➡️It is used be because the high level of heat that is produced in atomic hydrogen welding is high enough to be able to melt and weld tungsten, which can be the hardest metal to weld.

Answer:

Dihydrogen dissociates to atomic hydrogen with the help of an electric arc which generates a temperature of 4000K when allowed on the surface .So dihydrogen is used in welding of high melting metals
