No. Welding is a profession and a method of holding two pieces of metal together.
This method is easiest for me.
All string instruments can be difficult to learn, but the violin may be the easiest to learn.
TIG welding is a method of welding. A tungsten electrode heats up the metal that is to be welded while a gas, such as argon, protects the weld from being contaminated. This method allows for clean, accurate welds. It can also be used on more metals than any other welding process.
There is an welding school called Tulsa Welding School. They offer best welding education for those who want to learn. Feel free to contact them. Won't regret it.

A journeyman is someone who is knowledgeable about the welding process. Therefore to apprentice with someone who doesn't know much about welding seems futile. Learn from the best if you can.
