Abstract: PROBLEM TO BE SOLVED: To provide a laser welding method for surface treated steel sheets, a method that enables dry fine solid particles to be used directly as spacers and that thereby eliminates special post treatment such as a drying process to help improving productivity as well as reducing manufacturing cost. SOLUTION: On one 1 of the two plated steel sheets to be welded, there are deposited fine solid particles 3 such as steel beads for shot peening by means of a cladding laser torch having a fine particle passage. Then, on this surface treated steel sheet 1, the other one 2 is superposed through the fine solid particles 3, and subsequently the superposed parts are laser-welded. Between the two plated steel sheets 1, 2, a minute gap is maintained by the fine solid particles 3; therefore, in the laser welding, gasses generated by the evaporation of the metallic components in the plated layers 1a, 2a are discharged outside through the gap, enabling a quality weld metal 5 free from blowholes to be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for lap laser welding, by which method and apparatus, the generation of large weld cracks can be suppressed by suppressing the propagation of minute weld cracks, which are caused in a bead, in welding directions.
SOLUTION: A welding torch irradiates a two-plate overlapped workpiece W with a laser beam B. A welding operation is carried out while swinging the welding torch toward right and left with respect to welding direction F making the irradiation point of the workpiece W as a center. The bead 6 is varied so as to continuously change its tilting angle from a rightward tilting state 6A to a leftward tilting state 6C via a vertical state 6B in a plane perpendicular to the welding direction F, and further so as to change its tilting angle in the reversed order. Therefore, the bead 6 continues in the welding direction F while waving with a required cycle. As a result, even if minute weld cracks have been generated in the bead 6, the propagation of the weld cracks is suppressed halfway, and the minute weld cracks do not grow to large weld cracks.
