Abstract
- It is of great significance to analyze the influence mechanism of MIG welding parameters during thermo-mechanical coupling to improve the MIG welding process. In this paper, the Python script and the birth and death element method are used to realize the transient growth of a weld, the moving load of the welding heat source was realized by a Fortran subroutine, and a thermo-mechanical coupling model for the SUS301L-HT stainless steel MIG welding process is established. The temperature field and the thermal stress field are calculated. On this basis, a response surface model is established by the BOX-Behnen Design (BBD) method, and the sensitivity of welding process parameters to the influence of welding process is calculated by combining the Monte Carlo method with the response surface model. The calculation shows that the welding current and the welding speed have the most significant effect during the MIG welding of SUS301L-HT stainless steel, while the arc voltage has a relatively weak effect on the welding. The V-shaped angle has a great influence on the deformation angle of the welded workpiece. [ABSTRACT FROM AUTHOR]
