High-frequency welding two important components
The HF welding machine consists of two components: the HF generator and the welding press.
The HF generator
The high-frequency generator develops the HF field at a frequency of 27.12 MHz and supplies a power, depending on the application, of 500 Watt to 60 kW. Up to 2 kW one uses semiconductors in the generators, but for higher powers one still uses an oscillator tube.
The HF welding press
The material to be welded is laid on or in the welding press. In the welding press there are two electrodes present with a double function: transfer the HF energy to the material and press the two layers of material together.
Usually the welding press table serves as bottom electrode. This table is earthed and can be touched without any problem. Under the pressure head of the welding press the top electrode is applied in the shape of the required seal/weld. The HF generator supplies the HF energy to this top electrode (simply referred to as ‘electrode’).
There are many different HF welding machines available, which have been optimized for various applications.
important factors for high frequency welding
The four most importent factors / process parameters influence High frequency welding are
Electrical power
Pressure applied
Welding time
Cooling time
Finding the optimal process parameters will depend on your specific equipment,
the materials involved and the specific geometries including thickness’ and area to be welded.
