[0002] With the continuous improvement of the requirements for precision machining in modern manufacturing, the demand for welding technology in the field of mold processing is also increasing day by day. As an efficient and precise welding method, laser spot welding technology is widely used in the connection and repair of metal materials. Traditional mold welding methods usually rely on mechanical clamping and manual adjustment, resulting in a cumbersome operation process, large influence of human factors on welding quality, and in a high-temperature working environment, welders are exposed to high temperature, strong light and waste gas, which is easy to cause physical harm.

[0003] At present, there are already some automated laser spot welding devices on the market.

If these waste gases are not effectively treated, they will not only pose a threat to the health of operators, but may also pollute the environment. At the same time, strong light, ultraviolet rays and infrared rays are generated during welding, and operators are prone to visual damage during the welding process, especially when directly looking at the welding point, the risk is greater when the protective measures are insufficient.
