LASER-HYBRID WELDING WITH BEAM OSCILLATION

摘要

A method of welding metal components (24, 26) together including moving a laser beam (20) in a first direction (A) along an interface (22) between a pair of metal components such that in the vicinity of the focused beam, metal from each component is vaporized to produce a keyhole (28) in a pool of molten metal (30). The laser beam (20) is oscillated in a direction (B) different from (e.g., transverse to) the first direction (A) such that the keyhole (28) oscillates through the pool of molten metal (30) and molten metal (30) fills into the keyhole (28) as the position of the keyhole (28) changes.
