ABSTRACT:
A method and an apparatus for the control of the filler material supply rate in energy beam welding as electron beam welding is disclosed. The width or cross-sectional area of a gap defined by opposed faces of two workpiece parts to be joined is measured by radiation, preferably X-ray radiation, and the rate with which filler material is supplied into a welding zone produced by the energy beam is controlled in proportion to the result of the measurement. The measurement may be made in advance of the welding zone and the control is then delayed by a period of time, which the welding zone takes to arrive at the position of the gap, where the measurement was made.
