    Yes, but besides the discoloring you'll also get rust after a short time. Welding stainless with anything but TIG or MIG using pure argon gas will deposit contaminants on the metal that will quickly rust just like plain steel (ask me how I know...). Even with TIG you'll get this, but to a lesser degree. Repolishing will remove these contaminents and 'restore' the surface. One reason to avoid this is the rust will bring pitting, and the pits are stress points from which cracks can start. Stainless is rather prone to cracking when heat cycled anyway, so you don't want to do anything to encourage this. And the more heat put into the weld when doing it, the better the chances of cracks later. TIG uses the least heat, so is the preferred method...

      how about this? Braze a nut onto a worm drive hose clamp.
      Tap drill through and re-tap to clean the brass out of the thread. Make three. They'll be hidden by the heat shield and won't show.
      I like it! Great idea! Gonna do it! Thanks

        For what you are trying to do, silver solder would be much easier and just as strong if not stronger.

          Hi Folks. After deliberating carefully on the accumulated wisdom here, l I decided not to attempt welding my exhaust pipe!

          I used a suggestion by an XSive and used metal 'Jubilee' clips. I drilled a hole through them, just enough for an Allen bolt to go through, then placed a slim nut under the hole and tightened up the clip onto the pipe. The chrome trims then sat straight on the clips and I screwed the cut-down bolts through the holes in the trims and that was the job done.

          I've run the engine to see what effect the heat has on the clips re expansion etc and everything is rock solid with no noises or flapping or whatever. Here's a few pix of the finished pipes. By the way, the trims are still available brand-new from a place in Denmark......

                  Thank you, kind Sirs. The reaction to my idea of welding really made me see sense! It's great to have a wall to bounce one's ball off re ideas, eh? I reckon I'd have blasted a hole through one of the pipes if I'd tried it.........
