Product Details
The welding principle of high-frequency welded steel pipe is to use the skin effect and proximity effect of high-frequency current. The skin effect concentrates the current on the conductor surface, while the proximity effect controls the current flow path. Through these two effects, high-frequency current quickly heats the edge of steel pipe to a molten state, and then welding is realized by extrusion. This method has the advantages of high welding speed, high weld quality and small heat affected zone.
