In order when welding workpieces (10) having thick walls with an energy beam (13) to achieve a large machining depth (28) with a narrow fusion cross-section (31), the energy beam (13) in the machining direction (22) is continuously directed with reversal of the direction onto two beam incidence sites (16, 17) of the workpiece (10), the energy beam (13) penetrating deeply into the workpiece (10) at each of the two beam incidence sites (16, 17) with the formation of a capillary (23), and the energy beam (13) acting twice, at successive times, on approximately the same point (20) of the workpiece (10) (Fig. 1). <IMAGE> |
