The Laser Cleaning Principle :
The process of pulsed Nd: YAG laser cleaning depends on the characteristics of the optical pulses generated by the laser, based on the photophysical reactions caused by the interaction between high intensity beams, short pulse lasers, and pollution layers. The physical principles can be summarized as follows:
1.The beam emitted by the laser source is absorbed by the pollution layer on the surface to be treated.
2.The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), generating shock waves.
3.Shock waves cause pollutants to become fragments and be removed.
4.The width of the light pulse must be short enough to avoid heat accumulation that can damage the treated surface.
5.Experiments have shown that when there are oxides on the metal surface, plasma is generated on the metal surface.
Plasma is only generated when the energy density is above the threshold, which depends on the removed pollution layer or oxide layer. This threshold effect is crucial for effective cleaning while ensuring the safety of the substrate material. There is a second threshold for the appearance of plasma. If the energy density exceeds this threshold, the substrate material will be destroyed. To achieve effective cleaning while ensuring the safety of the substrate material, it is necessary to adjust the laser parameters according to the situation, so that the energy density of the light pulse is strictly between two thresholds
Each laser pulse removes a certain thickness of contamination layer. If the pollution layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the degree of surface contamination. An important result generated by two thresholds is the self-control of cleaning. The light pulse with an energy density higher than the first threshold will continue to remove pollutants until it reaches the substrate material. However, because its energy density is lower than the failure threshold of the substrate material, the substrate will not be damaged.
There are various cleaning methods in the traditional cleaning industry, mostly using chemical agents and mechanical methods for cleaning.
After environmental protection regulations are becoming increasingly strict and people's awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning will become fewer and fewer.
The Handheld Welding Gun Three-In-One Laser Head is a perfect combination of high-tech laser welding,cleaning,cutting technology and adopt advanced touch screen digital control system.
The laser welding gun is equipped with an advanced fiber laser control system and internal structure, and its head weight is only 0.7Kg, making it easy to control and portable.
What’s more, this handheld laser welder comes with a Three In One Laser welding head that allows users to adjust its laser welding area from 0.5~5mm freely, laser cleaning area from 0.5~50mm freely, easy to switch different working mode between laser welding, laser cleaning, laser cutting. It is absolutely the best choice for those who require excellent laser welding,cleaning,cutting performance.
The Three In One Handheld Welding Head is exclusively designed and manufactured by HanWei Laser.It combines three functions: laser welding, laser cleaning, laser cutting functions into a single one handheld laser head unit :
1.Laser Welding Function :
The Three-In-One Handheld Laser Head welding function is same as special handheld laser welding head. Just in the control system have one more function for switching Laser Cleaning mode.
2.Switching cleaning mode from welding mode just need to click CLEANING button in touch screen monitor. Then tore down the front welding part of handheld welding head, After that replace the special focus lens.
3.Switching cutting mode from welding mode, just need to replace a special cutting nozzle.
All of switching process in Three-In-One Handheld laser head is simple and easy to operate.
