Nippon Flux Cored and Metal Cored Wires
Welding Engineers NZ Ltd is the Authorised Distributor of flux and metal cored welding wires produced by NIPPON STEEL WELDING & ENGINEERING., LTD. (NSWE), in New Zealand and Australia. NSWE is a subsidiary company of NIPPON STEEL CORPORATION (NSC), the largest steel manufacturer in Japan and one of the top three in the world.
7 Reasons to Choose NSWE
- Very low hydrogen content in the weld metal
- Superior targeting and wire feeding properties
- Very good and consistent mechanical properties
- Less downtime and increased productivity
- Excellent conductivity and stable, spatter-free arc
- Reduced contact tip consumption
- Longer shelf life with less storage preconditions
Hydrogen content
The biggest advantage with NSWE seamless FCW wires is their extremely low hydrogen content, achieved with heat treatment as an important part of NSWE’s innovative production method, ICF (In-line Continuous Filling). This technique prevents postproduction atmospheric moisture absorption as well. In comparison, conventional folded type flux cored wires have a seam which allows moisture to penetrate the flux, resulting in a constant increase in hydrogen pickup when exposed to moisture in the atmosphere.
Copper coating
The seamless design also enables the wire to be copper coated. The copper coating and exact symmetrical cross-sectional shape achieved by the ICF production engineering results in excellent wire feeding properties, tip abrasion resistance and accurate, stable targeting. NSWE seamless wires are therefore ideal for mechanized/robotic welding purposes as well as manual/semi-automated welding.
Perhaps best known of the NIPPON wires sold by Welding Engineers in New Zealand is the SF-1E, a seismic grade, seamless flux cored wire with very low hydrogen content.
In Australia, where the use of mixed gases is more common, SF-1A is the equivalent. For shipbuilding and structures requiring impact testing at -40 deg., SF-3A is often the recommended flux cored wire.
Latest technology is represented by SM-3A metal cored wire. For extremely efficient welding with maximum deposition and travel speed, minimal to nil spatter, low fumes AND the capability to be welded in all positions, this wire is outstanding. Productivity gains of 30% are not only possible but can be achieved easily by all welders. Also ideal for robotic welding.
Welding Engineers NZ Ltd represents Nippon Steel Corporation in the area of speciality steels, including advanced coastal weathering steels and special high-performance bridge steels. As a small, seismically active nation with a large coastline, New Zealand has much in common with Japan and continues to benefit from Japanese advanced research, technology and meticulous engineering and manufacture in the construction field.
