How can I improve this weld? I know it has a fish eye 😂 I'm trying to get rid of that! 123 amps 100Hz 64%EN 3/32 filler 3/32 tungsten #6cup 15cfh 1/8 aluminum

Is anyone using an aluminum bench top welding plate to put on top of their welding table? If so, what size, thickness, and what grade aluminum are y'all using? Or what is ideal?

Here i have a stainless steel exhaust mount bracket that holds a titanium exhaust in place. I need to tac weld it. The problem is that if I tac the top part of the 1x1 inch metal flat bar to the stainless steel band, and I go to hot 🔥 the heat can transfer through the stainless steel and cause the stainless steel band to bond to the titanium tube which then will cause a hole. Stainless steel and titanium do not mix well when heated up to a point where they can be tac welded together. I give this warning that if you are in any situation where you need to tac or weld near the point of the two metals touching, be sure they dont bond or else they will have a GALVANIC CORROSION event where the titanium will become brittle and crumble. This happened to me a year ago go when I did this bracket and did the 1 inch bead, not thinking about how much heat transfers through the ss clamp. At the end I had to pry the clamp off and chunks of titanium came off with it that were on the inside of the clamp where the bead was laid. So, in this photo, I hit a super fast and cold tac doing everything I can to prevent heat transfer. The more ya know the better 😌
