| Abstract: | The welding performance of the Sweden Vivitar Weldox700E high strength steel was analyzed. The microstructure and physical properties of the materials were systematically tested, and the microstructure of the heat affected zone and the problem of decline in toughness were analyzed. The results show that Weldox700E steel has good weldability, and there is a linear correlation between the organizational structure and the impact toughness, which provides a theoretical guidance for enterprises to determine the relation among organizational structure and physical properties in the welding process evaluation. |
