Like riveting using bolts is an irreplaceable technique of joining two pieces of metal without welding. Stick welding otherwise known as shielded metal arc welding smaw stick welding is a two handed method like tig. Tig welding sheet metal.

But the discs wear down quickly cut slowly and shrink in diameter as you use them. Like with welding bolts are used everywhere from cars to planes to bicycles.
