The laser welding machine, also known as a laser engraving machine, is a type of laser material processing machine, categorized into laser mold welding machines, automatic laser welding machines, laser spot welders, and fiber-optic transmission laser welding machines based on their working principles. It utilizes high-energy laser pulses to locally heat materials within a small area. The energy from the laser radiation diffuses into the material's interior through thermal conduction, causing it to melt and form a specific molten pool for welding purposes.

Does laser welding equipment pose any harm to humans during the welding process? I believe most people are very concerned about this issue.

In fact, the laser of a laser welding machine is a form of light energy that is emitted, characterized by its high intensity. The laser emitted from the source generally does not come into contact or is not visible, and can be considered to cause no physical harm; however, a laser welding machine can induce ionizing radiation and stimulated emission during the welding process. This induced radiation can have a significant impact on the eyes and body. Although the laser beam is very small, prolonged observation of the sparks produced by the cutting can be harmful to the eyes and cause a stinging sensation. Therefore, when observing light sources for extended periods, operators must wear protective radiation goggles.
