Vertical Position (3F or 3G) In vertical position welding, the axis of the weld is approximately vertical. When welding is done on a vertical surface, the molten metal tends to run downward and pile up.Nov 25, 2021

What does 4F mean in welding?
Horizontal travel positions PD / 4F: This is the overhead position for fillet welds. The welder will be holding the torch at around 45º most of the times (even if it depends on the plate or pipe position), this time while being below the piece. PE / 4G: Overhead position for butt welds.Jun 15, 2016
What is the 3G welding position?
Welding in a 3G position means moving the torch vertically, up and down across a surface. This is in contrast with 1G (flat surface welding), 2G (horizontal welding), and 4G (overhead ceiling welding).
What type of position is called for with a 3F weld?
Welding Symbol Welding Position Weld Type
-------------- ----------------- -----------
3 F Vertical position Fillet weld
3 G Vertical position Groove weld
4 F Overhead position Fillet weld
4 G Overhead position Groove weld
What is vertical position 3F?
Vertical Position (3F or 3G) In vertical position welding, the axis of the weld is approximately vertical. When welding is done on a vertical surface, the molten metal tends to run downward and pile up.Nov 25, 2021
How do you avoid undercutting in vertical welding 3F?
E6011 electrodes can also be used for all-position welding using an alternating current (AC) welding power source. Like E6010 electrodes, E6011 electrodes produce a deep, penetrating arc that cuts through corroded or unclean metals.Dec 1, 2007
