The video will talk the "Pierce" in fiber laser cutting and perforation in laser cutting. There are two videos "this video and next video".
Our first question is why we need “Pierce”. Perforation quality can easily lead to cutting and processing good or not, especially in thick metal cutting. In general fiber laser cutting, most of the time, we won’t start cutting from the edge of metal plate. So we need to punch a small hole in the plate and then cut from it.
