Abstract

The invention relates to a device and a method for welding a metal wire and a plate under laser impact loading and belongs to the field of high-speed impact welding. The device comprises a laser generation system, a welding system and a control system, wherein the laser generation system comprises a pulse laser, a reflector, a focusing lens, a focusing lens bracket and a focusing lens position adjusting device; the welding system comprises a restraint layer-adsorbing layer-impact plate-protective coating component, a restraint layer bracket, a restraint layer position adjusting device, a pressing block, the plate, the metal wire, a metal wire clamping device, a workbench, a three-coordinate moving platform and an L-shaped pedestal; and the control system comprises a computer, a pulse laser controller, a three-coordinate moving platform controller, a displacement sensor and a restraint layer position controller. The device and the method for welding the metal wire and the plate under laser impact loading have the advantages that solid welding of the metal wire and the plate can be realized; a heat influence region does not exist after welding; production of intermetallic compounds is avoided; the welding quality is high; and the mechanical property of a welding joint can be improved.

Description

technical field [0001] The invention relates to the field of high-speed impact welding, in particular to a welding device and method for metal wire and plate under laser impact loading. Background technique [0002] In recent years, with the rapid development of electronic products, precision instruments, sensors and other industries, the demand for micro devices is increasing. The related micro-device soldering has more and more extensive demands in the manufacture of micro-device. The main objects of micro-device welding are usually thin metal parts, foils, wires, etc., which require very high welding precision and process parameters, so welding is very difficult. In addition, soldering quality not only directly affects the stability and reliability of micro-devices, but is also a key issue in the micro-fabrication process. [0003] At this stage, the main methods of micro-device welding include fusion welding, brazing, ultrasonic welding, pressure welding, laser welding...
