Welded steel pipe slag inclusions are slag that remains inside the weld. From a theoretical analysis, the main reasons for the slag inclusion in the submerged arc automatic welding seam are as follows: ①There are many inclusions in the raw materials (including base metal, welding wire, and flux); ②T

The defects that are easy to occur in the welding area of the spiral steel pipe include air holes, thermal cracks, and undercuts. Spiral steel pipe weld porosity not only affects the tightness of the pipe weld, causing pipeline leakage but also becomes a corrosion induction point, seriously reducing

At present, the most common pipe-cutting method for spiral steel pipe manufacturers is plasma cutting, which will generate a large amount of metal vapor, ozone, and nitrogen oxide smoke during cutting, which will seriously pollute the surrounding environment. The key to solving the soot problem is h
