Technical Field

[0002] Laser welding is one of the important applications of laser materials processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type; the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the laser pulse width, energy, peak power, and repetition frequency, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.
[0003] The wire feeding mechanism is a key device in welding equipment used for the stable delivery of welding wire. Its function is to control the welding current by adjusting the wire feeding speed. Its main components include a DC micro-motor, wire feeding rollers, and a reducer. Based on the feeding method, it is divided into three types: push-type, pull-type, and push-pull-type. The push-type is suitable for short distances (3-5 meters), the pull-type is suitable for medium to long distances (5-15 meters), and the push-pull type combines the advantages of both. The wire feeding rollers often adopt a double-drive roller design with a V-shaped or U-shaped surface to improve stability. During processing and production, to facilitate welding, the welding wire needs to be accurately delivered to the welding position, thus requiring a laser welding wire feeding device with a guiding structure.
