Background
Body-in-white welding is an important link in automobile manufacturing. As one of the four main compartments (stamping, welding, painting, final assembly), it aims to splice together a stamped piece of sheet material. The zinc coating of the galvanized steel not only has a physical shielding effect, but also has an electrochemical protection effect on a steel substrate, and the application of various common galvanized steels, high-strength galvanized steels and ultrahigh-strength galvanized steels greatly improves the corrosion resistance of parts such as automobile bodies and the service life of automobiles, so that the galvanized steel is widely applied to automobile manufacturing.
However, the galvanized steel has a greatly reduced welding manufacturability due to the presence of the zinc coating layer in the galvanized steel. The reason is that the galvanized steel has great difference in physical properties between the galvanized steel and the base steel during welding (the melting point of the galvanized zinc is 420 ℃, the boiling point is 908 ℃, the melting point of the base steel is 1300 ℃, and the boiling point is 2861 ℃), the galvanized zinc is gasified violently before the base steel, and the phenomenon has great influence on the welding process and quality of the galvanized steel.
