Noticed my frame has a crack. Is this weldable? COMPKART covert 3.0

Definitely repairable. Pretty common crack across brands. Doesn’t make it suck less though.

James is right. THE MOST common crack in the history of karting. We repair about one a week in our garage for folks at the track. Pretty sure @Matt_Geist could weld seat struts with his eyes closed now.
Get her welded back up and it will be like nothing ever happened.

I crack most seat struts out of the box moving it to fit the fatty seat.

We’ve gone through a few rolls of welding wire on that joint for sure

You are mig welding them?

Yes, sir. Flux core mig welder from Harbor Freight. Just ugly enough we don’t charge anything but plenty strong enough to last a long time.

Oh yeah like Derek said flux core for the win. If you’re in a hurry you just start hitting it with weld and the flux wire does a very good job of welding through powder coating once the metal heats up.

Damn, we are welding through powder coating too. I always thought the cleaner the metal, the better the weld.

That is correct, to repair it correctly you’d have to grind off the paint before welding it up.

I’ve done plenty of gasless-mig welding but I would not try it myself.
Just take it to an engineering shop who does TIG welding and get a professional to do it. I don’t really think they will charge too much in the scheme of things.
Remove any parts before you go to save them the time. Don’t need a burnt seat or cables.
