ABSTRACT:
A weld bead is disposed between two workpieces to be welded together by feeding the weld metal to a pool which is advancing relative to the workpieces while supporting the pool of weldment from below with a member which simultaneously serves to maintain the spacing of the workpieces and is preferably composed of tungsten. The support member can be constituted as an electrode. The pool-support member and the burner form a unit which is displaced along the welding gap between the workpieces.
