CONSUMABLES CLASSIFICATION TABLES
AWS A5.1-91 classifies Shielded Metal Arc Welding (SMAW / MMAW) electrodes by using a ries of letters and digits broken into two alpha numeric groups parated by a hyphen.
eg: E7018 H4R. NB. The alpha numeric group after the four digit number (or five in the ca of E7018-1) is optional. ie. H4R is optional.
The following layout outlines this classification system in part only. For full details CIGWELD recommend you refer to the current published version of AWS A5.1 obtainable from the American Welding Society,550 N.W. LeJeune Road, Miami, Florida 33126, USA.
(1)Yield on E6022 electrodes is not specified and E7018M may have a range of 53-72 ksi for all diameters other than 3/32≤(2.4mm) which is 53-77 ksi. (2)Minimum elongation for E6012, E6013, E7014 and E7024
types is 17%. Elongation on E6022 electrodes is not specified, and E7018M types are required to meet 24%.

8= the fourth digit indicates the Flux type and Welding Current / Polarity to be ud.EG: Hydrogen Controlled Low Iron Powder A.C. & D.C.+,medium penetration.See Table 2 for details.
R = the last letter indicates the coating is Moisture Resistant. Tested electrodes as received or conditioned shall exhibit not >0.3% (by Wt) of moisture after exposure to an environment of 80°F & 80 %
relative humidity for a period of not less than 9 hours.
APPLICABLE to E7016, E7018 and E7024 type electrodes only.
This number indicates that the electrode meets the requirements for improved impact toughness. In the ca of an E7024 ductility “elongation” is also improved from 17%.
