摘　　要：介绍了先进的鲁奇炉代表型MARK#Ⅳ/4型φ3 800 mm鲁奇式加压气化炉壳体的焊接工艺及相关要求。根据产品的结构特点确定试验方案,在试验的基础上针对产品制造过程中的一些疑难问题进行方案论证和工艺攻关。制订了科学合理的焊接工艺方案,采取一系列措施保证产品质量和控制焊接变形,实现壳体纵环缝焊接采用窄间隙埋弧焊自动跟踪压道焊工艺。成功地解决了鲁奇式φ3 800 mm加压气化炉壳体焊接在质量性能、控制焊接变形等方面存在的难题,获得了满意的焊接效果。该项目的研制成功为承制大型疲劳容器和耐高温、高压的机械传动设备积累了宝贵的经验。The welding procedure specification and the concerned requirement for the shell of 3 800 mm pressurized gasifier with the advanced -MARK* IV/4 type is introduced . The test plan is to be determined based on the construction characters. On the basis of test the plan is proven according to the difficulty points in the producing process and find the suitable technology in the manufacturing. While the scientific reasonable welding procedure plan, assure quality of the product and control the deformation caused by the welding by means of a series of technology , narrow gap automatic tracing bead welding is adopted for the longitudinal and girth welding of the shell. The most difficult points are solved for welding the shell of large pressurized gasifier such as assuring the welding quality and controlling the deformation caused by welding, the welding result is satisfied. The success for this term study, valuable experience is accumulated for manufacturing large fatigue vessel and high temperature high pressure mechanical driving equipment.
