Description

Technical Field

[0001] The utility model relates to the field of laser welding equipment, in particular to a positioning and protective laser welding equipment. Background Art

[0002] The working principle of laser welding equipment mainly includes the following steps:

[0003] First, the laser welding head generates a high-energy laser beam; this laser beam is highly directional, monochromatic and coherent; then, the laser beam is accurately guided to the welding area through a transmission system, such as optical fiber or reflector; when the laser beam is irradiated to the surface of the workpiece to be welded, the laser energy will be absorbed by the workpiece; due to the high concentration of laser energy, the surface of the workpiece will quickly heat up and melt in a very short time; with the movement of the laser beam or the relative movement of the workpiece, the molten metal forms a strong weld after cooling; in this process, the precise control system will adjust and control the laser power, pulse frequency, scanning speed and other parameters to meet different welding requirements and material characteristics;

[0004] The laser welding head produces a high-energy laser beam. If workers look directly at it, it will cause retinal burns, resulting in decreased vision, blurred vision, visual field defects, etc. In severe cases, it can lead to blindness; this damage is often irreversible.
