Abstract

The disclosure relates to methods and systems for joining at least two workpieces, including forming a weld joint by moving a machining beam, e.g., a laser beam, and the at least two workpieces relative to one another along a feed direction, wherein the movement of the machining beam and the two workpieces relative to one another is superimposed with a periodic movement in a movement path, e.g., a two-dimensional movement path, which extends in a transverse direction perpendicularly to the feed direction and, e.g., additionally in the feed direction. The movement path has, between two reversal points in the transverse direction, at least one stop point at which a speed component of the periodic movement in the transverse direction is zero. The invention also relates to computer program products and systems for carrying out the methods.
