摘要
在用加氢反应器现场焊接修理过程中,采用环焊缝局部电加热处理来消除焊接残余应力,对其工艺方法和过程进行了介绍,并指出了需要注意的事项,可为在用加氢反应器现场焊接修理后的局部热处理提供借鉴。
The circumferential joints local electric heat treatment method of eliminating welding residual stresses of in-service hydrogenation reactor after on-site welding repair was described.Some suggestions were raised,and some experiences were summarized.
