The laser welding system consists of a laser source, optical fiber for transmission, and collimation/focusing optics such as collimating lenses or galvanometer mirrors. The laser beam emitted from the fiber is divergent and needs to be collimated by collimating lenses to transform it into a parallel beam. It then passes through focusing lenses to achieve a focused state (using the magnifying glass effect). During the laser welding process, key parameters for adjustment include power, speed, defocus distance, and shielding gas.

The principle of focusing adjustment is as follows:
The energy distribution of the laser beam is not uniform. Typically, it forms a funnel shape around the focusing lens. At the waist of the beam, the energy is most concentrated and strongest. To ensure efficient processing and quality, it's essential to locate the focal plane and adjust the defocus amount accordingly for product fabrication. Without establishing the focal plane, subsequent parameter adjustments cannot proceed effectively. Therefore, identifying the focal plane is fundamental in mastering laser technology.

Many products require peripheral accessories to form a perfect and high-performance product. Similarly, peripheral accessories are also needed to form a masterpiece. What are the common peripheral accessories of laser equipment? Let me introduce a few below.
