What is the effect of inclusions in the pipe welding machine?

If such a defect occurs, it will have a great impact on the equipment. The metal oxide is melted in the V-shaped port. If the edge of the strip of the pipe welding machine is found to be less than the melting rate, the melting speed is relatively fast, at V. The apex of the mouth, and then a narrow sector containing a molten metal magazine, these molten gold
Genus and metal oxides, which are not normally discharged after extrusion after normal use, form an inclusion band. The weld of the pipe welder will crack after being crushed, if inclusions are found at the location of the weld fracture. The inclusions and the fibrous fractures of the weld are compared, and the fracture is very flat and has no metallic luster. Such defects may also give a chain of "oxides" and are not very defective.
Under the general couple, the burr or rust will fall to the bridge formed before the apex, which will cause the short circuit of the welding machine to cause the current to jump.
