![]() Our advantages is stable arc, little spatter, less smoke higher deposition efficiency excellent welding performance easy restrike. Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery etc. The wire is mainly suitable for welding in a field, structure, or working at height.ĭue to its self-shielding properties, the welding using this wire is highly portable.Flux Cored Arc Welding Wire (FCAW), is used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. This wire can be used for single-pass welding and multi-pass welding applications. E71T-11 Welding Wire UsesĮ71T-11 Welding Wire is used for welding carbon steel, mild steel, and low alloy steel materials. ![]() The necessary gases required to protect the weld pool are created by the burning of flux present in the welding wire covering. Does Welding Gas required for E71T-11 wire?Į71T-11 Welding Wire is a self-shielded cored wire which means it does not need an externally supplied welding shielding gas. The wire does not provide good arc characteristics when used with DCEP or AC Polarity and hence these polarities should be avoided. E71T-11 Welding Wire PolarityĮ71T-11 welding wire uses Straight Polarity (DCEN) i.e., Electrode Negative welding polarity. The wire is available in different welding diameters 0.030, 0.0350.045, and 0.068 inches. INNERSHIELD NR-211-MP welding wire specification is AWS A5.20. ![]() INNERSHIELD NR-211-MP is the Lincoln Welding wire brand name of the E71T-11 welding wire classification. ”11” is usability characteristics, here it is DCEN polarity, multipass weld, and self-shielded wire.”T” means Tubular flux cored welding wire.”7” is the tensile strength indicator multiplied by 10 is Ksi( here 70 Ksi minimum).E71T-11 equivalent CWB specification is W48-06 and the classification is E491T-11.ĮN ISO 17632-B equivalent of E71T-11 welding wire is T49ZT11. E71T-11 Welding Wire Mechanical Properties Properties Values Tensile Strength, Ksi (MPa) 70-95 (490- 670) Minimum Yield Strength, Ksi (MPa) 58 (390) Elongation, minimum 20 Toughness Not specified E71T-11 welding wire specificationsĮ71T-11 welding wire specifications are AWS A5.20 and SFA 5.20. Hence, it must be specified by the purchaser in case toughness requirements are applicable. The toughness requirements for the E71T-11 welding wire are not specified in AWS A5.20. E71T-11 has a tensile strength range of 70- 95 Ksi, a yield strength of a minimum of 58 Ksi. E71T-11 Welding Wire Chemical Compositions (Single values maximum permitted) Element C% Mn% Si% S% P% Cr% Ni% Mo% V% Al% Cu% % Composition 0.30 1.75 0.60 0.03 0.03 0.20 0.50 0.30 0.08 1.8 0.35 E71T-11 Welding Wire Mechanical PropertiesĮ71T-11 Welding Wire Mechanical Properties are given in the table below. Values stated as single is the maximum permitted. E71T-11 Welding Wire Chemical CompositionĮ71T-11 Welding Wire Chemical Compositions are shown in the below table. The weld deposits are highly aesthetic and slag removal is very easy with this wire. It can be used for single-pass and multipass welding. E71T-11 is a self-shielded cored wire used with straight polarity. E71T-11 Welding Wire is a flux-cored arc welding wire used in FCAW Welding.
