Method for producing resistance-welded member

A method for producing a resistance-welded member made of three or more steel sheets including at least one plated high-tensile steel sheet having a base metal strength of 980 MPa or more, the method comprising:

• a main energizing by performing energization with a first current value while compressing the steel sheets between a pair of electrodes with a first compressive force to form a nugget;
• a subsequent energizing by performing, after the main energizing, energization such that a current value gradually decreases from the first current value while compressing the steel sheets between the pair of electrodes with a second compressive force greater than the first compressive force;
• and
• holding the pair of electrodes against the steel sheets while maintaining the second compressive force after the subsequent energizing, wherein:
• the steel sheets are joined under conditions satisfying formulae (1) to (3):
• A≥1.9 Formula (1)
• wherein A=P2/t;
• P2 represents the second compressive force [kN];
• and
• t represents a total sheet thickness [mm] of the steel sheets, respectively;
• 0≤Tdl≤200 Formula (2)
• wherein Tdl represents a compression rise delay time [ms] which is a time difference between an end of energization with the first current value and a start of compression with the second compressive force;
• and
• B≤Tds≤C Formula (3)
• wherein B=0.0011Tht2−2.64Tht+1284.8, C=0.0015Tht2−2.52Tht+1268.6;
• Tds represents a down slope time [ms] in the subsequent energizing;
• and
• Tht represents an electrode holding time [ms], which is a time for holding the pair of electrodes against the steel sheets in the holding the electrode, respectively.
