Cleveland - Lincoln Electric has updated its Metalshield® line of metal-cored wires with H4 diffusible hydrogen MC-6 and MC-706. The products now feature less than 4mL of diffusible hydrogen per 100g of weld metal to reduce the risk of porosity and hydrogen-induced cracking in weld deposits. In addition, Metalshield® MC-706 has been tested and approved for American Welding Society (AWS) D1.8 seismic welding applications. Both are designed for arc welding applications and offer low spatter levels, deoxidizing arc action and high travel speeds.
Metalshield MC-6 (E70C-6M H4) is a mild steel, metal-cored wire for all position welding that provides optimal performance in fast-follow, high travel speed applications. The wire tolerates moderate amounts of surface contaminants and features optimal wetting action, even at low voltages. MC-6’s low spatter levels minimize post-weld cleaning, especially when used with Rapid-Arc® Waveform Control Technology® found in Power Wave® equipment.
Metalshield MC-706 (E70C-6M H4) is a mild steel, metal-cored wire for all position welding that is designed for high deposition, high travel speed applications. Metalshield MC-706 offers enhanced silicon island management to minimize slag and cleanup time. The wire tolerates higher amounts of surface contaminants and produces welds with Charpy V-notch toughness down to -40? degrees F (-40? C).
Another added feature of Metalshield MC-706 is AWS D1.8 seismic welding approval. Two diameters are tested to meet lot waiver requirements and test results are available online. To view of download the AWS D1.8 Certificate of Conformance, visit www.lincolnelectric.com/D1.8.
These products are available to purchase in three different diameters and have several packaging options to choose from. Contact your local distributor or Lincoln Electric sales representative.
