AWS ER80S-D2 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 “D2” at the end of the specification indicates that the filler wire is designed for use in the shielded metal arc welding (SMAW) process, also known as “stick welding.”
In addition to a significant amount of silicon and manganese, this wire contains a 0.50% molybdenum alloy to produce welds with high ductility, excellent impact values, and tensile strength.
