Hi guys,
SFA-5.4 1998 SECTION II
TABLE 2
TYPE OF WELDING CURRENT AND POSITION OF
WELDING
AWS
Classification a Welding Current b Welding Position c
EXXX(X)-15 dcep Alld
EXXX(X)-25 dcep H, F
EXXX(X)-16 dcep or ac Alld
EXXX(X)-17 dcep or ac Alld
EXXX(X)-26 dcep or ac H, F
NOTES
a. See Section A8, Classification as to Useability, for explanation of
positions.
b. dcep Direct current electrode positive (reverse polarity).
ac Alternating current
c. The abbreviations H and F indicate welding positions (Figure 3)
as follows:
F Flat
H Horizontal
d. Electrodes 3⁄16 in. (4.8 mm) and larger are not recommended for
welding all positions.
The -15, -16 & -17 suffixes are "all positions" but as Al stated just because it is allowed does not mean the results are all acceptable.
Scrappywelds,
SFA 5.01 lists VD as a position (I thought the same as you that it was a progression)
Notes:
a. The abbreviations indicate the welding positions as follows:
F Flat
H Horizontal
H-fillets Horizontal fillets
V-down Vertical with downward progression
V Vertical - For electrodes 3⁄16 in. (4.8 mm) and under, except 5⁄32 in. (4.0 mm) and under for classifications E7014, E7015, E7016, E7018, and E7018M.
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, E7018, and E7018M.
