Factory Supply Laser Hardening/Quenching Machine Laser Heat Treatment Equipment

During the laser heat treatment process, after the laser beam stops scanning, observe the surface state of the laser quenched strip with the naked eye or a low-power magnifying glass at any time, and macroscopically judge the surface quality of the quenched strip. Microscopic analysis should take the cross-sectional area of the quenched strip as the observation surface, and use a metallographic microscope to detect the depth (mm) and width (mm) of the quenched hardening layer at a magnification of 100 times. The depth of laser hardening layer is generally below 1mm. The microstructure of laser quenched steel materials is mainly martensite. The microhardness method should be used to detect the hardness of the quenched layer, and the load value should be selected based on the properties, thickness, and depth of the quenched layer of the sample.

By analyzing the material characteristics, usage conditions, service conditions, and other factors of quenched parts, the technical conditions and product quality requirements are clarified, and then the laser quenching hardening model is selected and the laser quenching process parameters are determined. At the same time, the operability, production efficiency, and economic benefits of the process should also be considered. The laser beam mode is divided into multimode beam, low-order mode beam, and fundamental mode beam, which are generally used for laser heat treatment.
