SMENCO has added Nippon Steel Group’s Seamless Flux Cored Wires to its welding consumables portfolio, strengthening its offering of high-quality solutions for demanding industrial applications.
Developed by Nippon Steel Welding & Engineering, one of the leading welding manufacturers in Japan, these welding wires feature a seamless construction that helps prevent moisture absorption and maintains stable welding performance. This design supports low diffusible hydrogen levels and contributes to reliable weld quality, even in challenging environments.
Seamless wire technology provides several operational advantages compared with conventional open-seam flux-cored wires. The fully sealed wire structure helps protect the internal flux from moisture exposure, improving storage stability and reducing the risk of hydrogen-related weld defects.
Seamless Technology for Reliable Welding Performance
Nippon Steel Group’s seamless wires are designed to support stable arc characteristics, reduced spatter generation and consistent bead appearance. Many products in the range are engineered to maintain excellent impact toughness at low temperatures, making them suitable for applications where structural integrity is critical.
These characteristics make the wires well suited for industries such as:
- Shipbuilding
- Offshore structures
- Structural steel fabrication
- Heavy equipment manufacturing
By combining advanced welding wire design with rigorous manufacturing standards, Nippon Steel Group’s seamless wire technology supports consistent performance in environments where weld quality and reliability are essential.
Nippon Steel Group’s Seamless Wire Range Available at SMENCO
SMENCO now offers several Nippon Steel Group’s seamless wire products designed for a variety of welding requirements:
SM-3MA
A seamless metal cored arc welding wire designed for use with Ar + 20% CO₂ shielding gas. It supports root pass welding in all positions in the short-circuit arc range and flat, horizontal and fillet welds in the spray arc range, while delivering excellent impact toughness down to -40°C.
SF-3A
A rutile type seamless flux cored arc welding wire developed for welding shipbuilding grade E steel. Weld metal demonstrates excellent toughness in low temperature ranges between -20°C and -40°C, with strong crack resistance and all-position weldability.
SM-47A
