FATIGUE STRENGTH OF WELDED JOINT FOR TMCP TYPE 50KGF/MM2-CLASS TENSILE STEEL PLATES (SIXTH REPORT)

The authors developed a criteria for evaluating the fatigue strength of the boxing fillet joint at the toes of its run-off bead under compressive stress. Fatigue data obtained by fatigue-testing boxing- welded elementary component test specimens of TMCP-HT50 9KA36) steel plate at room temperature, in the atmosphere and under an axially applied constant compressive load 9R+ - infinity) were sorted out and statistically analyzed. It was decided that the fatigue strength of the boxing fillet joint at the toes of its run-off bead under compressive stress may be expressed as follows for evaluation, the resultant fatigue strength value offering a considerable margin of safety: =1300 Ncf- where 5 : Stress range at 5mm from toe of boxing fillet run- off bead Ncf :Life equal to number of stress cycles to fracture (Nf) under tensile loading.
