Being TIG welders can weld any metal which conducts electricity, has anyone had the opportunity to TIG gold?

Haha oh how I would love to weld 24k gold. I am not sure tig is a common way to fuse gold though. Although it would probably work.

Yes.. micro-TIG setups (tiny torches and very low amps) to attach gold contacts or leads to specialist electronic equipment and also things like dental work..

Bye, Arno.

I tigged silver once when I was playing around welding razor blades. Thought I would see how it worked. Just formed a puddle on an old silver dollar. Behaved pretty well. I have done a bit of copper too but never gold.

I've melted platinum with a TIG welder, but not actually welded it. I just took a bunch of platinum chips and melted them together. It takes a lot of heat to melt that stuff. I would think that gold would melt at a much lower temperature.

I knew an old Navy welder who had a job tig welding gold after getting out.

That was over 30 years ago for him.

Gold has a higher melting and boiling points than copper in fact approaching iron so it should tig nicely without gasing out. Question is why would you when you could use it to lay on a beach in the south pacific while being fed grapes and champagne by some very friendly people
