Small science of ER70S-6 copper-plated welding wire

Material grade: ER70S-6

Standard: ASME

It belongs to copper-plated low-alloy steel gas shielded welding wire. It uses C02 or argon-rich shielding gas for welding. It has excellent welding process performance, stable arc combustion, less spatter, beautiful weld shape, and low sensitivity to weld metal pores. The position welding process is good. It can be suitable for a wide welding current range.

Uses: Suitable for single-pass and multi-pass welding of carbon steel and 500MPa low-alloy steel (such as welding of vehicles, bridges, buildings, mechanical structures, etc.), and can also be used for high-speed welding of thin plates and pipes

ER70S-6 is alloy wire steel, mainly used for gas shielded welding. Gas shielded welding is arc welding that uses external gas as an arc medium and protects the arc and the welding zone. Gas shielded solid welding is a high-quality, efficient and energy-saving welding method. It is widely used in heavy machinery, construction machinery, ships, boilers, vehicles, etc. in my country. The manufacturing industry has been more and more widely used. In recent years, China's gas shielded welding has developed rapidly, and the amount of gas shielded welding wire is increasing. The market demand for welding steel wire rods for processing gas shielded welding wire is in the news rapid increase. ER70S-6 is a commonly used gas shielded welding wire in foreign countries. The chemical composition is controlled according to the requirements of the American Welding Society standard AWSA5.18. The welding wire has good arc stability and high weld performance during welding, and is widely used abroad.
