Seam Welding R32 Gts-t Chassis

[Proximity Motorsport]

Hey guys,

Ive got an r32 gts-t that I should really get my act together and make a build thread for soon. Its been off the road for over 6 months now and its almost a bare shell atm. I have cut all the rear 1/4 panels out and searching for gtr rear fenders to make steel widebody to fit 18x11.5" rear wheels. So i need to weld up where I have cut metal out from rear gaurds, so while I have the mig out im going to weld all the unwanted holes in the engine bay, and then I got thinking, the car is mainly for drift, it has a 6-point bolt in cage which im considering welding in, just gotta call my engineer tomorrow to check if it will be street legal. So im considering seam welding the car.

I have been reading plenty of build threads and reading plenty of sites on google, but most of them are for rally cars, showing cars that are nothing like skylines. So im here, hoping that some people can give some hints on where to weld, and any tips, photos, different techniques.

Im thinking spot welding every 1" will be the best, because i dont like the idea of stitching due to the heat generated and the effects of warping. Obviously up around the top of the strut towers is a good place to start, but from what I have seen noone welds down around the chassis rails which had me buggered?

So if you can give hints on where to weld mainly inside the cabin. On another note I will not be welding both sides of chassis, just the inside (top).

What have you guys done for paint removal for weld prepping? Im thinking just a 4" angle ginder with a wire wheel attached to it?

Any help and pics are greatly appreciated,

thanks

I havent got mine welded yet but i have grinded back all my seams ready to go. Basically weld any part that theres a seam. Im planning on doing 1 inch welds on and off whereever possible.

Grinding back i just used a drill with a wire wheel attached.

Thanks for the pics. Your lucky, got a hoist. I dont feel like rolling around on the floor with a mig welding the underside of the car

As far as I have read, if you seam weld half the car, the other half will be alot weaker, and crack. Is this true? If I only seam weld one side of the seams is it pointless, or maybe even worse for rigidity, and strength?
