Arc welding on a unibody

I'm in the process of finally setting up a welder to install my Clayton's kit. He seems very knowledgeable and confident, and swears that ARC welding is the way to go. This seems to contradict what everyone on the forums is doing, as well as the pdf instructions for the kit. Thoughts? Comments? My brother welds a lot, and says that he doesn't see a problem with it, but I'd like some info from somebody who knows the Jeep unibody specifically.

Seems that ARC welding would be a pain in the *** to do on a unibody.... They aren't all that thick but it could be done with no problem. Use the correct electrode for the steel you're working on. I usually only stick weld THICK steel, using multiple passes. I have done thick sheet metal with it though when I was in my welding class.

I would use an industrial wirefeed for that, seems the easiest to control in that position. With the unibody you are supposed to stich weld, that way there is not too much heat buildup that would warp the metal.

Yeah, he owns a mig, so, I would think that he would use that if he thought it was best. Seems like I'm getting mixed opinions. One argument, "What do you think was used before mig welders came about?"

Stick welding sheet metal upside down is about the most difficult thing you can do in a garage. No way would I do it with a mig available.

Sounds like someone who doesn't know how to use a mig very well to me.

The stick will do it, the MIG will be easier.

Before mig welders there were no unibodies.

If he is a competent ARC welder he can weld on the unibody. I would just make dang sure he is competent before he welded on mine.

I thought they only used arc welding for 3/4" (or more) steel plate at ship yards? The Uni Body is only about 1/16" thick and he will burn right through it.



Seriously: IF you are going to weld them on use the MIG.

i've seen mig welders that will do one pass on 2" plate and i've arc welded body panels before. no one method is exclusive to any purpose.

personally i'd rather tig the mounts into place.
