High-frequency welding taking solid resistance heat as energy. During welding, the resistance heat generated in the workpiece by the high-frequency current is used to heat the surface layer of the workpiece welding area to melt, and then the upsetting force is applied to realize the bonding of metals. High-frequency welding is a specialized welding method. The special equipment should be equipped according to the product. It has high productivity, welding speed up to 30m/min. High-frequency welding mainly used to weld longitudinal straight seam pipe or spiral pipe.
