Causes of slag inclusion in the production of anti-corrosion spiral steel pipes

Anti-corrosion
spiral steel pipe is made of low-carbon structural steel rolled into tube blanks according to the relative helical angle, and then the pipe seams are welded together, also called
spiral steel pipe or spiral welded pipe. Anti-corrosion
spiral steel pipe manufacturers will produce slag inclusions during the production process. For what reason?
The first thing to consider is whether it is caused by the inclusion of more impurities in the raw materials. The raw materials include base metal, welding wire, flux, etc., which are all possible causes of slag inclusion; then the selected welding process parameters are improper, which is not conducive to the formation of slag. Floating results in the appearance of slag inclusion; during multi-layer welding, the interlayer is not cleaned properly, which is also the cause of slag inclusion in the production of anti-corrosion
spiral steel pipes.
