ABSTRACT:
A novel multiple spot laser welding apparatus includes a bendable mirror capable of deformation, which receives a laser beam at a single reflective surface thereof. A deformation device deforms the single reflective surface of the bendable mirror to provide a plurality of laser sub-beams to a workpiece, generating laser spots on surfaces thereof. The apparatus can be used in a laser welding method that provides a common weld pool formed by laser spots transverse to the weld seam. Another laser welding method provides multiple laser spots oriented along a weld seam producing a common weld pool therebetween. Still another laser welding method provides multiple laser spots along a weld seam producing distinct weld pools.
