Note: AWS A5.1 covers carbon steel electrodes. AWS A5.5 covers low-alloy steel electrodes with suffix (e.g., E8018-C3 where -C3 indicates 1% nickel).

Reference

AWS A5.1 SMAW Electrode Classification System: E = Electrode First 2-3 digits = Min tensile strength (ksi) Second-to-last digit = Position (1=all, 2=flat/horiz, 4=flat/horiz/OH/vert-down) Last digit = Coating type and current polarity Example: E7018 = 70 ksi, all positions, low-H iron powder, AC/DCEP
