Ensuring the quality of laser-field welding requires monitoring not only the energy parameters of radiation and the intensity of the electrostatic field, but also the position of the focal spot. The calculation of the control channel for the laser radiation focus position during welding, which determines the parameters of the welded seam quality, is performed in the work. The active optoelectronic system parameters for the adjustment subsystem of the focus position relative to the seam with laser illumination of the seam are calculated, the model of the control channel is suggested taking into account the thermophysical phenomena occurring in the welding zone.
