英语释义

1. arc welding that utilizes an alternating-current arc between two metal electrodes to dissociate hydrogen from a surrounding stream so that when the hydrogen atoms recombine into molecules at the surface of the part being welded they supply to the surface for fusion the heat that was absorbed in the arc during dissociation
