Material: copper coated


    Application: Bridges, Ships, Steel constructure, Machinery production

Shanghai Metal Corporation has been doing business for welding wire for decades. 

Its products features good quality and durability. 


Gas-shielded Solid
Introduction: JQ.MG80-G is a kind of high strength gas-shielded welding wire. 

The mixed gas Ar+20% CO2 can be used as shielding gas. It has soft arc, 

stable burning and fewer spatters. The bead has higher impact toughness.


Uses: Suitable for welding high strength structures with tensile strength of 

790MPa. It can be used for welding some key structures, such as pressure 

vessels, construction machinery, hoisting machinery, ships, mining machinery, etc.

Instructions:
1) The impurity content in the shielding gas should be strictly controlled to guarantee the purity of gas.
2) When welding, the gas flow rate is generally 20 - 25L/min.
3. The extension elongation should be 15~25mm.

Packaging of Welding Wire

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

1) Shanghai Metal Standard

2) Customization


Applications of Welding Wire:

Can used to welding ship building steel (A , B, D, E, A36, D36, E36) and 

equivalent mild steel or 550Mpa grade mild alloy steel, such as container 

buildings, bridge building, machinery manufacturing, railway construction, 

pressure vessels for semi-auto or automatic gas shielded welding and

general welding purposes, etc.
