I would like to thank everyone that helped me out. I can now weld two pices of aluminum pipe together now and tack them with minimal filler rod. I still need to work on my welds but I am showing pic now that I can weld aluminum together. I will keep practicing on this piece of pipe till there is no more room left to weld lol. I think my welder is a bit close and blowing out my argon so I need to move the table further away from the welding stand.
