Introduction: JQ.YJ601Ni2-1 is a kind of titania type CO2 gas-shielded flux-cored welding wire. It has excellent welding performance, soft and stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. All-position welding. It has high welding efficiency. The weld metal has been given toughening treatment by microelements, so it has excellent low temperature toughness above -30℃ and good crack-resistance.

Uses: Used for welding structures made of 590MPa low-alloy high strength steel. Widely used for welding some key structures like hoisting machinery, bridges, storage tanks, steel-frame structures, etc.

Instructions:
1.The oil stains and rust on the weldments should be cleared away.
2.When welding, the gas flow rate is generally 20～25L/min.
3.When welding with flux-cored welding wires, the extension elongation should be 15～25mm.
4.The humidity of the welding wire storerooms should be preserved below 60%.
5.It is not suitable for non-vacuum-packed welding wires to be stored for more than half a year, and it is not suitable for vacuum-packed welding wires to be stored for more than a year.
