Thread: More aluminium welds

Tweet

My instructor says these look pretty good.

Looks better than mine! LOL... it's all practice... once you get your hand(s) trained... it becomes second nature.

I can stick weld like a ... IDK.. but tig? Not so much. I want to get a spool gun for my mig, maybe it could help?? LOL..

Looks like I got a duplicate post... wooops..

Aluminum is interesting stuff.

A weld not pictured, is perfectly smooth and shiny. The instructor said it was too hot, and although it is not of importance to the weld ( visual only) that he likes to see the ripples. And, i guess, most people do too.

Oh and edited for inquiring minds, it was AC, 115A, pure tungsten electrode, mostly pedal to the metal, and a 1/16" rod, didn't notice the alloy.

Oddly enough, I can (with a few minutes practice) get my mig welds to be one continuous bead and my teacher didn't like itfor almost the same reasons. But the biggest was not having the puddle bridge the gap. But even when we flipped the pieces over and the joint was in the middle of the puddles path of travel..

I still got the same critique! So I latched it down in the vice and tried to break it, and it finally broke next to the weld! The weld was a good one, it just didn't "look" like the picture. SO I still do it once in a while... it just happens, I don't think about doing it. If the joint opening is wide then I pull the puddle side to side like always.. but when it's tight I just "go continuous".... LOL..
