Laser Cleaning Technology: A Comprehensive Guide To The Green Cleaning Revolution | Laserchina

Laser cleaning technology has emerged as a pivotal innovation in industrial manufacturing, offering a green and efficient alternative to traditional cleaning methods. Since its inception in the 1960s, laser cleaning has been recognized as one of the 21st century’s most promising technologies, with potential applications spanning across various sectors, from industrial maintenance to cultural heritage preservation. In this blog post, we’ll explore how LASERCHINA’s laser cleaning machines are leading the charge in this technological evolution, providing eco-friendly solutions with minimal substrate damage, high flexibility, and exceptional cleaning results.

Understanding the Mechanism of Laser Cleaning

Laser cleaning operates on the principle of irradiating a high-energy, high-repetition-rate laser beam onto the surface of a material. The contaminants absorb the energy and, as a result, the bond between the stain and the substrate weakens, causing the grime to detach from the surface. LASERCHINA engineers have delved deep into the cleaning mechanism, evaluating and improving cleaning effects and expanding the range of cleanable materials, which now include metals, alloys, glass, and various composite materials.

Advantages of Laser Cleaning Machines

Laser cleaning technology stands out for its numerous benefits. The most notable advantages include its eco-friendliness, as it eliminates the need for chemical agents, thus preventing liquid waste pollution. Moreover, laser cleaning is known for its minimal impact on substrates, high degree of flexibility allowing for automation, excellent cleaning quality through the selection of different wavelengths and processing parameters, and high cleaning efficiency due to advanced scanning technology.

Applications and Developments in Laser Cleaning

LASERCHINA engineers conducted comprehensive tests using aluminum cover plates and 1mm thick aluminum nails, examining various parameters such as laser speed, single-point energy, frequency, pulse width, peak power, and defocus amount. The results were impressive: a weld depth of 0.9mm, weld width of 1.18mm, a CPK of 1.7, and a welding speed of ≥14mm/s. These tests confirmed the solution’s capability to produce welds without explosions, pits, pinholes, or cracks, achieving full, porosity-free weld pools with no surface explosions or blackening.
