THE EFFECT OF TENSILE STRENGTH ON THE FATIGUE LIFE OF SPOT-WELDED SHEET STEELS
Tensile-shear spot-weld specimens were tested to determine the effect of base-metal tensile properties on fatigue life. Four sheet thicknesses were investigated. Base-metal yield strength ranged between 186 and 757 MPa (27 and 110 ksi). Results showed that fatigue life was independent of base-metal strength for lives greater than 10,000 cycles. At shorter lives, fatigue performance improved with increasing base-metal strength. For a given cyclic load range fatigue life increased at all lives with increasing sheet thickness. Fatigue results from both this and a previous study were used to develop a spot-weld fatigue design curve relating spot-weld tensile-shear fatigue life to the correlation parameter.
