Abstract (en)
[origin: EP1219381A1] The laser welding method involves welding a workpiece (1) along a weld line by guiding a laser beam (13) along the weld line by moving an optical deflection unit (17). The weld line has rotation symmetry or circular symmetry and a maximum diameter of 20 mm. and the optical deflection unit is rotated.
