I am trying to tig two flat pieces of .125" aluminum together with a tight butt seam. When the puddle starts each piece melts and pull away from the other
creating a void. It's like they're repelling each other. The only way to stop it from continuing is to get some filler to bridge the gap and go on. I've seen welds without filler before. Is it normal for the edges to do this? I don't see this as being any different than doing spot welds that do the same for me.
The pieces are flat on a table when welding.
