Spoolarc® 75 is a copper-coated 1% nickel solid wire for carbon steel and low alloy welding applications using either the MIG/Gas Metal Arc Welding (GMAW) or Submerged Arc Welding (SAW) Processes. Spoolarc® 75 produces a deposit that meets the weathering requirements of AWS D1.1 and D1.5 and is designed to weld weathering steels and/or where improved low temperature impact toughness is specified. Shielding gas choices for Spoolarc® 75 are Ar/CO2 mixtures containing a minimum of 75% Ar or the 98% Ar/2% O2. Spoolarc® 75 is used for bridge and structural welding.
