Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding device. Background Art

[0002] Laser welding is a highly efficient and precise welding method using a laser welding device that uses a high energy density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, 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] Although laser welding has significant effects in terms of quality and precision compared to other welding methods, it is easy to generate radiation during the laser welding process. At the same time, a large amount of smoke and harmful gases will be generated during the laser welding process. There are also protective covers on the market to shield smoke, harmful gases or radiation, but most of them require the product to be processed to be transported to the welding work area first, and then the protective cover is manually pulled down to shield the smoke and harmful gases. Although this method can protect against smoke, harmful gases or radiation to a certain extent, the overall protection effect is poor, and the overall production efficiency is low, so it needs to be improved on this basis.
