2g TIG Aerospace Weld Test Practice

If you ever need to take a 2g weld test for aerospace or motorsports industries, this video is right down the pike.

I used a #7 pro clear cup for the arc shots to light things up so that you can see the puddle details better. (clear cups help me film and see better).

And I used a Furick Ceramic Jazzy 10 cup for the finished weld.

The specification for aerospace weld tests is AWS D17.1 and while it is designed for aerospace and aviation welding, D17.1  is also used to test welders in the motorsports world.

In fact, there are also other industries who use the D17.1 spec for certifying welders due to the wide variety of metals covered.

The D17.1 specification provides for tests on tubing as well as sheet but a simple butt joint in a fixture like the weld shown is often the first test to get a job.

If you ever need to take a test like this, do yourself a favor and get some plain carbon steel practice pieces in the .040" thickness range like I did in this video...and weld enough of them to where you can easily produce uniform and consistent welds.

Then and only then, you might want to get some more expensive metal like  4130 chromoly, stainless steel, inconel, or titanium.
