Brief Discussion on Welding Process and Numerical Simulation of X70 Steel Tube

In this paper, X70 steel pipe with a diameter of 600mm and a thickness of 15mm was selected. In combination with the actual production situation, the welding process under the condition of electrode arc welding is established for the horizontal fixed (5G) position. After the welding is completed, th...

Summary:In this paper, X70 steel pipe with a diameter of 600mm and a thickness of 15mm was selected. In combination with the actual production situation, the welding process under the condition of electrode arc welding is established for the horizontal fixed (5G) position. After the welding is completed, the rationality of the process formulation is verified by the corresponding non-destructive testing methods and related mechanical properties tests. The temperature field of the joint was simulated by numerical simulation software, and the temperature field variation of the joint under different conditions was analyzed.
