Luoyang Ship Material Research Institute (China) holds DNV Type Approval certificate TAW0000596 for SRSF40Mn / SJ206, issued 2022-10-12 by DNV SE. In welding practice, a wire/flux pairing is approved as a set, so the wire and flux are treated together. The register classifies the product as a wire/flux combination within the category Welding Consumables, and the certificate is valid until 2027-10-11.
Wire and flux combinations of this kind are typically used in submerged-arc welding of steel plate and sections in shipyard fabrication, where the flux covers the arc and the wire is fed continuously along the joint.
