I used Alumiweld to fabricate a frame to hold a basket for my mobility scooter. It took me a few times to get the hang of it. The process is similar to soldering. However, you need to get the metal much hotter for Alumiweld to work. Sometimes I melted the aluminum I was trying to weld. Also, you must prepare the site to be welded with a wire brush. This is VERY important. Once you get a good weld, it is extremely strong. I've carried over 50 pounds in my basket using my 1" aluminum tubing frame, and it's held extremely well.
