Vedclass · Answer

(B) Atomic hydrogen welding is a process that uses an electric arc between two tungsten electrodes in an atmosphere of hydrogen gas. The hydrogen molecules dissociate into atoms in the arc,absorbing a large amount of heat. When these atoms recombine on the surface of the metal,they release this energy,producing temperatures up to $4000 \ K$,which is sufficient to weld metals with high melting points.

The element used for welding metals with high melting points is:
