Description
Summary:The amount of metal materials is gradually increasing with the rapid development of manufacturing industry. Medium-thick plate aluminum alloy is widely used in heavy military vehicles, marine engineering, and other fields for weight reduction or corrosion resistance. However, it is difficult to obtain high-quality deep penetration welds by traditional welding technology to meet the requirements. Based on the welding solution of plate aluminum alloy, this paper summarizes the deep penetration welding process of aluminum alloy plates and analyzes the mechanism and research progress of various process methods. It mainly includes active flux tungsten inert gas welding, pulse melting electrode inert gas welding, swing arc narrow gap GMAW welding, high energy beam welding and laser arc hybrid welding, etc. The welding technology assisted by external magnetic field or ultrasonic field can also realize deep penetration of the weld, and can improve the weld forming, reduce porosity and cracks and other defects. The research on deep penetration welding technology is helpful to promote the high-speed development of plate aluminum alloy welding to automation and intelligence.
