FIELD: process engineering.
SUBSTANCE: proposed method relates to metal-working industry, particularly, to working rail head by laser. Laser beam is located at angles to axis of symmetry of machined rail, feed direction and beam rotational axis. Note here that laser power is fed in pulses with duration governed by angle of laser beam contact with processed material and laser beam rotation speed.
EFFECT: shaping rail head by concave shaping line formed in laser beam rotation.
