The chemical composition, mechanic property, weldability and corrosion resistance of argon arc welding wire for lowcarbonsteelpipe line are contrasted and analyzed.
In this paper, the residual welding stresses in a lowcarbonsteel 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。
