Andrew Cardin did the welding in this video while Jody handled the filming.
165 amps, arc force set to 10 using a Lincoln PowerMIG 210mp. We decided to use some leftover rods so that we show lots of restarts because being able to make a good restart is a fundamental skill... especially in overhead welding.
my number one rule for overhead stick welding is...
"Set the amperage high enough where the rod won't stick even when you hold a tight arc, THEN HOLD A TIGHT ARC."
Aerospace tig welding tests almost always involve a fixture like the one shown in this video. Little details like how you place the chill bars can make a big difference.
Even though it would be rare to weld plain 304 stainless for aerospace, the tips still apply.
Typical test material for th...
In this vdieo, I use a few different tig welding techniques to demonstrate that a pretty weld is not always a good weld. Filler rod size and technique are key factors.
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 dow...
