Welding

Thursday. I was at work...a 71 C-20 rolled in. The guy asked if we could fix his exhaust. It had duals on it. Down the right side just before the muffler it had rotted out. I cut out the rotted part and was looking for pipe to put in its place. We didnt have the right size. I told the boss what I needed and he said... use some of the bigger pipe and fill the gap with weld. I am not a pro welder. But from what I have read and heard people say this is something you shouldnt do. I did what I was told but wasnt happy about it....and I felt I had done something terribly wrong. I have a feeling I will see that truck again.

It depends on how much you had to fill. Fitup is important to weld joint quality, however, it sounds like the system on that vehicle is on its last legs anyhow.

i do that all the time. friends come to me for cheap mufflers to be welded on as cheap as possible. they never fit right, but i weld em anyways. never had a problem with leaks as long as you fill the gap. i leave most the gap on bottom usually and a tight fit on top, easier to weld under the car.
