Abstract

The present invention addresses the problem in relation to spot welding of steel plates having a tensile strength of 750 to 2500 MPa in which the toughness is liable to be insufficient and a sufficient CTS is difficult to ensure of ensuring a sufficiently high joint strength in particular CTS in a stable manner; and providing a highly reliable spot welding joint in which CTS has been ensured in a stable manner. In this spot welding joint the P concentration is measured at a pitch of 1 µm in a rectangular planar region that measures 100 µm × 100 µm is perpendicular to the plate surface and is centered on a point located 100 µm inward from the end part of a nugget in a direction parallel to the plate surface to obtain a measured value of the P concentration for each of the 100 × 100 measurement points; and the average values of the measured values of the P concentration of 20 adjacent measurement points from amongst the 100 × 100 measurement points arranged in a row along the direction parallel to the plate surface are repeatedly calculated while shifted by one point at a time thereby obtaining 81 × 100 average values. In this case the number of average values exceeding a value equal to twice the average P concentration is 0 to 100.
