Abstract
A procedure is proposed for calibration of an optical system designed for evaluation of temperature field distribution in the welding zone. Calibration allows compensation of all the inherent and setting errors of sensor block components.
Keywords: arc welding, automation, temperature field, welding zone, multispectrum pyrometry, video cameras calibration, standard, conjugated points
