Title:
WELDING METHOD USING HIGH-FREQUENCY VIBRATION-CAUSED COLLISION WITHIN MICRO DISTANCE
Document Type and Number:
WIPO Patent Application WO/2024/051203
Kind Code:
A1
Abstract:
A welding method using high-frequency vibration-caused collision within a micro distance. First, a first welding part (1) and a second welding part (2) are relatively vibrated at high frequency, so that a first welding face located on the first welding part and a second welding face located on the second welding part collide at high frequency within a micro distance, which is 0.1-3 mm; after heat generated by collision makes the first welding face and/or the second welding face be melted, high-frequency vibration stops; and then, two workpieces to be welded are butt-jointed under a certain pressure in a vibration direction, and are pressed continuously and then released, so that welding is completed. In the method, by means of high-frequency vibration, welding surfaces perform high-speed and high-frequency collision and friction to generate heat, thereby realizing welding; the requirements for the appearance and structure of a product are low; no dust is generated; the welding quality is good; the energy consumption is low; and the precision is high.
