Induction heating alias DAWELLING
Induction heating is a modern technology suitable for heating a conductive material (usually metal) by eddy currents induced in it by an electromagnetic field. It is a non-contact method of heating materials that absorb energy from an alternating magnetic field generated by an inductor (induction coil).
The actual working part of the device is the inductor and this is where the energy is transferred from the power unit and the working head to the heated material.
The basic source of energy is the alternating current from the mains (50 Hz), which is adjusted in the power supply – inverter to the desired frequency of induction heating between 10 – 400 kHz. Lower frequencies are used for large objects for deeper magnetic penetration, higher frequencies for thin-walled and small objects.
Induction heating is used to heat various materials and shapes before or after welding, straightening steel profiles, soldering, annealing and melting metal materials in various industrial and repair applications.
