Abstract

Some mechanical properties of the submerged arc-welded(SAW) zone between different kinds of metal (SS400+SB450) are investigated and compared with that between same kinds of metal (SS400+SS400 and SB450+SB450). The analysis of the chemical components and observation of the micro-structure by SEM of the weld zone are also carried out. And the effect of the stress relief annealing is examined by comparing tensile strength, elongation, toughness add hardness of SAW specimens before and after the heat treatment.
