The production process roughly includes the following steps:
1. Wire rod drawing: The raw material wire rod is drawn through a series of molds, gradually reducing the diameter to achieve the desired wire size.
2. Surface treatment: Remove impurities such as oxide scale and oil stains from the surface of the welding wire to improve welding quality.
3. Copper plating: Plating a layer of copper on the surface of the welding wire to increase conductivity and rust resistance.
ER70S-6 welding wire has a wide range of applications:
1. Mechanical manufacturing: used for welding various mechanical structures, such as frames, crane arms, etc.
2. Automotive industry: Welding of automotive components such as frames and bodies.
3. Construction industry: Welding of steel structures, such as steel structures for bridges and high-rise buildings.
4. Shipbuilding: Structural welding of ships.
5. Pressure vessel manufacturing: used to manufacture containers that can withstand a certain amount of pressure.
