Video shows a 1G AEROSPACE PRACTICE TEST USING COLD ROLLED STEEL 038" at 48 AMPS.
Also compares using pulse settings to straight current.
If you are thinking about an aerospace welding job, edge beads are a great way to practice for a lot of the common tasks in aerospace tig welding.
And as far as practicing for an aerospace welding test goes, that alloys like inconel and cobalt are very expensive.
But if you can run a very consistent bead on plain cold rolled steel then you are well on your way.
