Introduction: JC-29Ni1 is a kind of low-alloy steel self-shielded flux-cored welding wire, which needs no shielding gas. The deposited metal contains 0.80%~1.10%Ni. It has excellent low temperature toughness and good crack-resistance. It has high deposition efficiency. The arc has strong penetration power with spurting appearance. It has easy operation, beautiful appearance of weld and good slag detachability. DCSP (Direct Current Straight Polarity). Suitable for all-position welding. Due to the fast concreting speed of slags, it is especially suitable for vertical downward welding. It can be used for welding thick plates and key structures with high rigidity.

Uses: Used for making welds requiring high toughness and needing nickel. Especially suitable for site welding on API X52 to X70 oil and gas pipelines highly requiring low temperature toughness. Also used for automatic and semi-automatic welding on general steel, atmospheric corrosion-resistant steel and high strength steel, such as oil and gas pipelines, ocean platforms, storage tanks, etc.
