    Copper Welding vs. Soldering

Do you have any processes that you would like to share with a  fellow sheet metal worker, presently I solder all my copperwork pieces but I am very interested in the welding process if possible.

Thank you, Ed

The Tinman Respondeth:

Ed,
Use deoxidized copper rod or wire and a high temp flux, for torch welding. Try "heat fence", a product designed to hold the heat in a given  area, or wet rags, because of the thermal conductivity of the  copper. I use a silver hard solder, too, a BAg 24.

TIG is good, too, but set the heat way up, with de-ox. copper filler, and use a thoriated tungsten.
