Push or pull a MIG weld, what do you do, and why?
 

Just curious about the MIG techniques of the weldor's out there, and their reasons behind them. I am not sure if there is a "right" or "wrong" way, but I know that people indeed do it differently.

I either push or pull, depends on the joint. Typically you'll have deeper penetration with a pulled weld, while a push weld is better for thin metal.

I alwys push. I find there is better penetration pushing.

That's exactly opposite of what I have experienced.
When you pull angling backwards a bit), your arc is hitting the metal at a point that is already built up with filler. When you push, it's angling forward, where the heat doesn't have to penetrate so much newly deposited filler in order to penetrate into the base metal.

In other words, when welding, your puddle has a slope to it. The back end of the puddle is higher than the front. When putting the heat into the back of the puddle, it means that you have to burn through more filler to get into the base metal.

I sometimes pull, but most times I push.
