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.
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.
