker, and also more economical.

There are four types of welding techniques commonly used

•    Arc Welding – This is the most basic welding technique where the parts to be joined together are brought into contact with strong electrical current and heated. The molten parts are then joined together to form a weld. This is the low technology end of welding in its cheapest and least sophisticated form.

•    Gas Welding – This is generally used for repair work, particularly in the case of hollow items like pipes and tubes. Hot gas is forced onto the surfaces to be welded. This procedure requires the parts to be subjected to less heat and is suitable for material that may be damaged due to exposure to high temperature. It is for this reason that it is used in the jewelry industry which has to work with soft metal with low melting points.

•    Resistance Welding – This welding technique requires that an additional sheet of metal is used to cover the pieces that are to be welded together. This gives great strength to a weld, but the process requires expensive equipment as well as the use of additional material to encase the weld which makes it expensive and not suitable applications.

•    Laser Welding – This is the most modern technology available today. High intensity lasers can be tightly focused and produce controllable heat on the surfaces to be welded very quickly. This is perfect for material that can be damaged by prolonged exposure to extreme heat. Laser welding is very accurate and can be used to produce even the smallest of welds. However, because of the high capital cost involved in buying this equipment, the cost of welding is also high.

Although the perception of welding is that of a simple process of heating and joining, it is a high technology industry with huge amounts being spent on research and development to look for stronger, more accurate and cheaper methods. The welding process plays a big role in metallurgy with a constant effort underway to find newer and more weld friendly ways. Look for a certified welding company for all your fabrication needs.
