Stainless steel exhaust... Small holes by brackets

[issy]

how can I get these fixed? I didn't think my stainless steel exhaust would 'corrode' but some air coming out by brackets holding it to van and the gap is too narrow to get anything there so I assime exhaust will have to come off eventually but garage I asked to fix it said wasn't too bad 'yet' although I wanted it done before it got worse... (garages. :| :evil: :roll: )...

Anyhow...... How can you fix stainless steel issues.. I was told not normal welding .. S ething to do with the metal? Is it possible to use those paste things on stainless? Problem is that some arts of exhaust welded onto heat exchangers (long story)...

Would like to gap the problem for now anyhow... So suggestions?

I had a hole on my old LB stainless stock style exhaust got my mate with his TIG Welder to blob it up as it was easily accessable.
Stainless exhaust systems don't last forever they ware-out. :shock:

Oh poo.... Thought ss would last ageeeeees darn it.... Is a tig welder .. Silly question coming.... A welder???

I'm no welder & it was 17 years ago but as far as a know that's what you use to weld stainless steel due to the chromium content of the steel , TIG NOT MIG so there's no confusion.

Mig will weld stainless if you use the correct stainless welding wire.
It will also weld aluminium if you fit ally wire.
It cant do titanium though - or at least I have not found any titanium wire as yet so have to tig that.

Welding s/steel is the same as welding anything else, you have to use the right settings and the same filling material as the material you are welding. Tig is by far the best type of welding for s/s as it gives the best finish, mig is also possible but you need a reel of s/steel wire which will be expensive. You can also arc weld stainless as long as you use stainless rods. Just remember stainless steel is a very good conductor of heat meaning it gets very hot and the heat travels quickly as well which could melt rubbers and plastic parts nearby. Its best to remove the part to be welded, failing that weld in quick blasts and cool inbetween.
