In the field of laser cleaning, fiber lasers have become the best choice for laser cleaning light sources with higher reliability, stability and flexibility. As the two major components of fiber lasers, continuous fiber lasers and pulsed fiber lasers occupy the market leading positions in macroscopic material processing and precision material processing, respectively.
For emerging laser cleaning applications, there are different sounds about whether continuous lasers or pulsed lasers should be used. Two types of laser cleaning equipment using pulsed and continuous lasers have also appeared on the market. Many industrial end users do not know how to choose when choosing.
1. Comparison of Cleaning Result
After pulsed light cleaning, the paint layer on the surface of the workpiece is completely removed, and the surface of the workpiece appears metallic white, and there is almost no damage to the substrate of the workpiece. After using continuous light cleaning, the paint layer on the surface of the workpiece was completely removed, but the surface of the workpiece appeared gray-black, and the substrate of the workpiece also appeared micro-melting. Therefore, continuous light is more likely to cause damage to the substrate than pulsed light.
2. Comparison of Price
Continuous lasers have advantages in price, and high-power lasers can be used to make up for the efficiency gap with pulsed lasers. However, high-power CW lasers have greater heat input and damage to the substrate will increase. Therefore, the two have a fundamental difference in application scenarios. High precision requires strict control of the heating of the substrate, and application scenarios that require non-destructive substrates, such as molds, are recommended to choose pulsed lasers. For some large steel structures, pipelines, etc., due to their large size and fast heat dissipation and low requirements for substrate damage, continuous lasers can be selected.
