I have a muffler for my /6 conversion that was shipped with the tailpipes not attached. This was done to allow custom fitment. Can this material be welded using oxy acetylene ? The muffler and tailpipes are 321SS. Any tips are appreciated.

Yes, go to your local welding supply store and ask what filler rod they reccomend. Use a stainless wire brush on a drill to remove the discoloration. Stainless pulls heat like crazy.

Tack it up with MIG, then take it to someone with a TIG.

you will require a spool gun($400 option) because your wire feed tube is contaminated. you will also need a different argon gas mix

It sounds like you have made your decision, but for future reference there is a SS arc rod you could use.

You made the right choice. Stainless takes practice.

Ask them to acid treat the weld. Heating the stainless frees up iron, the acid will react and dissolve it leaving you with the more rust resistant qualities of the stainless you desire.
http://www.aws.org/w/a/wj/2002/05/feature/index.html Any shop that deals with architectural stainless products (like railing) can do this. |

Her's a company that sells the acid, and there's a good pic of with/without treatment, looks like a muffler. I don't know them, just googled it.

I called my mechanic today and asked if he knew anyone that can weld SS and he said he did. I described what was needed and he said no problem so it looks like I have this covered. Thanks everyone.
