Effects of residual stress and mechanical heterogeneity caused due to welding on brittle fracture initiation in welded joints are analytically investigated by using fracture mechanics. The residual stress redistribution due to the existence of a crack is considered. The fracture strength can be approximately evaluated by the calculation neglecting the redistribution of residual stress with exception of the much lower stress level. Effects of mechanical heterogeneity on brittle fracture are equivalent in calculations to those of residual stress. The transition temperature (T_i)1/2 is changed by the factors such as residual stress, mechanical heterogeneity and fracture toughness. The elevation of temperature Δ(T_i)1/2 due to residual stress is predominent at lower residual stress level.
