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.

Welding Engineers NZ Ltd is also the Authorised Distributor for Nippon Steel Corporation's Speciality Steels, including Advanced Coastal Weathering Steels NAW-TEN and CORSPACE, and High Performance Bridge Steels, SBHS Series.

 NSWE's welding materials are developed in concert with their steel products to meet the developing needs of their customers worldwide, this is a strong factor in the premium quality of the Nippon Steel welding consumables and also very important when matching filler metals to speciality steels with specific chemical compositions.

Unlike many wire manufacturers, NSWE have access to the very best base metal at a cost effective price, in this case the virgin 'A' grade steel produced by NIPPON STEEL.

NIPPON  wires are filled with flux longitudinally rather than vertically to ensure an even spread of flux ingredients, dried, sealed and double copper coated.

They have typically have a very low hydrogen content and are virtually impervious to moisture during shipping and storage, so minimal risk of cold cracking and perfect for use when low diffusible hydrogen is particularly important.

Superb Japanese engineering ensures the wires are perfectly round in cross-section so there is no spiralling or pig-tailing when run.

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 shipbuiling and structures requiring impact testing at -40 deg., SF-3A is often the recommended fluxcored 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.
