Selection analysis of continuous laser and pulsed laser cleaning


At present, there are pulsed laser cleaners and continuous laser cleaners on the market, both of which can remove dirt on the surface of the substrate. The only difference is that the pulsed laser cleaner uses pulsed laser emission. The continuous laser cleaning machine uses a continuous laser transmitter. The pulsed laser cleaner can achieve zero damage to the substrate after cleaning the dirt, which is suitable for cleaning products with high requirements on the surface of the substrate; while the continuous laser cleaner has almost all damage to the substrate and is suitable for large-area cleaning, such as Steel plate rust removal, paint removal, shipyard rust removal, etc.

Equipment characteristics:

◆Non-contact cleaning, without damaging the base material of the parts. To

◆Does not need any chemical cleaning fluid, low noise, safe and green. To

◆Easy to operate, just power on, and it can be hand-held or cooperated with a manipulator to realize automatic cleaning. To

◆The cleaning efficiency is very high, saving time. To

◆The first investment, no consumables, the equipment is simple and easy to operate and maintain, saving costs. To

Differences between two models

Both continuous lasers and pulsed lasers can remove paint on the surface of the material to achieve a cleaning effect.

Under the same power conditions, the cleaning efficiency of pulsed lasers is much higher than that of continuous lasers. At the same time, pulsed lasers can better control the heat input to prevent excessive substrate temperature or micro-melting.

CW 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, there is a fundamental difference between the two in application scenarios. High precision requires strict control of the heating of the substrate, and application scenarios that require the substrate to be non-destructive, such as molds, should be 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.
