Dimensional restoration is a big part of aerospace maintenance.
A whole lot of aerospace tig welding is restoring worn metal.
And that often involves being able to weld a very small bead on an edge.
The thinner the metal, the more difficult it is so its good to start thick and work your way down to the thickness of the actual job
This is a collaboration video with Jody Collier and Roy "Crummy" Crumrine.
Roy and Jody both do job shop work like this on the side and this aluminum welding job is very typical of the type of work we get. Often times, the machine shop will even make a fixture to help avoid mistakes and make the...
This is part 3 in a "how to tig weld aluminum" series. this video is about AC frequency adjustments and when to use different frequency settings.
Rule of thumb here is higher frequencies seem to help on thinner aluminum and lower frequencies help on thicker aluminum...especially for tig welding...
This video is about tig welding aluminum on AC at 50hz and at 250hz.
there was a noticeable difference at the 2 different settings. 50hz got completed penetration and 250hz did not penetrate.
I tried to keep travel speed the same for both welds by using a motorized welding positioner turntable.
