Wuxi Gotele Metal Corporation has been doing business for welding wire for decades. Its products features good quality and durability.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that is usually stronger than the base material.
Pressure may also be used in conjunction with heat, or by itself, to produce a weld.
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 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.
Packaging of Welding Wire:
Wuxi Gotele Metalare 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.
Many different energy sources can be used for welding, including a gas flame,
an electric arc, a laser, an electron beam, friction, and ultrasound.
While often an industrial process, welding may be performed in many different environments,
including in open air, under water, and in outer space.
Welding is a hazardous undertaking and precautions are required to avoid burns,
electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to intense ultraviolet radiation.
