Product Description


High Frequency Welded process is to use the skin effect to concentrated on the steel object surface, use proximity effects to control the position and the power of the high-frequency electric current flow path. Since the speed is very high, the contacted plate edge could be heated and melted inshore time, then extruded through the docking process.


The high-frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small-caliber steel tubes.
