摘　　要：焊接是钢制压力容器制造和安装中重要的工序,焊接质量直接关系到钢制压力容器在使用过程中的安全性和稳定性,并且对压力容器的工作性能和使用寿命具有决定性的影响。所以在焊接之前,应该对焊件的材质、化学成分、结构类型以及焊接性能等进行全面的分析,然后制定出科学合理的焊接工艺,并且做好焊后热处理工作,确保钢制压力容器的焊接质量。文章主要对钢制压力容器(不锈钢复合钢板)的焊接工艺以及焊后热处理方法进行分析,为进一步提升钢制压力容器的焊接质量提供参考。Welding is an important process in the manufacture and installation of steel pressure vessels.Welding quality is directly related to the safety and stability of steel pressure vessels in use,and has a decisive impact on the working performance and service life of pressure vessels.Therefore,before welding,the material,chemical composition,structure type and welding performance of the weldment should be comprehensively analyzed,and then a scientific and reasonable welding process should be worked out,and the post-welding heat treatment should be done well.Ensure the welding quality of steel pressure vessels.This paper mainly analyzes the welding technology and post-welding heat treatment method of steel pressure vessel(stainless steel composite steel plate),in order to provide reference for further improving the welding quality of steel pressure vessel.
