摘要：
Welded joints represent locations where failure is most likely to occur in welded structures. Welded joint failure depends on their vulnerability to crack initiation and growth. These factors are significantly influenced by the welding technology. The effect of welding technology on the frequency of welded joint failure is complex, and has been thoroughly researched in literature. However, there are still numerous factors whose influence is not sufficiently explained. In this paper, the ratio of strength and plasticity of parent materials and weld metals on deformation properties of welded joint zones were analysed, along with the effects of groove edge temperature on cooling time in the heat affected zone and the effect of multiple defects on local stress increase.
