AWS Specification for welding consumables designations for manual electrodes (AWS A5.1 and A5.5)
1.The prefix “E” designates arc-welding electrode.
2.The first two digits of four –digit numbers and the first three digits of five-digit numbers indicate minimum tensile strength.
E60XX:60,000 psi Minimum Tensile Strength
E70XX:70,000 psi Minimum Tensile Strength
E110XX:110,000 psi Minimum Tensile Strength
3.The next –to-last digit indicates position:
EXX0X, EXX1X: All positions
EXX2X: Flat position and horizontal fillets
4.The suffix (Example: EXXX-A1) indicates the approximate alloy in the weld deposit:
