How are commercial chain links welded? My first guess is using resistance

I find it intriguing that this topic came up. I've been trying to
figure out how to make welded links for things like chainmail,
safety-mail (like the microlink gloves that prevent you from cutting
yourself while filleting fish) and even necklaces.

I just found the following site that talks about Resistance welding...

The Wiki says that currents from 100 to 100K amps are used...

Hmmmm.... I wonder how hard it would be to design a Homebuilt power
supply for a Resistance welding rig?
