AWS A5.18 ER70S-6
It is suitable for the welding of carbon steel and low alloy steel, such as Gr.50, and so on.
This GMAW wire is for Rm 500MPa level carbon steel with shield gas of CO2 or M21. Small spatter, beautiful appearance, high deposition efficiency and small weld metal porosity sensibility. All positions is suitable.
1. The rust, oil, water and other impurities of the weld area must be removed before welding.
2. The mechanical properties of all weld metal be decided by heat input, normally the small heat input will better than larger one.
