Abstract: A method which controls a heating power induced in a component in a generative manufacturing process wherein the heating power is induced by an induction heating system. The closed-loop control method is based on the concept of indirectly determining the previously unknown heating power which is actually induced in component. This is accomplished by the power losses, which substantially consist of waste heat to the cooling liquid and to the other surroundings, being deducted from the electrical power that is inserted into the induction heating system (specifically, the electrical power of the induction generator). The power losses are calculated, insofar as is possible; alternatively, they are also estimated.
