High Frequency Welding is resistance welding, in which the heat is produced by the current flow induced by a high-frequency electromagnetic field. Also known as radio-frequency welding
Straight Welding in producing pipe is straight type of ERW. ERW stands for Electric Resistance welded pipe. A plate rolled to become a pipe and welded using Electric Resistance Welding process.
