reb78 Posted May 11, 2015 Share Posted May 11, 2015 Just under the 110 and noticed there was a bit of soot where the pipe joins the back of the centre silencer on my stainless exhaust system. Cleaned up it looks like this Closer There wasn't a lot of soot and it doesn't feel like it's blowing, but I think it is cracked along the edge of the weld. Will this just need a run of weld to seal it up? I presume I can't do it with my mig? Quote Link to comment Share on other sites More sharing options...
ejparrott Posted May 11, 2015 Share Posted May 11, 2015 Looks very much like a crack, either of the weld of the parent metal - I can't really tell from the photo Quote Link to comment Share on other sites More sharing options...
tacr2man Posted May 11, 2015 Share Posted May 11, 2015 The weld doesnt look that it has penetrated very well , so could well be a blow , try some soapy water on it and look for bubbles to be sure HTSH Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted May 11, 2015 Share Posted May 11, 2015 Looks like a crack to me, should be able to plop some weld over that with the MIG no problem. Quote Link to comment Share on other sites More sharing options...
elbekko Posted May 11, 2015 Share Posted May 11, 2015 Yup, that's a crack. Welding stainless with the MIG isn't that hard, just note that the (area around the) weld could start rusting if you use regular mild steel wire. Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted May 11, 2015 Share Posted May 11, 2015 As said. I have extensively modified my Stainless system (from a Disco to a 110) just by using a few bought angles and straights and simply welding them on with a mild steel MIG. Welds perfectly well and after 3 years still looks like new on the joins I did. Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 11, 2015 Author Share Posted May 11, 2015 That's great. Thanks. I had it in my head I needed special wire or something. I can fix that myself then. Did the soapy water. It's definitely blowing, but only a tiny bit. Quote Link to comment Share on other sites More sharing options...
qwakers Posted May 11, 2015 Share Posted May 11, 2015 ideally you should use stainless wire, but a mini spool of that isnt expensive. Quote Link to comment Share on other sites More sharing options...

Soren Frimodt Posted May 11, 2015 Share Posted May 11, 2015 Sadly a common problem with SS exhausts, with mild steel you get rust, with Stainless you get cracks, its just a matter of preference really! Seriously though it does seem like the grade of Stainless used makes a huge difference. Quote Link to comment Share on other sites More sharing options...

Anderzander Posted May 12, 2015 Share Posted May 12, 2015 Just s thought - is it still within a warranty period, with some having lifetime guarantees ? Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted May 12, 2015 Share Posted May 12, 2015 Just s thought - is it still within a warranty period, with some having lifetime guarantees ? And if it is under warranty you might break the waranty if you zip it with the mig, might be worth a phone call. Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 12, 2015 Author Share Posted May 12, 2015 It has a lifetime warranty so they will probably fix it FOC. Trouble is they are in Ashford, Kent (same place HfH had his done) near my parents and i am north of London. I think i will give them a shout as suggested and see if they mind me migging it, otherwise i will have to arrange a Saturday when i am visiting mum and dad for them to zap it up themselves. 1 Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted May 12, 2015 Share Posted May 12, 2015 Takes a loooong time for a blob of mild steel MIG to rust through, on regular exhausts it's never the welds that rust out. Quote Link to comment Share on other sites More sharing options...
