   I've seen the videos of production of chain and it's electric resistance   
   butt welded from what I've seen.   
      
   What diameter wire or rod are you talking about if you TIG weld it. I've   
   butt welded quite a few items in the 3mm to 5mm region with TIG, not had   
   to try larger or smaller, and found the surface tension holds the molten   
   metal in place and forms a nice joint sometimes with a small filler   
   addition.
