Main Differences: Continuous and Pulsed Laser Cleaners !

1. Output power intensity

Generally speaking, the greater the power of the laser cleaning machine, the higher the cleaning efficiency. The power range of the pulse laser cleaning machine is 200 watts to 1000 watts, and the power of the continuous laser cleaning machine is 1000 watts to 3000 watts. In this way, the continuous laser cleaning machine has more advantages in cleaning efficiency.

However, it should be noted that during the cleaning process with too high power, the substrate temperature will be too high, causing more obvious damage to the surface of the material.

2. Cleaning depth

For stubborn dirt, the cleaning effect of the pulse laser cleaning machine will be more thorough.

Due to the working principle of the pulse laser cleaning machine, the energy of the pulse laser is more concentrated and the spot is smaller, so it can deeply clean the dirt accumulated for a long time. For example, oxides, rust, coatings, paint oil stains, etc.

3. Cleaning effect

After the pulse laser cleaning machine cleans the material, there is almost no damage to the bottom of the substrate. Not only that, after cleaning the material, it can also be very close to the original base color of the material. After the continuous laser cleaning machine is finished, slight white marks will be left on the surface of the metal material. Although the cleaning is very good, its appearance may be better than that of the pulse laser cleaning machine.

4 .Different materials are suitable for cleaning

We used a 1000W pulsed laser cleaning machine and a 1500W continuous laser cleaning machine to test rust and oil stains.

For light rust, both pulse and continuous lasers can easily remove it. Both have good cleaning speed and effect. However, for thicker rust and larger areas, continuous laser can provide better cleaning results.

For oil stains, pulse laser cleaning is more thorough and effective, and it hardly damages the material. However, continuous laser is less effective in removing oil stains and may leave some black residue on the surface.

If you need to clean a thicker rust layer, it is recommended to use a continuous laser cleaning machine. If you need to clean oil stains and thinner rust layers, pulse laser is a better choice.

5. Effect of heat on materials

The pulse laser cleaning machine uses short pulses for cleaning, so the laser will not always irradiate the surface of the material, and the heat accumulation is minimal. It is suitable for processing heat-sensitive materials.

During the long cleaning process of the continuous laser cleaning machine, due to the large light cutting power, the accumulated heat is large, which may cause thermal effects on the cleaning materials.

6. Light uniformity

The laser of the pulse laser cleaning machine is continuously output at very short intervals, with a high peak power, while the laser output of the continuous laser cleaning machine is stable and continuous, so its beam uniformity will be better.

7. Price and cost

The cost of the pulse laser cleaning machine is higher because it requires a more complex control system to generate high peak power laser pulses, coupled with a high-precision optical system and cooling device, the overall price is higher than that of ordinary continuous laser systems.

The price of continuous laser cleaning machines is relatively cheap, especially the continuous laser system with mature technology, because the output power is stable and relatively simple, the production and maintenance costs are low.
