Comparison of CW & Pulsed laser cleaning machine
|
CW Laser Cleaning Machine |
Pulse Laser Cleaning Machine |
|
|
Principle |
Stable continuous laser output, relying on thermal effects (vaporization/expansion) |
High peak power pulse output, thermal+mechanical effects (Impact crushing) |
|
Typical Laser Power Range |
1500W-6000W |
100W-1000W |
|
Cleaning Speed |
Fast (suitable for large areas, such as ㎡/h level, cleaning width usually ≥300mm) |
Slow (high-precision control, such as cm²/min level, cleaning width usually ≤200mm) |
|
Cleaning Effect |
Minor damage, heat effect is large, may damage and deform the surface of heat-sensitive materials. |
No damage, heat effect is small, safely removes contaminants without damaging the substrate |
|
Material Adaptability |
Suitable for heat-resistant metals (steel, cast iron, etc.) |
Suitable for metals including heat-sensitive and highly reflective metal, and some non-metal. |
|
Use and Maintenance |
Easy to use. Optical protective lenses are replaced regularly. No chemical consumables. Auxiliary gas (dry air) is required. |
Easy to use. Optical protective lenses are non-consumable and can be used for a long time. No chemical consumables are required. Auxiliary gas (dry air) is required. |
|
Core Advantages |
High Efficiency |
No damage, wide range of applicable materials |
|
otential Disadvantages |
Risk of heat damage, not suitable for highly reflective materials and wood |
Slow speed |
|
Typical Application Cases |
Ship rust removal Large vehicle body rust removal Pre- and post-welding treatment Steel structure surface rust removal |
Wood cleaning Aircraft skin stripping Car body and auto parts cleaning Cultural relics cleaning Mold cleaning |
