LASER HARDENING USE FEATURES ON STEEL C45

2019-01-01, Zaicevs, Edgars, Teirumnieks, N., Lazov, Lyubomir

The paper investigates and describes laser hardening of steels, types of lasers, important parameters of laser hardening, as well as steels that are suitable for laser hardening process. The laser hardening process of steel C45 samples is described, the analysis of the results is described and the result is summarized. The results of the experiments show that laser hardening is capable of meeting the relevant requirements and quality parameters in steel C45 hardening.

RESEARCH OF CARBON FIBER MATERIAL LASERCUT OPTIMIZATION

2019, Pīgožnis, Kārlis, Lazov, Lyubomir, Teirumnieks, Edmunds, Okunevs, A.

The report considers the possibility of using laser technology for cutting products from carbon fiber. The study uses a fiber laser with a wavelength of 1080 ±10nm. The dependences of the width b of the cutting lines on power density q and processing speed v are considered. As a result of experimental studies, power density and speed parameters were optimized for high-quality cutting of the carbon fiber.
