摘要
由中国广核集团自主研发的ACPR50S实验堆设备,采用在马氏体不锈钢导流环腔本体的上下端面堆焊镍基690合金,来满足进一步焊接免除热处理的需要。在成功开发自动TIG前送丝堆焊工艺的同时,通过焊接模拟分析手段进行了研究分析,优化了后送丝自动TIG堆焊工艺,解决了后送丝焊工艺的焊接裂纹问题,最终,实现产品导流环腔全部堆焊焊缝无损检验一次合格。
In the ACPR50S developed by China general nuclear power group,the Inconel 690 alloy was needed cladding on both side of martensitic stainless steel guide annular cham-ber for heat treatment exemption.In this paper,the technology of forward wire feeding process of TIG cladding was developed.In addition,the back wire feeding process of TIG cladding was optimized by welding simulation to solve weld crack problem.Ultimately the product is qualified.
