Laser Thermohardening and Die Recovery (Including Large-Sized ones) Using a Mobile Laser Robot DOI: 10.22184/1993-7296.FRos.2024.18.3.196.204
The article presents a mobile laser robot MEL‑3.0 for laser thermohardening and build-up of a wide range of products, equipped with a diode laser. The robot was developed by TermoLazer LLC. The examples of stamping die thermohardening and their restoration at some enterprises are given. The capabilities of a mobile robotic laser tool and some issues of its application in relation to the large-sized items, including directly at the operating site, are discussed.

Increasing the Operational Life of Chisel Steels in the Case of Laser Hardening DOI: 10.22184/1993-7296.FRos.2024.18.3.206.215
Mechanical Engineering Research Institute of the Russian Academy of Sciences, Moscow, Russia
The paper examines the results of micrographic and tribotechnical tests of chisel steel X12 in a friction pair with the through hardened steel 40X when lubricated with the industrial oil I20. It is shown that the use of lateral oscillations of the laser beam significantly increases the processing productivity. It has been established that the high-quality laser thermohardening of sample edges is possible only by applying lateral oscillations of the beam when exposed to the continuous laser radiation. In the case of optimal laser processing conditions and hardening of 50% of the sample friction surface, the wear resistance properties have been increased by 1.6 times compared to the through hardening.
