gwiseman Posted January 4 Posted January 4 Removed this muffler with a block and hammer. Shoulda. cut the pipe and had a new one made (I know) but this happened Already used hammers & punches to get the muffler back where it is as I had pulled the inlet tube out after deforming the metal around it substantially. Cleaned it up more and will take a stab at tack welding this week. 2 Quote
B10Dave Posted January 4 Posted January 4 If you have a set of torches just wire brush the area and use bronze to repair. Won't burn any holes in the thin materiel that way. 2 Quote

SmilinSam Posted January 5 Posted January 5 Fixed a few like that over the years. Only way I can weld it is with the wire feed. Set the welder settings trying out on a similar piece of scrap tubing. Then weld starting the weld on the thicker tube and sweeping over quickly to the edge of the thinner flat of the muffler to melt it together. Any more than a brief sweep/ or moving too far into the thinner material and it melts big holes in the thinner material. 2 Quote
GregB Posted January 5 Posted January 5 And a good flux if you are going the braze repair method that B10Dave mentioned. Try to adjust fit (Small hammer and chisel) so you get minimum gap, if possible. That would probably be my first choice also, as the braze temp will be lower than rusty steel melt temp. 2 Quote
malsup Posted January 5 Posted January 5 Guys, there are some really nice looking stainless steel mufflers, bends and pipe over on Amazon. Do it once - do it right! 1 Quote
