AWS CODIFICATION OF CARBON STEEL AND LOW-ALLOY STEEL COATED ELECTRODES
Electrode
E First digit Second digit Third digit Fourth digit
First two digits indicate
tensile strength of the
deposited weld metal
in 1000 PSI
Third digit indicates
the welding
positions for electrodes.
1 All position
2 Flat & horizontal Fourth digit (0 to 8) indicate
3 Flat & down hand
the type of flux coating.
0 Cellulose sodium, or iron oxide mineral
1 Cellulose potassium
2 Titania sodium
3 Titania potassium
4 Iron powder titania
5 Low hydrogen lime - sodium
6 Low hydrogen lime - potassium
7 Iron oxide plus iron powder
8 Low hydrogen lime plus iron powder
9 A number left over for peculiar coating.
This number is rarely used.
