FIELD: laser processing methods; laser welding systems.

SUBSTANCE: group of inventions relates to a laser processing method (versions), a non-volatile computer-readable data carrier and a laser welding system. The laser processing parameters associated with the laser radiation source and the laser movement parameters associated with the laser beam movement provided by the laser processing scanning head are received. The laser processing parameters and the laser movement parameters are used in the course of laser processing, which is performed by a laser processing system including a laser source and a laser processing scanning head. The distribution of laser energy is set at a plurality of points within the movement of the laser beam based on at least one of the obtained laser processing parameters and the parameters of the laser movement. A visual image of the distribution of laser energy is displayed at a plurality of points within the movement of the laser beam. The visual image of the laser energy distribution is used to detect and correct failures during laser processing and/or predict the actual distribution of laser energy during laser processing. The technical result consists in ensuring efficient distribution of laser energy, in particular in the field of welding, by moving the beam along the workpiece in accordance with different scanning patterns in the near field or "wobble" patterns, since different patterns ultimately provide different distribution of laser energy on the surface of the workpiece depending on various processing parameters and beam displacement parameters, while existing systems do not allow the user to visualize (for example, before starting laser processing) the different distribution of laser energy, which with a high degree of probability follows from these parameters, and, thus, do not allow him to make an informed decision regarding the pattern and/ or parameters most suitable for a particular task.

EFFECT: ensuring efficient distribution of laser energy.
