Abstract (en)
[origin: WO2019197298A1] In a method for laser welding two overlapping workpieces (2a, 2b) by means of a pulsed laser beam (3), more particularly an ultrashort pulse laser beam, which is directed through one workpiece (2a) to the other workpiece (2b) and is moved in a feed direction (10) relative to the two workpieces (2a, 2b) in order to create a weld seam (12) between the two workpieces (2a, 2b) resting against each other, the invention proposes that a deflection (11) back and forth of the laser beam (3) directed transverse or parallel to the feed direction (10) is superimposed on the laser beam (3) moved in the feed direction (10).
