Abstract

The length of the beam measured in the plane of the welding has been increased w.r.t. that obtained with conventional, appts. A slight dissymmetry has been introduced to the structure of the gun by slight movement of the radiation head about the axis of firing and/or movement in two directions perpendicular to each other and the line of firing. This appts. enables thin or moderately thick articles to be welded at high speed without deterioration in weld quality.
