Title:
銅端子とアルミ導線との継手及びその超音波溶接方法
Document Type and Number:
Japanese Patent JP7274763
Kind Code:
B2
Abstract:
Disclosed are a joint of a copper terminal (1) and an aluminium conductor (2) and an ultrasonic welding method thereof. One spacing metal layer (3) is added between the copper terminal and the aluminium conductor, and firstly, the spacing metal layer is fixed at a welding end of a base material by means of a manner such as electroplating, pressure welding, electric arc spray welding or electromagnetic welding, and the three parts are then welded together by means of an ultrasonic welding manner. The welding method is suitable for the welding of various joints, the electrochemical corrosion resulting from the potential difference between the copper and aluminium electrodes can be effectively reduced, and the mechanical properties of the joint can be improved.
