Hardening of Large-Size Details Using Scanning Radiation of Optical Fiber Laser with Programming Power Change
The analysis of the scanning laser processing process. The results of the calculation of the temperature field arising during laser quenching with constant power and with a change in the laser radiation power depending on the position of the laser beam during its relative displacement are presented. The possibility of using software-variable laser power in the scanning process is shown. The results obtained were used in the development of a laser technological complex for the hardening of functionally loaded surfaces of large-sized MLS‑20–3DF-A large parts. The use of laser hardening of large-sized parts made it possible to improve the quality of products, to ensure an increase in the lifetime of mine dump trucks, to reduce the cost of products, to create additional production capacity.
