The principle of electric welding machine laser on the surface of the aircraft

The principle of electric welding machine laser on the surface of the aircraft:

The process of pulsed Nd:YAG electric welding machine laser depends on the characteristics of the light pulse generated by the laser, based on the optical physical reaction caused by the interaction between the high intensity beam, the short pulse laser and the polluted layer. Its physical principle can be summarized as follows:

1. The light beam emitted by the laser is absorbed by the contaminated layer on the surface to be treated.

2. The absorption of large energy forms a rapidly expanding plasma (highly ionized and unstable gas), resulting in shock waves.

3. The shock wave causes pollutants to be broken into pieces and removed.

4. The width of the light pulse must be short enough to avoid the accumulation of heat that would damage the treated surface.

5. The experiment shows that plasma is produced on the metal surface when there is oxide on it. Wuhan Ruifeng photoelectric laser is one of the earliest production of laser equipment enterprises, with more than 10 years of experience in research and development,

in technology and integration of leading peer enterprises. Since its establishment, the company always pays attention to the research and

development of laser technology and the development needs of customers, and is committed to providing perfect material processing solutions for each enterprise.

Plasma is produced only if the energy density is above a threshold, which depends on the layer of contamination or oxide being removed.

This threshold effect is important for effective cleaning while ensuring the safety of the substrate. There is a second threshold for plasma.
