Electrothermal technologies, in particular induction heating, can play an important role on improving performance and quality in brazing and soldering metal joints. Induction heating, in comparison to other industrial heat treatments for brazing processes that are traditionally based on open flames, allows to induce heat directly inside the workpiece, reducing process time and costs, with fully controllable and repeatable processes. The development and design of induction heating processes for brazing homogeneous or heterogeneous metal joints can be carried out by means of finite elements models and simulations. Numerical methods allow for an optimal design of the process in order to fulfil the technical requirements of brazing alloys by setting process recipes, inductor shapes and power requirements, taking into account all the constraints related to the integration of the induction heating system on production lines. In this paper, some applications of induction brazing technology, considering different joint geometries, base metals and brazing alloys, will be described with an in depth focus on inductor design and process fine tuning by means of multi-physics finite element modelling and simulations. The whole process of finite element simulation will be described, starting from geometry definition, models of relevant properties of joint materials and brazing alloys, by resorting to electromagnetic steady state sinusoidal solutions coupled with time dependant thermal model. Simulation results will be compared with experimental data obtained from field tests conducted on metal joints brazed using induction heating technologies and the same inductors and process recipes defined during the simulation stage.
