In recent years, there have been many directions of use in the field of fiber laser equipment, such as laser marking that is commonly used in many fields, laser cutting that is used in the machining field, and an increasing number of automated production lines using laser welding equipment.
The popularization of laser welding equipment in automated production lines has further improved production efficiency and product yield. So what role does the laser filter in the laser welding head, which is an important component, play?
The role of protecting window lenses in laser welding:
Laser welding equipment generates a large amount of smoke and other pollutants during the processing and welding process. Therefore, a high-quality laser protective window lens with anti pollution performance can protect the internal components of the equipment and work stably for a long time, reducing the maintenance cost of the laser equipment in the later stage.
The role of the vibrating mirror in laser welding:
In laser welding, the vibrating mirror projects the laser beam onto two mirrors (scanning mirrors), and the reflection angle of the mirrors is controlled by a computer. These two mirrors can scan along the X and Y axes respectively, thereby achieving the deflection of the laser beam. The laser focal point with a certain power density moves on the marking material as required, leaving permanent marks on the material surface. The focused spot can be circular or rectangular.
