Anti-corrosion spiral steel pipes are made of low-carbon structural steel rolled into tube blanks according to relative spiral angles, and then the pipe seams are welded together. They are also called spiral steel pipes or spiral welded pipes. Anti-corrosion spiral steel pipe manufacturers will produce slag inclusions during the production process. , what is the reason?
The first thing to consider is whether it is caused by a large amount of debris contained in the raw materials. The raw materials include base metal, welding wire, flux, etc., which are all possible causes of slag inclusion; and then the selected welding process parameters are inappropriate, which is not conducive to the formation of slag. Emerge, resulting in the occurrence of slag inclusions; incomplete cleaning between layers during multi-layer welding is also the cause of slag inclusions in the production of anti-corrosion spiral steel pipes.
