4f Welding: Position Full !exclusive!
4F
The "proper" or full name for the welding position is the Overhead Fillet Weld .
The 1G to 4F Breakdown:
- In flat welding, you drag the rod. In overhead, if you hold the rod too close, the flux touches the puddle and the rod sticks instantly because of the short circuit.
- The Tightrope: You have to hold a very tight arc length (almost touching the plate) to get good penetration, but not so tight that you short out. It requires a steady hand that many welders describe as "floating" the rod just above the surface.
Designation
: The "4" indicates the overhead position , while the "F" stands for fillet weld . Joint Type : Typically a tee joint or lap joint . 4f welding position full
Settings
: Use a lower current (amperage) than you would for flat positions to keep the puddle manageable. For a 1/8" 7018 rod, start around 110–130 amps . 2. Multi-Pass Technique (The "Solid" Build) 4F The "proper" or full name for the
