Flux Core Mild Steel MIG Wire

Description

E71T-1, features lower spatter and fume emissions than conventional products in this class. This electrode 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. E71T-1 is used where a minimum tensile strength of 70,000 psi is required in the deposited weE71T-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 applications. Decreasing amounts of CO2 in the argon-CO2 mixture will increase manganese and silicon in the deposit and may improve the impact properties. These electrodes are designed for single and multiple pass welding. The larger diameters (usually 5/64″ (2.0 mm) and larger) are used for welding in the flat position and for horizontal fillets. The smaller diameters (usually 1/16″ (1.6 mm) and smaller) are used for welding in all positions. E71T-1 is characterized by a spray transfer, low spatter loss, flat to slightly convex bead configuration, and a moderate volume of slag which completely covers the weld bead. E71T-1 electrodes have a rutile base slag.

Incomparable weldability in all positions makes E71T-1 a good choice for general plate fabrication, structural steel welding, shipbuilding, steel fabrication and any instance where lower fume and spatter emissions are required. The reduced spatter is especially attractive in those operations where painting is performed immediately after welding
