High-Frequency Welding - an overview | ScienceDirect Topics

High frequency welding or radio-frequency (RF) welding or dielectric welding uses high frequency (13–100 MHz) electromagnetic energy to generate heat in polar materials, resulting in melting and weld formation after cooling. A high intensity radio signal is used to impart increased molecular motion in two similar or dissimilar polymers. This causes the materials to rise in temperature ...

What is HF/RF welding? | Forsstrom

High Frequency (HF) or Radio Frequency (RF) welding is the joining of materials by supplying HF energy in the form of an electromagnetic field (27.12 MHz) and pressure to the material surfaces to be joined. A generator produces the energy.  The tool used to supply the energy is called an electrode.

Advantages and disadvantages of high frequency welding

High-frequency welding mainly uses the skin effect and proximity effect of high-frequency current, so that the current is highly concentrated on the edge to be welded, so that it can be heated to the soldering temperature (1130-1350’C) in one hundredth of a second. Then, pressure welding is performed under the action of a squeeze roller. This welding method has a series of advantages: the ...

HIGH FREQUENCY WELDING - Balacchi

High Frequency welding is the process of fusing materials together by applying high frequency energy to the area to be joined. The energy produces localised heating of the materials, causing them to soften and melt, thus allowing their molecules to intermingle. After a period of cooling, the materials become joined together at the point of the weld. The resulting weld can be as strong as the ...

Advantages and Disadvantages of High Frequency Welding ...

High-frequency welding machine welding uses the unique skin effect and proximity effect of high-frequency current, so that the welding current is concentrated on the surface of the contact, the temperature of the surface joint surface rises rapidly, and the surface to be welded is heated to a plastic state of melting or near melting.

Selecting a welding frequency - The FABRICATOR

High-frequency contact and induction welding processes have been used in welded tube production for more than 50 years with little attention paid to the welding frequency. Traditional vacuum-tube-type welders operated at frequencies between 300 and 400 kilohertz (kHz). First-generation solid-state welders, which were introduced in the early 1990s, generally had frequencies that were much lower ...
