Description

Device for rolling exhaust channel during laser stitch welding of galvanized sheet
Technical Field
The invention relates to the field of galvanized sheet welding, in particular to a device for rolling an exhaust channel during laser stitch welding of a galvanized sheet.
Background
Body-in-white welding is an important link in automotive manufacturing. As one of four workshops (stamping, welding, painting, final assembly), the aim is to splice together a stamped piece of sheet material. The galvanized layer of the galvanized steel not only has a physical shielding effect, but also has an electrochemical protection effect on a steel matrix, 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 a vehicle body and the like and the service life of an automobile, so that the galvanized steel is widely applied to the automobile manufacturing.
However, the presence of a zinc coating in galvanized steel greatly reduces the welding manufacturability of galvanized steel. The reason is that the physical properties of the galvanized steel are greatly different from those of the base steel in the welding process (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 ℃), and the galvanized zinc is severely gasified before the base steel, so that the phenomenon has great influence on the welding process and quality of the galvanized steel.
The existing process methods comprise a plate gap method, an air vent opening method, an element adding method and the like, which can solve the problem that zinc vapor affects the welding quality to a certain extent, but have the problems that the gap is not easy to control, the air vent efficiency is too low, the cost is too high and the like. Accordingly, there is a need in the art for further improvements and perfection.
