本文报道了用X射线法测量二台球罐焊接残余应力的方法和结果。结果表明用X射线法进行现场测量是可行的;测量数据表明二台球罐经整体热处理后,焊接残余应力显著降低。
This paper reports the method and result of X-ray measurement of welding residual stresses in two billiards cans. The results show that the on-site measurement by X-ray method is feasible. The measurement data show that the welding residual stress is significantly reduced after the whole two-tank thermal treatment.
