Metal Cored Welding Wire offers faster, more efficient, better quality welding that will decrease the largest cost component of your work – Labour.
Please note the American Welding Society withdrew the A.36 Classification in 2021 but both old and new classifications may coexist for some time. There have also been changes to some EN ISO classification designations, which may not be correct on manufacturer data sheets as yet. The updated and corrected classification specifications can be found on the top of each wire product page. If you have any queries, please contact us.
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 and cost savings that 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. They can be run harder and faster with a lower heat input than both flux cored and solid wires.
Using metal cored wires will reduce 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 than welding with solid wires.
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 out-weigh the increase in the filler metal cost.
