Low carbon steel joints with tig really require the deoxidisers that fillers provide which is why fusion joints can lack strength and longevity. If you want to tig your exhausts and have flat joints try using er70s-6 filler with good fitup and pulse.

Thanks again guys.
As much as I'd like to use stainless tube, I can't find it in the diameter I need. I'm going for the very best fitup I can - I learned early that its worth the prep. Next step, as mentioned before, will probably be to use Mig wire (ER70S2) as filler, with pulse.
Cheers,

Interesting. Mine is S2, but I can get my hands on some S6 no problem if you reckon it would be better.Coldman wrote:Do you have ER70S-2 mig wire?, it's not commonly used. Most common mig wire is ER70S-6 which would give you a better result in this case.
