For induction soldering a secondary spool, the soldering inductor, is connected with a high-frequency generator. The alternating current flow in the inductor induces a magnetic field. Eddy currents in the soldering joint caused by that magnetic field effect the heating up to the soldering temperature. In order to avoid a warming up of the inductor, cooling water is pumped through the hollow spool wire. Induction soldering makes a large energy transfer possible. A further advantage of this procedure is the low expense for maintenance.
Range of Applications
Induction is used for applications with high energy transfer, for soldering parts with different thermics capacity and for contacts embedded in plastics.
