Key Specifications/Special Features:
Standard: GB/T ER50-6/ DIN SG2/ JIS YGW12,AWS ER70S-6/ BS A18/ EN G3Si1
Description: Welding wire ER70S-6 (SG2) is a copper coated low alloy steel wire shielded by 100% CO2 with all position welding.
The wire has a very good welding performance and higher efficiency in welding. The weld metal on the base metal.
It has low blowhole sensitivity.
Application: Welding wire ER70S-6(SG2) is mainly used for butt and fillet welding structures made by shipping steels and low alloy steels. Such as ships, containers, vehicles, engineering & construction machinery, bridges and so on.
Available size: 0.8mm/0.9mm/1.0mm/1.2mm/1.6mm
