Proper setup reduces the difficulty of the 4F position significantly.
While both are overhead, 4G refers to a groove weld (joining edges in a channel), whereas 4F is for fillet welds (joining surfaces at an angle). Key Techniques for 4F Welding Success
The primary challenge of 4F is gravity. Unlike flat or horizontal positions where gravity helps settle the puddle into the joint, in 4F, gravity pulls the puddle downward.
Understanding what goes wrong is the first step to getting it right.
Before you start welding in the 4F position, make sure you have:
Welding Metallurgy and Technique Focus: AWS 4F Position (Overhead Fillet Weld) Target Audience: Welding Students, CWI Candidates, Journeyman Welders
A successful 4F weld should meet the following criteria:
: Indicates the overhead position , where the welder works from the underside of the joint.
