全自动双钨极氩弧焊在反应堆压力容器冷却剂泵泵壳内壁堆焊中的应用

Application of Fully Automatic Double Tungsten Argon Arc Welding in the Build-up Welding of the Inner Wall of the Coolant Pump Shell of the Reactor Pressure Vessel

泵壳内腔结构复杂、空间狭小,采用全自动双钨极氩弧焊方法进行泵壳复杂内腔曲面的堆焊,实现了泵壳内壁全自动堆焊,提高了泵壳内壁堆焊的质量和效率,大幅降低了操作人员的劳动强度。

The inner cavity structure of pump shell is complex and the space is small.The fully automatic double tungsten argon arc welding method has been used to perform build-up welding on the complex inner cavity surface of the pump shell.The fully automatic build-up welding of the pump shell inner wall has been realized,the quality and efficiency of the build-up welding of the pump shell inner wall have been improved,and the labor intensity of the operator has been greatly reduced.
