If this defect occurs, it will have a great impact on the equipment. The metal oxide is melted in the V-shaped mouth. If it is found that the edge of the steel strip of the pipe welding machine has a melting speed less than the melting speed, the melting speed is also relatively fast. At the vertex of the V-shaped mouth, a narrow sector containing molten metal magazines is formed. These molten gold

Genus and metal oxides, which cannot be discharged normally under extrusion after normal use, form an inclusion band at the same time. The weld of the pipe welding machine will crack after flattening, if inclusions are found in the position of the weld fracture. The inclusion and the fibrous fracture of the weld are compared, the fracture is very flat, no metal luster. This type of defect may also give a chain-like "oxide" and is not a very defect.
Under normal couples, burrs or rust will fall, and the bridge formed before the apex will cause a short circuit in the pipe welding machine, thus causing the current to jump.
