| 摘要 |
The invention relates to an induction head for welding multilayer stacks for printed circuits and the like, wherein an inductor core associated with an excitation inductance is cooled by air or another gaseous fluid, which circulates in a path provided in the induction head. A second inductor core cooperates with the first one to guide a magnetic flux to at least one junction area of a multilayer stack interposed between the cores: the cooling fluid laps the junction area of the multilayer stack, thus facilitating the detachment of the head at the end of the welding process. |
