Radio frequency welding or (high frequency welding) is the process of bonding together materials through the use of electromagnetic energy. Two electrodes create an oscillating electric field that begins to shift and move polar molecules within the materials in order to orient themselves in accordance with the electromagnetic field. The movement of these molecules releases energy in the form of heat. When enough energy is applied, the molecules begin to melt and bond to one another. No external heat is applied. The weld is completed by applying pressure to the bonded area, ensuring a successful seal.
