Uniform bending fatigue tests were carried out on butt-welded pipes of an STS-38 (low carbon) steel and of a SUS-304 TP stainless steel. Experimental factors investigated were the amount of uniform mismatch, the effect of the existence of a weld reinforcement, the effect of grinding off the reinforcement toe roundly and the influence of solution heat treatment of the stainless specimen. The specimen was subjected to pulsating bending load with the cycling rate of 250 to 400 cycles/min. Leading conclusions obtained are : (1) Bending fatigue strength decreases with the increasing amount of uniform mismatch. (2) The notch formed by the finishing end of machining inner surface provides more or comparably detrimental effect on fatigue strength, compared with uniform mismatch and with a weld toe. (3) Solution heat treatment on the stainless steel specimen results in remarkable decrease in the fatigue strength.
