My 78 spitfire with catalytic converter suffers from cracks in the exhaust manifold. I had it professionally welded up a couple of years ago, but it broke into two pieces within about a month. Just recently I had to put it back on for emissions reasons, so I did a quick weld up using my own amateur skills and wire feed welder; it got me through the inspection, but is now leaking again. I took it off and tried welding it more carefully, but had trouble. There was a lot of spatter and the beads resisted "sticking" to the metal. And I couldnt get a continuous weld, the welds insisting on "beading up" kind of like water on a freshly waxed car. I tried several different settings on the welder with no luck.
My questions are: Why did the welds behave like that? And does anyone have any opinions about heat temperature epoxies in this application? My local auto parts store carries one; I thought that if I smeared it all over the manifold, it would not only reinforce my welds, but seal the small leaks between beads. TIA!
