Description

technical field [0001] The invention relates to an electrodeposition welding device and method, belonging to the technical field of welding. Background technique [0002] Cardiac / vascular endoluminal stents, thrombus filters, interventional guide wires, satellite antennas, micro-device wires and other medical devices and aerospace products have widespread and extensive welding needs for small-sized structures. Such structures can be connected by welding methods such as resistance welding, friction welding, thermocompression welding, and ultrasonic welding. However, the inherent problems of this type of welding method, such as joint softening caused by heat input, brittle intermetallic compounds at the interface of heterogeneous joints, and local functional loss of materials caused by thermal cycling, seriously reduce the strength, toughness and reliability of welded structures, making these Welding technology faces insurmountable application barriers in the fields of medica...
