Weldcote Metals E7T-1 Features Lower Spatter And Fume Emissions Than Conventional Products In This Class. E71T-1 Is Intended For Single And Multiple Pass Welding Of Carbon And Certain Low Alloy Steels In All Positions, Particularly In The Overhead And Vertical Up Positions. Weldcote Metals E71T-1 Is Used Where A Minimum Tensile Strength Of 70,000 Psi Is Required In The Deposited Weld Metal. Weldcote Metals E71T-1 Electrodes Are Classified With Co2 Shielding Gas By This Specification However, Gas Mixtures, Of Argon-Co2 Are Also Used To Improve Usability, Especially For Out Of Position Application. Decreasing Amounts Of Co2 In The Argon-Co2 Mixture Will Increase Manganese And Silicon In The Deposit And May Improve The Impact Properties. The Larger Diameters Are Used For Welding In The Flat Position And For Horizontal Fillets. The Smaller Diameters Are Used For Welding In All Positions. E71T-1 Is Characterized By A Spray Transfer, Low Spatter Loss, Flat To Slightly Convex Bead Configuration With A Moderate Volume Of Slag Which Completely Covers The Weld Bead E71T-1 Electrodes Have A Rutile Base Slag.
