摘要
Abstract
The application background,technical principle and development status of copper/aluminum dissimilar metal welding technology in the home appliance industry are systematically reviewed.Driven by the goals of lightweight,cost reduction and efficiency increase,and"double carbon",the"substitution of aluminum for copper"has become an important trend in the industry,and the realization of a reliable connection between copper and aluminum is the key.The principles,advantages and challenges of the mainstream technologies such as brazing,laser welding,friction stir welding,ultrasonic welding and resistance welding are analyzed.It is pointed out that inhibiting the formation of brittle intermetallic compounds is the core of the technology.The process selection guide based on the core requirements of specific components of household appliances(such as refrigeration pipelines,heat exchangers,and battery lugs)is constructed to provide guidance for engineering applications.The development trend of this technology towards process compounding,process intelligence and active interface design is prospected,and it is considered that it will play an important supporting role in resource safety,cost optimization and green manufacturing of the home appliance industry.关键词
