Reasons for slag inclusion during the production of anti-corrosion spiral steel pipes.
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.
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.
