tips on mig welding a flange?
I tried mig welding an exhaust flange a couple days ago, and I failed miserably, big bunches of filler rod and holes all over the place 
Does anybody have any tips or tricks on doing this so I dont mess it up again?

Get some same grade and thickness metal, and practice first.
That way you will get used to it, and you can find the best voltage/wire speed for the metal.

Ive never had any trouble welding flanges. Some people talk about warping but that is just from too much heat. A good way to keep it from happening is to do little sections at a time and kinda overlap where you stop and start. Let it cool some inbetween and you should still get good penetration. Good luck.

Right. There is nothing that says you have to sit there and watch it dissinegrate. Just pull back and let it cool down if it heats up too much.

i've never done it before but shouldnt you mostly lay the bead on the flange instead of the pipe? that way it wont heat up the pipe too much and melt through it. it will put more heat on the flange. but if youre just referring to making a flange and not talking about the pipe at all, then i dont know

The thin stuff is heating up too much and thats whats causing the holes.. Aim more towards the flange like 98AEX said.
cut it off and do it over, you'll feel better
