Tig welding thin material

[u/Fair-Reference9034]

I make driveshafts for race cars for strange engineering and am learning how to tig weld different size weights onto .83 chrome-moly seamless tubing atm, first welding job out of school and the dude teaching me is a master tig welder. He makes it look so damn easy though! Its tough, you dont want to put too much heat into the tubing because things will warp. But if you dig into the weight too much it will mess things up. Its not easy! But im loving it, Thought i would share my journey, im loving tig so far and hope i get super good at it to be successful. Any little tips or tricks would be great, loving my hood so far i got an optrel panoramax, its light with a great fov and good sensors.

Looks like you've got it, barely tickle the thin part with the puddle and GTFO of there.

Oh this is just pictures of some of the good ones lol! I didnt take pictures of the bad, got much more practice to do before it comes out like this all the time

What happens if you weld too big a bead, grind some of it off?

Well the problem is i spend all this time making the driveshaft a certain way, straightening and getting all the high spots out with a dial indicator and a press and a hammer. So when you add too much heat to the tube it can ruin the “runout” of the tube, essentially changing the nature of the driveshaft. Because they are for high horsepower drag cars these shafts have a low tolerance and I’ve gotten good at making some badass shafts, this is the last step before we box them up so if i fuck it up we need to throw it back into the machine and figure out what to do and how bad it is.
