Abstract
The present invention provides a method for MIG brazing an Al alloy to a steel sheet so as to manufacture a lap joint member that excels in bonding strength with respect to the Al alloy. With the MIG brazing method, a bonding target sheet, specifically, an Al sheet or an Al alloy sheet is bonded to a hot dip Zn-based alloy coated steel sheet (1) whose coating layer contains Al in an amount of 1.0% by mass to 22.0% by mass. A target location of MIG brazing is a region between (i) an intersection (C) of one end of an end surface (6) of the bonding target sheet and the hot dip Zn-based alloy coated steel sheet and (ii) the other end (U) of the end surface of the bonding target sheet.
