High-frequency (HF) welding is a welding process in which the heat source used to melt the joining surfaces is obtained from HF alternating current (ac) resistance heating. This article discusses the advantages and disadvantages and applications of HF welding. It describes the equipment used for HF welding and the safety aspects to be considered during welding. The article concludes with a discussion on inspection and quality control.
