Abstract
The present invention provides a method for laser brazing an Al alloy to a steel sheet so as to produce a lap joint member that excels in bonding strength with respect to the Al alloy. The laser brazing method includes a brazing step of forming a brazed part (9) for bonding an Al alloy (3) to a hot dip Zn-based alloy coated steel sheet (1) in which a coating layer (2) contains 1.0 to 22.0% by mass of Al and a coating weight per surface is 15 to 250 g/m2.
