What is the role of penetration testing in steel plate cutting

Penetration detection function refers to that when the laser is cutting the steel plate for drilling and puncture, the high-power pulse laser acts on the steel plate to form a starting hole. When the cutting steel plate is not completely penetrated, there is a certain difference in the degree of laser reflection from the cutting steel plate. The cutting head of the laser cutting equipment has a photosensitive element that can monitor the intensity of reflected light in real time to identify whether it is penetrated, and provide the control system in time. The whole puncture control time is a dynamic process. In this way, the time wasted in laser puncture can be effectively avoided, the cutting quality of steel plate can be improved, and the working efficiency can be improved.

There are many factors that affect the cutting quality. The interaction between laser and cutting steel plate is very sensitive to various external conditions. In order to obtain the best cutting quality, each process parameter in the laser cutting process is limited to a very narrow range. For laser cutting, how to find the best cutting parameter under different cutting conditions and keep it stable in the whole cutting process is particularly important.
