Weldall LS200PI practice welds.

I played with my welder today. I welded steel and aluminum butt welding them with no filler.
I tried a quick tack method to tie them together then just fused them. I'm happy with the results and am now not afraid to tackle an aluminum welding project if I get one.

First two photos are steel front and back, photo 3 and 4 are front and back of a piece of 080 aluminum. The last one is 1/8 AL to .080 with no filler.

Looks good. The steel looks like it may have been done a bit to hot. Is the top picture the side you welded from? If so it looks like the weld sunk in a bit. I have gotten that crease in the middle of the weld when I was welding a bit to hot. Other than that it looks like a good start to me.

I ran both sides, the crease side was first and the metal wasn't perfectly straight. The metal filled in the crack a bit. I also think it was a bit hot. I had it set hot to do quick tacks and forgot to turn it down until I was ready to do the back side.

Gadget I would recomend using filler rod when ever possible. Also seems like you getting the hang of it just need to get a little steadier.

I normally use filler but just wanted to try butt welding with no fill using a tack method I saw in a video. As for shaky hands, at my age I'm afraid they will only get worse.
Thanks all for the input, eventually it will all sink in.

Haha gadget the shaky hands are not realy a big deal I'm more talking about your rythm of adding filler. That's all. You will get the rythm down with time. I have thousands of hrs in welding aluminum and I am still perfecting little things so no worries.

This was a big confidence builder today. The AL welding is starting to feel more natural to me now. I have to start coming up with some personal projects.
