Chrome Moly welding?
Hey i'm looking for some info on welding chrome moly tubing. My buddies' son has a go kart and they want to put a bigger engine on it so they need to move one of the cross bars. I have been welding for quite a few years but mainly on things quite a bit larger( D-8, D-9, ect.) I have a Trailblazer 302 w/ 12 RC wire feeder and a Dynasty 200 DX. Need to know the best process and what wire or filler metal to use. Thanks...

I read on the Internet somewhere that you should weld it with oxy-acetylene...

Lots of stuff on this subject.
Do a search. You'll find enough stuff to make your eyes hurt.
Long and short of it is...I'd tig it with ER80S-D2 or ER70-S2.

Well if you had searched this topic you would have found about 84 pages dealing with this subject. The short story is, with what you have, Tig with ER70S-2. Stresses on the joint will determine if you need to perform any post weld operation.

If the OP had said he had that as an option I would have suggested it Originally Posted by MAC702

One thing to keep in mind, on a Kart the suspension is the flex in the frame. In the wet, most of the bracing comes off, on a high grip track bracing goes on.
If you are changing cross bars, that part needs to stay in line, engine and axle sprockets that is.
Keep an eye on the welds when you are running it, the frames move and twist a lot on the track, especially in high g turns.
So what are you changing from, to?

Well, if the frame fails they will blame you, and if the is injury involved, they will come after you. Yes Dad is all for it, but Mom will hang you ass. Having never welded chrome moly, I dint think this is the place to learn. Originally Posted by ROD BURNER
