摘要：
A laser lap welding method by irradiating of a laser beam from one side of a plurality of overlapped workpieces (1, 2), the method includes the steps of: scanning (La) the laser beam in the forward direction along a predetermined section of the workpieces; reversing the scanning direction of the laser beam at a terminating end (t) of the predetermined section; scanning (Lb) the laser beam in the backward direction and terminating of the irradiating of the laser beam onto the predetermined section, wherein the scanning of the laser beam in the backward direction is offset from the scanning of the laser beam in the forward direction such that a part of weld bead (12) formed by the laser scanning in the backward direction overlaps the weld bead (11) formed by the laser scan in the forward direction.
