Having been practiced for several years, a new butt method for spiral welded pipe, the two spots tack-weld butt was made out. 通过几年来的实践,摸索总结出了一种螺旋焊管对接新方法&两点点固对接法。
In this paper, the residual welding stresses in a low carbon steel girth butt welded pipe are calculated with a nonlinear finite element code ADINA. 本文利用ADINA非线性分析有限元程序,对低碳钢管道环焊缝接头焊接残余应力进行计算。
