Welding Engineers is the Authorised Distributor for Nippon Steel Welding & Engineering welding products, including the most advanced metal cored wires, in Australia and New Zealand. We are also the authorised distributor for Kobelco and Chosun metal cored welding wires in New Zealand.

Welding Engineers introduced metal cored wires to the New Zealand market in 2009 and have the experience and technical expertise to ensure you will make the most of the advantages metal cored wires can bring to your welding operation.

Metal cored wires combine the high deposition rates of flux cored wires with the high efficiencies of solid wires to improve productivity.

Metal cored wires run harder and faster with a lower heat input than both flux cored and solid wires.

One of the biggest benefits of metal cored wires is the reduction in pre- and post-weld activities. Due to the flux components, they can weld through mill scale, dirt and debris, and have a greater tolerance of cold steels. 

A premium quality metal-cored wire like KOBE MX-A70C6LF or NIPPON SM-3A runs much cleaner and smoother than solid wire - which means minimal to no spatter, lower fume levels, less wear and tear on tips, liners, drive rollers, etc, leading to savings in other consumable costs as well.

MIG welding with metal cored wires means an easier to operate and more forgiving arc, lower number of welding defects, better tolerance against surface contaminations and weld preparation on typical basic and synergic welding machines and keeps this advantage over solid wires while welding with controlled waveforms (pulse, SpeedArc, SpeedUp, Power Wave, or similar programs). 

Particular care needs to be taken when changing to fully synergic machines with the ability to run wires faster and harder, as solid wires are often then pushed outside the manufacturer's specifications and weld integrity is not maintained.

Metal cored wires do cost slightly more on a per kg basis than solid or flux cored wires. However, in almost all applications, labour accounts for approximately 85% of the total cost of the welding work and the significant productivity increase gained by switching to metal-cored wire will well out-weigh the increase in the filler metal cost. 

 Faster, more efficient, better quality welding will decrease the largest cost component of your work – Labour.

Nippon Steel's SM-3A is a copper coated, seamless, Seismic Grade 3 metal cored wire with exceptional arc stability and smooth running.

Diffusible hydrogen content is as low as solid wire, excellent crack resistance.

Exceptional for a metal cored wire in that its specifications are such that it can be used in all positions for single pass welding. 

So Nippon SM-3A can give maximum deposition, speed, low heat input and you can go from horizontal to vertical welding without stopping, with the right gear.

Combine with customized speed process programme on a Lorch MicorMIG welding machine for up to 30% gain in speed.
