The thing about cold lap (weld laying on metal with insufficient fusion) is that sometimes you can have what looks like a very good weld but in fact has cold lap and lack of fusion. That's why is always good to weave side to side or go in little circles unless you're doing thin sheet metal.

Good info, Arc. :thumbsup:

My first instructor, back in the 60's taught us to make little circles to get good fusion at the edges. Then when I started working, most guys there had been taught to go side to side. So as Arc said, either way is good.

Still have to have enough amperage, though. Or it's going to sit on top like water on wax paper.

Post 10 of this thread has a good photo of the results of a cold lapped MIG weld. The tooth on the toothbar is missing and as you can see it was never welded properly in the first place. Just a bead layered on top of the parent metal.

Post 1 of this thread shows a back blade that was not welded very well either. The MIG bead just did not penetrate properly.

Here's a pretty good example of a cold lap Mig weld.

Looks like a caterpillar laying there. :laughing:
