DUAL SHIELD II 70T-12H4
Dual Shield II 70T-12H4 is an all-position, low hydrogen flux cored wire that provides excellent low temperature toughness. This flux cored wire provides a smooth arc and low spatter levels, excellent for construction, fabrication, offshore and railcar applications.
Features
Each of the new Dual Shield II H4 wires is an all-position flux cored wire that provides excellent low temperature toughness in both the as welded and/or stress relieved conditions (as applicable) when used with 75% Ar/25% CO2. Each can produce diffusible hydrogen levels of < 4mL/100g over a wide range of welding parameters. Dual Shield II 70T-12H4 also provides the smooth arc and low spatter levels characteristic of other Dual Shield II wires. Dual Shield II 70T-12H4 can be used in construction, heavy equipment fabrication, offshore oil components, shipbuilding, and railcar. Weld metal analysis is similar to E7018 & E7018-1 low hydrogen covered electrodes
