Application of High-Frequency Induction Heating for Brazing of Dissimilar Metals

Abstract:

The contribution deals with the initial design and numerical simulation of brazing process for components of solar collectors from copper-brass combined materials by the use of CuP7 brazing alloy with application of induction heating. The purpose of the contribution is to evaluate the suitability of designed inductor and its operation frequency for the given application on the basis of coupled numerical analysis of electro-magnetic and thermal fields by the ANSYS software. The attained results confirmed that using suggested arrangement of induction heating it is possible to ensure the brazing alloy melting and the development of a sound joint without undesirable overheating of brazed components or surface melting of brass flange. When increasing the frequency, the heating period is shorter but the maximum temperature of the brass component slightly increases.
