I had never heard of this company and thought it might interest you. They came to our work the other day with welding rods for various uses. I don't really know anything about welding but I have been sweat soldering copper pipe for many years. Some of the rods they have can be used with a good torch and Mapp gas tank or typical welding equipment. Joining dissimilar metals seemed easy looking with the proper rod and a torch. Once heated the material flows like solder and looks very clean and is very strong. Even with a big vise and hammer the welds did not break.
