Welding Wire for Welding Material

    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.


Specifications of Welding Wire:

1) Well antioxidant property

2) High exceptionally creep strength

3) Good corrosion resistance


Advantages of Welding Wire:

1) Improved toughness and ductility

2) Reduced porosity, slag and inclusions

3) Reduced susceptibility to hydrogen embrittlement, hot shortness and hot cracking

4) Consistent weld properties

Uses: It can be used for welding some key structures, such as pressure vessels, construction machinery, hoisting machinery, ships, mining machinery, etc.

1)The oil stains and rust on the weldments should be cleared away.

2) 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.

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.
