They never could keep help in the place because the pay was low but they needed a few decent welds on the hitch and axles. "Welder training" thus became welding a near continuous bead on top of the frames with some kind of mild steel rods they bosses called drag rod. They ran it at fairly high amperage always starting about 5' from the tail end moving forward. The result was it warped the frames up and when finished building on top of them they were close to flat under the weight of the home. Also when a hitch welder found himself a decent paying job he would be replaced by an experienced "frame welder" [Reply]   [No Email]

Reason why, generally the weld ends up in the way, and you have to grind it down later. Now if the weld is needed anyway, that's a different story. I'd much ratter use the heat from a torch.

I never worked at the trailer place but the first thing down on the channels was a fabricated steel crosssill? They ground the beads down a bit where they had to go and welded them down. As a metal fabrication plant it was all pretty crude,, as a matter of fact the entire operation was, LOL [Reply]  [No Email]
