AWS ER80S-G is a specification for a type of steel filler wire used in welding. The "ER" stands for "electrode or rod," the "80" 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.
This filler wire is typically used to weld low-alloy steels, such as those that contain molybdenum or chromium. It is often used in the construction of pressure vessels, storage tanks, and other structures that require high strength and good toughness.
AWS A5.18 ER80S-G MIG welding wire is a solid wire for gas shielded metal arc welding, i.e. TIG and MIG-MAG welding. It can also be operated over a wider welding current range than other solid CO2 welding wires. It is suitable for the welding of high-strength steels for construction welding, vehicles, bridges, etc. ER80S-G filler wire can be used in single and multi-pass techniques.

The ER80S-G electrode specification is AWS A5.28 or ASME Section IX SFA 5.28.
ER indicates an electrode for TIG or MIG welding.
The 80 here indicates the tensile strength of the wire in Ksi (80 ksi minimum).
S indicates that the wire is solid, not flux cored.
G indicates that the classification is special and no chemical or shielding gas requirements are specified. The chemical composition requested by the buyer is available for production.
