| a.
The abbreviations F, V, OH, H, and H-fillets indicate welding positions as
follows: F = Flat; H = Horizontal; H-fillets = Horizontal fillets. |
| V
= Vertical; OH = Overhead - for electrodes 3/16 in. (4.8 mm) and under,
except 5/32 in (4.0 mm) and under for classifications E7014, |
| E7015,
E7016 and E7018; V-down = Vertical down. |
| b.
DCEP means electrode positive (reverse polarity). DCEN means electrode
negative (straight polarity). |
| c.
Electrodes of classification E6022 are for single-pass welds. |
