摘要
本文针对目前小型压力容器行业焊接实际情况,分析了保护气体与焊接工艺稳定性、焊缝成型、焊缝力学性能的关系,为小型压力容器单面焊双面成型工艺改进提供了可靠的技术保证。陶瓷衬垫富氩MAG焊用于小型压力容器的焊接加工,焊接接头综合性能优于二氧化碳气体保护焊,具有推广应用价值。
This paper analysed the relationship between the shielding gas in welding process stability, formation of weld, the weld mechanical properties for welding conditions in the small pressure vessel industry at present to provide a reliable technical guarantee about welding process of one-side welding with back formation for the small pressure vessel. Ceramic liner MAG welding technology applies to small pressure vessel to be better than that of CO2 gas shielded arc welding. It is worthy of popularization and application.
