The contribution deals with the design of a progressive metallurgical joining of the solar collector parts by brazing. The main aim was to replace flame brazing by the more advantageous technology of brazing using high-frequency induction heating. New equipment and the induction coil of a suitable shape were designed for the joint manufacturing. Based on the numerical simulations of electromagnetic and temperature fields, the basic parameters of induction brazing were suggested in order to achieve the desired temperature distribution at the spot of the future joint. To check the quality of the brazed joints, a leak test, optical microscopy and EDX microanalysis were used to study the area of the brazed joints interface. Impact of brazing time and power supply on brazeability of Al alloys components by means of the AlSi12 braze were assessed.
