Ausztenites korrózióálló acélok lézersugaras vágása

Abstract

Nowadays, laser technology has become an essential part of our lives. The great advantage of lasers used in materials processing is that they provide very precise, quick machining and low heat input. However, all machining requires unique parameters. These parameters are for example: Power, wavelength, cutting speed and focus line distance. Using optical microscopes and electron microscopes to examine the cutting surfaces of the CO 2 laser, we can see that the cut has high quality surface (cutting 3,25 mm thick plates), but holes made with a solid-state laser have micro-cracks on the inner side. These cracks are not acceptable to the customers.
