Single layer steel strip lap type. During production, the powder is filled in the pre processed U-shaped steel strip, and then the two sides of the steel strip are lapped together at the upper end of the U-shaped steel strip with a mold. At this time, the powder has been coated in the steel strip, and then the core wire is compacted with a finishing mold.

The cross section of domestic outsourcing core wire is circular. Rectangle. Square, etc. There are four main production methods of core clad wire in China:

① Single layer steel strip lap type. During production, the powder is filled in the pre processed U-shaped steel strip, and then the two sides of the steel strip are lapped together at the upper end of the U-shaped steel strip with a mold. At this time, the powder has been coated in the steel strip, and then the core wire is compacted with a finishing mold.

② Double layer steel strip lap type. This method is the same as ① except that the steel strip is coated with two layers. This kind of core wire is used less.

③ Steel strip welding sealing. During production, the powder is filled in the steel strip that has been pre processed into a U-shape, and then the steel strip filled with powder is closed into a tube and the joint is twisted and compressed.

④ The steel strip is folded and sealed. The process is to pack the powder into the pre processed U-shaped steel strip, and then fold and twist the two ends together by rolling. Use the mold to finish the core wire.

At present, the fourth method is mainly used in production.
