Flux cored wire manufacturing

The manufacturing process of flux-cored wire is controlled very rigorously. Since the filler metal is derived from the steel sheet and the ingredients contained in the flux, the size and chemical composition before fabrication must be checked in detail to ensure quality.

As the internal space of the welding consumables is limited, the size of the flux particles becomes more and more important. The particles form a bird's nest-like joint and the components of the flux are not uniform.
