摘要
This is a sheet steel overlay welding method comprising: a spot welding step in which a joint (110) is formed between a first steel plate member (1x) and a flange part (2) of a second steel plate member (1y) including the flange part (2) and a vertical wall (4), the joint formed by spot welding in a state in which the flange part (2) is superimposed on the first steel plate member (1x); and a laser welding step in which, after the spot welding step, a weld bead (120) is formed by laser welding in a region between a bend end point (3a) of the vertical wall (4) and the gasket (110). the weld bead (120) has a length dimension (1) that is equal to or greater than the diameter (dn) of the joint (110), and a width dimension (w) of 0.5 to 3.0 mm.
