Nadcap Approved Welding
Nadcap-accredited aerospace welding that passes inspection the first time. Dan's Certified Welding, Inc. (DCWI) is a Nadcap approved welding supplier for flight-critical commercial and military aircraft components: GTAW/TIG, micro-TIG, orbital tube welding, and in-house stress relief, in Downey, California.
What "Nadcap approved welding" means for your parts
Nadcap is the aerospace and defense industry's accreditation program for special processes, administered by the Performance Review Institute (PRI) and governed by the primes themselves. Welding is a special process: the result cannot be fully verified by inspecting the finished part, so the industry audits the process instead.
A Nadcap approved welding supplier has passed an independent, checklist-driven audit of its welding procedures, welder qualifications, equipment calibration, material controls, and quality system, and appears on the Nadcap Qualified Manufacturers List that primes and their suppliers are required to buy from. For a procurement team, that accreditation is the difference between a vendor you must qualify yourself and a vendor the industry already qualified for you.

Nadcap approved welding processes and materials
GTAW / TIG Welding
Precision gas tungsten arc welding on flight-critical components, Class A, to print and spec, with controlled fit-up, distortion, and heat input.
Micro-TIG Welding
Fine-feature and thin-wall welding where heat control and repeatability decide whether the part passes.
Orbital Tube Welding
Automated, repeatable tube and tube-to-fitting welds for fluid, fuel, and hydraulic systems.
Pre- and Post-Weld Stress Relief
In-house furnace preheat and post-weld heat treatment so one source controls the full thermal history of the part.
Weld Repair
Complex repair welding on high-value components to customer-approved procedures.
Materials
Aluminum, stainless steel, Inconel and nickel alloys, titanium, and carbon and alloy steels.
Why procurement teams choose a Nadcap approved welder
Less supplier risk
The industry already audited the process. You inherit that qualification instead of building it yourself.
First-time acceptance
Controlled procedures and qualified welders mean parts pass inspection the first time, not after a rework loop.
Complete documentation
Every part ships with its traveler, weld record, inspection results, and certification, ready for your quality file and your customer's audit.
