摘要

不锈钢复合钢板的基层与复层交界处的焊接属异种钢焊接，其焊接性受复层和基层的物理性能、化学性能、接头形式及填充金属等多种因素的影响，常产生焊接裂缝等问题。通过分析压力容器中筒体纵缝、筒节间和筒节与封头间的环缝焊接质量，探索在具体项目中，不锈钢复合板焊接合格率低的成因，提出了采用组合坡口设计和改变焊接顺序的具体改进措施。通过实施改进措施，将压力容器Q345R/S31603不锈钢复合板的焊接合格率从78%提升到了100%。

Abstract

The welding at the junction of the base layer and cladding layer of the stainless steel clad plate belongs to dissimilar steel welding. Its weldability is affected by various factors such as the physical properties, chemical properties, joint form and filler metal of the cladding layer and base layer, and often causes welding cracks and other problems. Through the analysis of the welding quality of the longitudinal seam of the cylinder body, the cylinder section and the circumferential seam between the cylinder section and the head in the pressure vessel, the reasons for the low qualified rate of welding of stainless steel clad plates in specific projects are explored. The specific improvement measures are proposed, such as the use of combined grooves design and changing the welding sequence. Through the implementation of improvement measures, the welding qualification rate of the pressure vessel Q345R/S31603 stainless steel clad plates in this project has been increased from 78% to 100%.
