The muffler shop where I took my car used a MIG(Metal Inert Gas) welder, if I'm not mistaken.

MIG with mild steel wire would be the easiest and cheapest method.

MIG is most common because of the self feeding system, just make sure if it's a stainless system you need to use weld wire that is for stainless steel or the weld will crack.

I used the mig at work, MAKE SURE THAT YOU TURN THE VOLTS DOWN, exhuast pipe is very very easy to burn through. I turned it down to about 2-3 volts and a wire speed of 5. with that setting you can basically "do no wrong."

Haha, yeah, turn that sucker down... I have a funny story that could pertain here...

I was bored in metal shop toward the end of my second year, I had already built a "throne" (a chair that ended up a little -too- wide) and I was just trying to come up with something to throw together. I found some old really small thin pipe and some half inch angle iron. I cut the angle iron and bent it into a triangle, and then I was going to weld the pipes onto it to make a miniature table... Well stupid me forgot to turn the volts down on the stick welder, it was at about 120-130 volts I believe (memory is foggy, 2 years of high school lay inbetween this time and now)... Well I clamped up, suited up and kicked the machine on, and threw my helmet down..... scratched once on the table to get my bearings and then tapped to start my bead... well the second I tapped it was all over... that pipe was a molten puddle of metal before I could say "oh #%@!"... I attempted to draw it out but it was all over... kicked the machine off and went to survey the damage... Of a 10 inch long piece of pipe, half of it was molten and running down the sides of my 'table'... I made sure no one was watching, and quickly discarded of the evidence. Moral of the story: turn the volts down!
