V-down a. The abbreviations indicate the welding as follows F = Flat H = Horizontal H-files = Horizontal fillets V-down = Vertical with downward progression V = Vertical

(For electrodes 3/16 in (4.8mm) and under, except5/32 ub (4.0mm)

0H = Overhead and under for classifications E7014, E7015, E7016, E7018 and E7018M. b. The term "deep" refers to direct current electrode positive (de, reserve polarity). The term "deen" refers direct current electrode negative (de, straight polarity). c. Electrodes of the E6022 classification are intended to single-pass welds only. d. Electrodes with supplemental elongation, notch, toughness, absorbed moisture and diffusible hydrogen requirements may be further identified.
