AWS ER110S-G / ISO G69 4 M21 ZMn3NiMo Welding Wire

AWS ER110S-G is a specification for a type of steel filler wire used in welding. The “ER” stands for “electrode or rod,” the “110” 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.
