Purpose: of this study was to investigate of temperature fields distribution during GMA brazing of solar collectors. Design/methodology/approach: IR-pictures were recorded with 50 Hz frequency. After recording, thermovision pictures were analyzed in Irbis software module. This software permit to matching recording parameters, identification of temperature values in arbitrary picture points, assign temperature profiles. Findings: distribution of temperature fields in the GMA brazed joints in the function of GMA brazing parameters and brazing techniques was established. Research limitations/implications: basic information about distribution of temperature fields in the GMA brazed joints is the background of the researches of GMA brazing parameters providing highest quality joints. Practical implications: results of this paper are the data of the temperature fields distribution during GMA brazing of solar collectors joints recorded by IR-camera. This data are important to set an optimal brazing parameters. Originality/value: the researches were provided using newest filler material for GMA brazing of solar collectors parts using IR recording equipment.
