Continuous laser VS pulsed laser, how to choose laser cleaning Machine ?
For emerging laser cleaning applications, there are different voices about whether to use continuous laser or pulsed laser. There are also two types of laser cleaning equipment using pulsed and continuous lasers in the market. Many industrial end users do not know when they choose how to choose. This article compares the laser cleaning applications of continuous and pulsed lasers, and analyzes their characteristics and applicable application scenarios.
Both continuous lasers and pulsed lasers can remove paint on the surface of materials to achieve the effect of cleaning.
Under the same power conditions, the cleaning efficiency of pulsed laser is much higher than that of continuous laser. At the same time, pulsed laser can better control the heat input to prevent the substrate temperature from being too high or micro-melting.
CW lasers have an advantage in price, and can make up for the gap in efficiency with pulsed lasers by using high-power lasers, but high-power CW lasers have greater heat input and increased damage to the substrate.
Therefore, there are fundamental differences between the two in application scenarios. With high precision, it is necessary to strictly control the heating of the substrate, and the application scenarios that require the substrate to be non-destructive, such as molds, should choose a pulsed laser. For some large steel structures, pipes, etc., due to the large volume and fast heat dissipation, the requirements for damage to the substrate are not high, and continuous lasers can be selected.
