Laser cutting polarization degree
The laser cutting polarization degree describes the orientation of the electric field vector in the laser beam. It affects the absorption rate on metallic surfaces and is crucial for precise cuts.
Physical-Chemical Mechanism of Action
The laser cutting polarization degree refers to the orientation of the electric field vector in the laser beam. This vector can be aligned parallel or perpendicular to the surface of the metal plate being cut. The absorption rate of the laser at the surface depends on this orientation, as polarization affects the interaction between the laser light and the electrons in the material.
Metallurgical Relevance & Welding Risks
Correct polarization degree setting is crucial for contour-accurate laser cutting. An incorrect setting can lead to uneven material vaporization, missing cut edges, or even melting of the workpiece surface. This can impair cutting quality and lead to additional processing time and costs.
Workshop Practice & Action Guidelines
For precise laser cutting, the polarization degree should be set so that it is aligned parallel to the cut edge. This maximizes the absorption rate and minimizes melting of the material surface. For certain materials or special applications, perpendicular polarization may be required to achieve specific optical effects. It is important to follow the manufacturer's instructions for the exact polarization degree and, if necessary, determine the optimal setting through experiments.
