Two Aluminum Cans Welded Together

Here's how Sonja welded two aluminum soda cans together (and below this is another technique you may want to try):
I used 1/16" tungsten electrode, on a miller dynasty 200. I was using aluminum mig wire, 5/64" thick as a filler rod. I started out at 20 amps, and the trick to not blowing a hole thru the can is to start the arc on the filler wire.
Once you get a puddle formed you go from there. I bumped my amps up to 25-30 and started running beads around a few at a time, turning the can between welds. This took me over an hour to do, including prep. It took a lot of skill I didn't even know I had.
Welding two cans together is not something everyone can do. An instructor at my school that has been doing aluminum welding for at least 15 years told me today that I am the first woman he has personally known to be able to do this and that I'm the first student to try it since he has been teaching.
I am so proud right now! This is something the experts have trouble doing! I am taking a welding technology course at a great tech college and I'm looking to get at least 3 different certs and a aas degree. Ive only been in the program for 14 months.

I have tig welded a lot of aluminum. I was bored one day and started welding two aluminum soda can bottoms together. After many many tries I finally got it. The trick is not to start your arc on the can. The heat needed to burn the rod is to much for the can. It will burn through the can. Touching the can with your rod, drip a wad of aluminum by applying the heat to the rod first. Dip your starter puddle then work off the puddle. Continue around applying arc to the puddle not can. After learning this technique their is no such thing of it's to thin to weld.
