Both continuous-wave and pulsed lasers could remove the paint, rust, oil, film, coating, dust from the material surface. With the same power, the efficiency of pulsed laser cleaning is much higher than that of the CW(Continuous-Wave) one. Meanwhile, the pulsed laser works better on heat control to prevent the substrate from being over-temperature and avoid micro-melting.
Continuous-wave lasers are advantageous in pricing. But the heat inputs of high power continuous wave laser are higher and the degree of damage to the substrate increases.
Therefore, there is a fundamental difference in terms of application between CW and pulsed fiber laser for cleaning. For applications that require high precision, strict substrate temperature control, and very small damage to the substrate, such as molds, we should choose a pulsed fiber laser cleaner machine.
For some large steel sheets and pipes, due to the large size and fast heat dissipation, the requirements of substrate damage control are not high, we can choose continuous wave fiber lasers.
