DEVICE FOR LASER HEAT STRENGTHENING OF THREADS AND METHOD FOR LASER HEAT STRENGTHENING OF THREADS Russian patent published in 2022 - IPC C21D9/22 C21D1/09 B23K26/73 B23K26/06 B23K26/352

Abstract RU 2777831 C1

FIELD: laser thermal hardening.

SUBSTANCE: inventions group relates to a device and method for laser thermal hardening of threads and can be used in machine-building, oil and other industries. The surface of the threaded groove is treated with a laser beam. The intensity profile of the laser beam is changed so that the intensity of laser radiation at its edges exceeds the intensity of laser radiation in its central region.

EFFECT: reducing the risk of reducing the thickness of the hardened layer obtained on the surface of the threaded groove during its processing with a laser beam.
