The invention relates to the technical field of vehicles, in particular to a preparation method of a fender support, the fender support and a vehicle, and aims to solve the problem that in the prior art, when a vehicle runs, the fender support is prone to breakage at a welding joint position. In order to achieve the purpose, raw materials for preparing the fender support comprise an aluminum pipe beam, a steel base and a steel pipe fixedly arranged on the steel base, a zinc coating is arranged on the outer surface of the steel pipe, the steel pipe can be sleeved with the aluminum pipe beam, the zinc coating faces the aluminum pipe beam, and the preparation method of the fender support comprises the steps that the steel pipe is sleeved with the aluminum pipe beam, and the steel pipe and the aluminum pipe beam are welded; the welding temperature is controlled within a preset temperature range, so that Fe (ZnAl) 10 is generated between the steel pipe and the aluminum pipe beam; and the welded steel pipe and aluminum pipe beam are cooled. The steel pipe is galvanized, and Fe (ZnAl) 10 can be generated in the welding process of the steel pipe and the aluminum pipe beam, so that the toughness, the tensile strength and the ductility of a welding joint are enhanced, and the possibility of cracking of the steel-aluminum welding joint is further reduced.
本申请涉及车辆技术领域,具体提供一种挡泥板支架的制备方法、挡泥板支架及车辆,旨在解决现有技术中车辆在运行中挡泥板支架在焊接接头位置容易发生断裂的问题。为此目的,本申请制备挡泥板支架的原料包括铝管梁、钢底座和固设于钢底座的钢管,钢管的外表面设置有镀锌层,铝管梁可套设于钢管且镀锌层面向铝管梁,挡泥板支架的制备方法包括:将铝管梁套设于钢管外,并对钢管与铝管梁进行焊接;控制焊接温度在预设温度范围内,使钢管与铝管梁之间生成Fe(ZnAl)10;对焊接后的钢管与铝管梁进行冷却。通过对钢管进行镀锌,能够使钢管与铝管梁焊接过程中产生Fe(ZnAl)10,从而增强焊接接头的韧性、抗拉强度与延伸率,进而降低钢铝焊接接头开裂的可能。
