通过计算碳当量分析了20MnMoNb与Q245R钢的焊接性,结合实际的焊缝工作条件,选用E4315型碳钢焊条,通过工艺试验确定了焊接工艺及焊后热处理规范,最终获得了良好的焊接效果,并顺利完成了转运容器吊耳的焊接。
The weldability of 20MnMoNb and Q245R steel was analyzed by calculating the carbon equivalent, and the E4315 carbon steel electrode was selected according to the actual working conditions of the weld. The welding process and the post-weld heat treatment specification were determined by the process test, and finally a good welding effect was obtained. And successfully completed the transport container lugs welding.
