Cavitylike defects on the laser cut surface

Reporter: Shulyatyev V.

Defects like craters on a surface of laser cut at laser-oxygen cutting of low-carbon steel are experimentally investigated. Depth and diameter of craters, quantity of craters per surface area unit are measured. It is established that the maximum quantity of craters is observed at an optimum cutting speed when the roughness of the surface is minimum. The qualitative explanation of the obtained results is offered.
