I've got a problem with a part we are trying to make.
It's long thin steel with some nuts welded on it.
I have a tolerance of 0.5mm.
And as soon as I take it out of the gig it's over 1 mm out. And it's execentuated down the piece.
I've tried welding it as cold as pos, doing one small weld at a time with cooling in between.
Any ideas?
