摘要

A welding electrode of the filling type for machine or hand welding is formed by providing a longitudinally extending stepped ridge along one edge of a strip which is then bent transversely so that the opposite edge lies in the step and is a projecting portion of the step, underlies the gap, the resulting tubular member receiving the filling. The junction is then welded by tungsten inert gas or electron beam welding to close the shell and seal the latter.
