I have a project that I am working on that requires joining .040 in thick German Silver (nickel silver) sheet. The joint must be metal finished and polished so color match is important. The preferred method of welding to use a piece of the parent material for a welding rod. I have had limited success (mostly bad) welding this material with an O/A torch using parent for filler rod and fux the joint.. German Silver is a copper based alloy and I have been wondering if TIG welding the material might be an option but I don't have a TIG welder to test it.
Can anyone offer insight and/or past experience joining German Silver sheet. Also can anyone offer advice on appropriate TIG welders for doing this kind of work?.
