What is the role of laser filters in laser welding joints?

Laser filters – In recent years, there have been many laser blades in the field of fiber optic laser equipment. What is the role of laser blades in laser welding joints? In the field of laser marking and machining, inverted laser cutting has been used, and more and more automated production lines are using inverted laser welding equipment.

The popularization of laser welding equipment in automated production lines has further improved production efficiency and increased yield. So what role does the laser filter in the laser welding head, as an important component, play? Hanzhong Borisun Optics takes you to further understand the filters in laser welding heads.

The role of collimating and focusing lenses in laser welding:

The function of laser collimating lens and focusing lens is to project the laser beam output from the fiber laser onto the inverted processing surface through collimating lens and focusing lens. Due to the increasing use of high-power lasers, laser collimating lenses and laser focusing lenses require a certain high damage threshold.

The role of protecting window lenses in laser welding:

The laser welding equipment will produce a lot of smoke and other pollutants in the process of processing and welding, so a high-quality laser protection window lens with anti pollution performance can protect the internal components of the equipment, and can work stably for a long time, which can reduce the later maintenance cost of the laser equipment.

The role of the galvanometer in laser welding:

In laser welding, the galvanometer incident the laser beam onto two mirrors (scanning mirrors), and the reflection angle of the mirrors is controlled by calculation. These two mirrors can scan along the X and Y axes respectively to achieve the deflection of the laser beam, allowing the laser focal point with a certain power density to move according to the required requirements on the marking material, leaving permanent marks on the material surface. The focused spot can be circular or rectangular.
