AWS ER100S-G is a specification for a type of steel filler wire used in welding. The "ER" stands for "electrode or rod," the "100" indicates the minimum tensile strength of the weld metal in thousands of pounds per square inch (psi), and the "S" indicates that it is a solid wire. The "G" at the end of the specification indicates that the filler wire is used for the gas metal arc welding (GMAW) process.
The wire is AWS ER100S-G high tensile strength wire with a tensile strength of 730MPa and yield strength of 660MPa, which is widely used for welding scraper chains and hydraulic supports of mining machinery.
AWS ER100S-G can be used to weld high-strength steel structures up to 730 MPa, such as construction machinery, cranes, bridges, pipelines, ships, pressure vessels, etc.
(1) This product is the 730MPa grade high tensile strength wire, it has very good mechanical properties.
(2) With the mixed shielding gas,this wire can be used to welding the important low alloy structures, and widely used in the welding of scraper chain and hydraulic supports in mining machinery.

1. Pay attention to the gas purity and mixture ratio.
2. Keep the gas flow rate between 15 ~ 25 L / Min.
3. The extension length keep between 15 to 20mm
4. Clear the oil, rust, moisture, dust and other debris of the welded parts.
5. Keep the welding hood clean and unobstructed.
