Abstract On the basis of the uniaxis tensile tests of several mitre welding joints, a mathematical treatment for calculating loading capacity of the butt welding joints under complex stress condition was worked out and an empirical formula is given as:σ_(eq)=(σ_w~2+σ_wτ_w~2)~(1/2) The theoretical consideration of this formula is easily approached by the plasticity collapse and the fracture mechanics. It is also clarified that the conventional understanding about the loading capacity in mitre welding joint being always senior to that in perpendicular one, and its related calculation, as well, seem to be not entirely correct.
