Orbital Tube Welding

When the need arose in the marketplace for welding of highly critical aircraft hydraulic lines made of 21-6-9 stainless steel tubing, we added “orbital tube welding” to our services in 2006. And now we are approved to Boeing BAC 5974!

Orbital tube welding uses the same process as GTAW/TIG, but the work is performed by a machine, rather than by hand. This process works extremely well in applications that require radiograph inspection with very tight tolerances.


Our company’s precision craftsmen and orbital tube welding machine are qualified by being tested to AWS D17.1. We’re qualified to weld the following materials:

  • Stainless Steels
  • We can also qualify for other materials if you need

These welder qualifications allow us to certify the welds to AWS D17.1, P8TF3, and others. Now approved to Boeing BAC 5974.
