The name of the rod is alumiweld. http://www.alumiweld.com/

I found it of all places at Harbor frieght stores.

I have tried this rod and was quite reluctant to as i have a $3000 tig welder. how could this stuff even work was my thought. I was quite suprised as i think it has potential in certian applications.
.
The main reason i wanted to try this is that i have a muffler that was given to me. It looks to be welded together with this same type of process. This may not be the same welding product the muffler company is using but it is very similar as it looks like it was soldered and not tig welded. by the way this muffler cost over $100 and uses this type of welding process.

Here is a test piece i made out of a 3/4" thick section of square tube. i used sheet aluminum cut to size to weld to the ends. the far side is tig welded and the near side is alumiweld.

Clean metal is important in this process and it does take some practice to get it right. this process has great potential in the muffler application.



another alumiweld joint. I dont think i had enough build up in the joint for it to look good but even like this it is hell for strong.
