[1] [2] [3] The RF power generator converts line power to high-frequency, high-voltage power for welding. Typical voltages are 1kVAC – 1.5kVAC at a frequency of 27.12 MHz. [1] The power needed for welding is based on the area of the weld, thickness, and the material. [2] The control unit is the system used for operating the machine.
The International Institute of Welding Technology IIW published the Guideline "Recommendations for the HFMI Treatment" [3] in October 2016. An overview of higher frequency hammers (HFMI) is presented, and recommendations for the correct application of the method and quantitative measurements for quality assurance the guideline provides the basis for measurements of HFMI improved welded joints ...
The apparatus used for induction welding processes includes a radio frequency power generator, a heating station, the work piece material, and a cooling system. The power generator comes in either the form of solid state or vacuum tube and is used to provide an alternating current of 230-340 V or a frequency of 50–60 Hz to the system.
It also has a plate and coil mill facility in India. In 2004, the company expanded its operations to include the production of high-frequency induction weld (HFIW) pipes and set up a new manufacturing facility in December of that year. [11] The company started its pipe coating operations through a partnership with Eupec Pipe Coatings Ltd in ...

High Frequency welding, also known as Dielectric Sealing or Radio Frequency (RF) Heat Sealing, is a very mature technology that has been around since the 1940s. High frequency electromagnetic waves in the range of radio frequencies can heat certain polymers up to soften the plastics for joining. Heated plastics under pressure weld together.
