Comparison of Cleaning Effect Between Pulsed Laser And Continuous Laser
Feb 28, 2025
"Comparison of Cleaning Effect Between Pulsed Laser and Continuous Laser" introduce the cleaning performance of two types of lasers-pulsed and continuous-on surfaces. It compares their effectiveness in removing contaminants such as rust, paint, and dirt. The research finds that pulsed lasers tend to be more efficient at targeting specific areas with higher precision and less heat damage, while continuous lasers provide more uniform coverage and might be better for larger surface areas. The conclusion suggests that the choice between pulsed and continuous lasers depends on the cleaning task, with pulsed lasers being more suitable for intricate or detailed cleaning, and continuous lasers for broader applications.

Carbon steel surface rust removal |
Nanosecond pulse laser can effectively remove floating rust and black rust on the surface of corroded steel plate by optimizing parameters; continuous laser can remove floating rust on the surface of corroded steel plate, and the removal effect of black rust is poor. |

Both nanosecond pulse laser and continuous laser can remove thick paint layers. Due to the large heat input during continuous laser cleaning, the surface of the substrate is prone to discoloration after the paint layer is peeled off |
