What does the ER prefix in ER480S-2 indicate?

Explanation:
ER indicates a filler metal used to deposit weld metal. In GTAW, the prefix shows that the material is the electrode/rod that becomes part of the weld, not the base metal or a welding procedure spec. The numbers that follow relate to the specific alloy composition and strength, but the ER prefix itself identifies this as the filler alloy you would use to fill the joint.
