ABSTRACT:
In automatic energy beam welding, as electron beam welding, of workpiece edges which form a gap of varying width along the weld line, the amount of filler material needed for making up for the volume of the gap is determined by probing the size of the solidified weld bead at a surface of the workpiece and the rate of supply of filler material to the welding zone is controlled on the basis of the result of such determination such that the size is maintained between predetermined limits.
