In order to control the production cost of MAG welding and provide accurate technical support for MAG welding process, finite element software is used to simulate the welding process. Based on ABAQUS finite element analysis software, the temperature field of 8 mm-thick Q235 MAG is numerically simulated, the loading process of welding heat source is simulated, and the temperature field of each stage and the welding thermal cycle law of vertical and parallel points near the weld are analyzed. The results show that the temperature field is steady, the welding thermal cycle is stable, the peak temperature time away from the weld is slightly delayed, and the temperature gradient decreases. The numerical simulation results are in good agreement with the actual changes of the welding temperature field.

Key words: welding temperature field, thermal cycle, ABAQUS simulation, MAG welding, Q235 steel, temperature field, welding heat source, thermophysical properties
