Abstract:
1. An induction brazing method for parts able to have a complex shape, comprising: defining a heating heat cycle comprising phases of temperature rise, leveling and cooling depending on a material to be brazed; depositing a brazing seam on a joint plan between the parts to be brazed; exerting a substantially uniform pressure onto the parts to be brazed; making available a heat mapping of the material to be brazed taking variations of emissivity coefficient for such material into account during a cycle for a heating homogenization check; and then regulating such heat cycle by a closed servo loop from a sight in one point being heat representative by further taking variations of the emissivity coefficient of the material in such point into account and by a localized heat through a shape induction closest to the joint plan of the parts to be brazed, on which the brazing seam has been deposited, wherein an inductor presents globally a shape of the joint plan of the parts to be brazed.
