The 2G tests your welder against gravity's first real challenge — the horizontal puddle that wants to sag. Pass it and you're qualified flat and horizontal. Common requirement for structural fabrication shops.
The 2G is a CJP groove weld with the plate vertical and the weld axis horizontal. Gravity pulls the puddle downward toward the bottom plate — managing that without sagging or undercut is the skill being tested.
Standard 45° groove, ¼" backing, same plate thickness options as the other positions. The challenge here is puddle control and travel speed consistency across a horizontal joint.
| Weld Type | Positions Qualified |
|---|---|
| Groove Welds (CJP & PJP) | Flat (1G), Horizontal (2G) |
| Fillet Welds | Flat (1F), Horizontal (2F) |
| Vertical/Overhead | NOT covered |
| Test Plate | Qualified Range |
|---|---|
| 3/8" | 1/8" to 3/4" |
| 1" | 1/8" to unlimited |
Horizontal welding demands constant travel speed and electrode manipulation to prevent puddle sag. Over-amperage is your enemy here — excess heat causes undercut on the top plate edge. The CWI will be looking hard at that. Keep it clean.
