AWS A5.29 E71T8-Ni1-J
Flux Cored Wire E71T8-Ni1-J
Flux Cored Wire AWS A5.29 E71T8-Ni1-J is a low-alloy steel self-shielded flux-cored welding wire, which needs no shielding gas. It has excellent low temperature toughness, high deposition efficiency with 0.8%-1.10% Ni in the deposited metal. The arc has strong penetration power with spurting appearance. It has easy operation, beautiful appearance of weld and good slag detachability. Direct Current Straight Polarity (DCSP). It is suitable for all-position welding. Due to the fast concreting speed of slag, it is especially suitable for vertical downward welding.
