In the field of laser cleaning, continuous laser cleaning machines and pulsed laser cleaning machines are the two most common technical approaches. Each has its own strengths and limitations, making them suitable for different cleaning requirements. This article compares them in terms of working principle, application scenarios, and cleaning effect, to help you make the best choice.
1. Working Principle Comparison
Continuous Laser Cleaning Machine
-
Emits a continuous laser beam onto the workpiece surface
-
Primarily relies on sustained thermal effect to evaporate or decompose contaminants such as paint or grease
Pulsed Laser Cleaning Machine
-
Emits high-energy pulsed laser with extremely high peak power
-
Relies on instantaneous high energy density to produce strong laser ablation or shockwave effect, directly stripping or fracturing layers such as oxide, coatings, or weld slag
2. Application Scenario Comparison
Continuous Laser Cleaning Machine
-
Best for large-area, light-to-medium contamination (dust, grease, thin paint layers)
-
Suitable for flat or large workpieces such as steel plates, pipelines, and large structural components
Pulsed Laser Cleaning Machine
-
Best for stubborn, hard, or tightly bonded contamination (thick oxide layers, dense coatings, weld slag, rust)
-
Suitable for precision parts, complex shapes, or heat-sensitive materials (molds, engine parts, electronic components, artwork restoration)
3. Cleaning Effect & Substrate Impact
Continuous
-
Higher cleaning efficiency for large-area jobs and cost-effective for bulk tasks
-
Continuous heat input can cause overheating, micro-melting, or deformation in thin-walled or low thermal conductivity materials
Pulsed
-
Pulse parameters (energy, frequency, pulse width) can be precisely controlled, achieving a “cold processing” effect that limits heat diffusion into the substrate
-
Avoids micro-melting, large heat-affected zones, or deformation, making it ideal for precision and heat-sensitive materials
-
While single-point efficiency may be lower than continuous type, its performance for stubborn contamination is superior and more controllable
