ABSTRACT:
The parallel faces of thick-walled structures to be joined by arc welding are provided an electrically conductive metallic support along and up into the bottom of a gap between the parallel walls for the initial pass of the arc. The metallic support is subsequently gouged from the gap and the union of the parallel faces is completed by filling the gouged space with welding material.
