The high frequency (HF) welding process, also known as radio frequency (RF) welding, combines materials by supplying them with high frequency energy in the form of an electromagnetic field (27.12 MHz) that is produced between two metal electrodes.
HF welding must be accompanied by a certain pressure on the material surfaces to be joined, and this is also how HF welding machines are designed.
Welding or HF welding is based on the unique properties of the welded material, which generates heat in a rapidly changing electric field, the so-called dielectric heating of the welded material.
This means that only some materials can be welded using this technique, including, of course, the materials used in the production of hydro BANKS , in which the dynamic electric field causes oscillation of the polar molecules (molecules) of the material.
Depending on their geometry and dipole moment, these molecules convert part of this oscillating motion into thermal energy and cause the material to heat up and weld.
