AWS A5.18 ER70S-6
TOKO ER70S-6(SG) is a mild steel welding wire: it is suitable for mild to medium strength steels. It is optimal for applications such as thin gauge steel and root passes, highly restive and low alloy steels, and can also be used for bridge and other structural steel applications. It is typically used in welding steel which contains manganese, which makes it difficult to weld. This wire is an all-position wire, but it should be used in short arc welding applications. It works best with CO2 or 75/25 Argon CO2 mixture and usually requires a voltage of more than 18 volts when welding with DCEP polarity.
ER70S-6, a general purpose welding wire for fabrication of mild steel. Contains more deoxidizers than ER70S-3. The additional deoxidizers also provide better wetting, giving a flatter bead shape and the capability of faster travel speeds. Usually used with 75/25 (argon/CO2) shielding gas or with higher contents of argon, such as 90/10. Can also be used with 100% CO2.
Copper-plated and layer wound. Especially well suited for sheet metal applications or structural plate steels that have moderate amounts of rust oil or mill scale on them
Common uses include construction work, farm implement fabrications, general shop applications with poor fit-up or rusty, oily plates, tanks, steel castings or forgings.
Typical applications:
• Repairs on a variety of mild and low alloy steel.
• Small diameter pipe and tubing • Sheet metal applications • Root pass pipe welding Key Features:
1. High levels of manganese and silicon deoxidizers tolerate medium to heavy mill scale surfaces
2. More puddle fluidity,excellent wetting action
3. Storage period: Vacuum packaging less than 1 Year, other packaging less than half year.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
