According to the search results, the following are the recommended parameter settings for laser cleaners when cleaning stainless steel weld spots:
Laser power: according to the experimental results, the use of 65 W hand-held laser cleaning device can achieve better cleaning effect.
Spot Coincidence Ratio: A recommended spot coincidence ratio of 1.2 helps to ensure that the weld spot area is adequately covered.
Pulse width: The pulse width is recommended to be set between 30 and 240 ns to meet different cleaning needs.
Pulse energy: The pulse energy is recommended to be set between 0.1 and 0.8 mJ, and the optimal energy is 0.1 to 0.2 mJ, so that the welding spot can be effectively removed without damage to the substrate.
Power density: The power density has a significant impact on the cleaning efficiency, when the power density reaches about 1.4E + 08 w / cm2, the cleaning efficiency is no longer improved.
Therefore, it is recommended that the power density be set within this range to ensure cleaning efficiency and effectiveness.
Spot overlap rate: spot overlap rate is also very important to the cleaning effect, the experiment shows that the rust clean and the substrate does not appear obvious oxidation overlap rate range of about 20% ~ 50%
Therefore, it is recommended to set the spot overlap rate in this range.
Spot size and fill spacing: spot size and fill spacing need to be reasonably determined according to the specific cleaning spot size to avoid uneven shading after cleaning
These parameter settings are based on the recommendations of experiments and professional guides and may need to be fine-tuned for specific equipment and material characteristics in practice.
