Abstract
A method of energy beam welding, as electron beam welding is disclosed, wherein the supply rate of filler material is continuously varied in accordance with the width of a gap between two workpiece parts to be welded together. Further, the specific energy input per area as well as the energy distribution along the weld seam produced are also controlled as a function of the width of the gap. The control may consist in a variation of the repetition rate of beam deflections across the gap or the variation of the amplitude of a beam deflection component parallel and/or transverse of the gap.
