摘要
本文应用Ｘ射线应力仪对ＣＦ－６２钢制乙烯球罐焊接残余应力进行了现场测量，解决了大型球罐的残余应力现场测试过程中的技术问题。
The welding residual stresses in a 1500m 3 spherical vessel made of CF 62 steel for storing polythene were measured by X ray method in the working field.It was found that the measured residual stresses in the as welded state were quite high and they were sufficiently reduced after postweld heat treatment.
