化工分离器自动焊接工艺设计

Design on the Welding Technology for 0Cr18Ni9 Production Separator

针对大厚型不锈钢化工分离器主体的结构特点和使用性能要求,设计选用了熔化极混合气体保护自动焊打底、反面填充、盖面,埋弧焊正面填充、盖面的新的组合焊接工艺方法,代替传统的手工TIG焊打底、焊条手工焊填充、盖面的工艺方法。通过焊接工艺评定和相关试验研究,并将研究结果应用于产品的焊接,获得了满足产品设计要求的焊接质量,提高了生产率,同时减轻了施焊的劳动强度,取得了良好的经济效益。

According to the structural characters and the using properties of the big thick stainless steel chemical separator, a new welding process of the MAG welding is employed in this paper. The product's welding quality meets the design standard. The high productivity and profit are obtained with the new welding methods. The labor intensity of welding is reduced also.
