Abstract Twin Spot Laser Welding A novel multiple spot laser welding apparatus includes a bendable mirror means capable of deform- ation receives a laser beam at a single reflective surface thereof. Deformation means forms 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 therebe- tween. Still another laser welding method provides multiple laser spots along a weld seam producing distinct weld pools.
