| Abstract: | The significance of a new forming process of aluminium alloy in reducing vehicle weight was analyzed.As the background of its application in the rims, the fish-bone-shaped crack experiment on the 3mm thick plate and welding experiment on the 4 mm thick plate using the same welding rod were carried out using three hard aluminium materials(2014, 2024, 2219) and the method of MIG welding.The mechanical properties of the three aluminium alloy welded joints before and after heat treatment were compared.The resul... |
