Introduction: It is a kind of gas-shielded flux-cored welding wire for low-carbon steel and 490MPa high strength steel. JQ.YJ501-1 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. Suitable for downhand welding and horizontal welding. 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, good crack-resistance and stable and reliable inherent quality.

Uses: Used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery, 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.
