Who else has seam welded their Chassis?; besides me

 

Not me....at least not yet. I have seen the AE86 guys spot weld their cars in certain key areas.

Banzaitoyota, any pics and writeup regarding seam welding the FC?

 

I might want to come check that out!

 

I could make one...When I get some free time.

1.The key to a good seam weld is removing the "SEAM SEALER" from the joint you are going to be welding. A good scraper and a variety of razor blades helps.
2. Once the major portion of the seam sealer is gone, I will go over the seam with a Propane or mapp Gas Torch to burn off the rest of the seam sealer.
3. Next, remove all paint and/or corrosion on the seam until the metal is shiney.
4. wipe the soon to be welded area with MEK or Acetone to remove any impurites
5. Weld in short (3/4" -> 1") tacks, alternating from each end seam. DO NOT WELD 1 CONTINOUS BEAD!!!!


I use a HH135 MIG with 90/10 Gas and .023 Wire

BUC: You guys have been invited out numerous times!!!

 

If you spot weld your car in just a few spots, you transfer all that stress to the next weakest spot. Either do the whole car or don't do it at all.

It would take A LOT of free time to do a whole car. Power to you.
