Abstract
In a plasma welding process, a voltage is applied between an electrode and an object to be welded so as to generate a plasma arc with a plasma gas directed through a torch to surround the electrode, and welding is performed using the plasma arc as a heat source. The process cyclically varies energy contained in the plasma arc by cyclically varying a plasma gas flow rate.
