  • Hammer Welding

    I am currently using a gas shielded MIG for sheetmetal work and am not entirely happy with it. I am about to embark on a project that I believe is applicable to hammer welding. I have tried my hand briefly at hammer welding with the MIG, but I am not satisfied w/ the results.

    What are you experienced guys using for hammer welding sheet metal - are you gas welding, Tig or Mig?? I would really like some advise and correct procedures for going about it before I screw up a big panel... I have searched the web with little success. Thanks.

        It's not really "hammer" welding, it's weld planishing as you weld. originally for gas welding. After tack welding as you weld the seam about an inch at a time you hammer and dollie the weld while hot to stretch it back out and keep distortion to a minimum,and keep things in alignment, works really well.

          Todd pretty much has it, hammer welding uses a forge, anvil, a little borax, and a large hammer. What you are talking about is hot planishing. It relies on having the weld itself soft as well as the base metal, with minimal bead buildup. Mig welds rarely ever adapt themselves to the process as they are hard and BIG. You will find OA welding with RG-45 filler to lend itself the best to the process. Go to www.tinmantech.com and search for videos on the subject of repairing steel body work.

            Alpha......i've done quite a bit of hammer welding both with oxy/acetylene and mig......one option I have found with mig is hammering after you have welded and cooled......Takes a fair amount of hammer dolly work and you do have to use a little more oomph if you will but you can get satisfactory results hammeing cold. That is as long as you don't have a ton of warpage to deal with. I use use hundreds of tack welds to slowly weld the whole seam to keep warpge to a minmum. Makes it alot easier afterwards and you would be surprised how smooth you can planish the metal before even grinding the welds.
