The laser hardening operation is intended to replace nitriding technologies with a depth of 0.3–0.4 mm and cementation with a layer depth of 1.0–1.1 mm. The objectives of the work were to determine the influence of the defocusing of a fibre laser beam on the depth and width of the laser hardening zones. According to the regression equations, calculations are performed and compared with the results of the experiment.
