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 Wire Benefits

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). 

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.

Very low hydrogen content gives excellent crack resistance.

SM-3A can be used in all positions for single pass welding and multi-layer welding using dip transfer mode or similar.

So using SM-3A gives maximum deposition, speed, low heat input and, with the right welding machine, can switch from horizontal to vertical welding without stopping. 

Big productivity and safety advantage when you don't have to turn a beam or workpiece, or switch to a different wire to continue.

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

Kobe MX100T is a special, all-positional, metal cored wire for two reasons; it can be run as low as 50 amps and it can be used for welding root passes without the need for ceramic backing.

Better deposition rate, faster, and less filler metal is used than TIG or electrode welding similar work.

This makes it the ideal wire for welding thin sheets of mild steel and root runs; welding at low temperatures means no distortion or burn through.

MX100T can be used for welding root passes without ceramic backing, for example in pipeline construction, which also contributes to significant gains in productivity when compared to the TIG or stick electrode process.
