| Clock position | Welding angle | Puddle behavior | Technique | |----------------|---------------|----------------|------------| | (just after bottom) | Slightly uphill | Puddle wants to drop | Push rod, keep short arc; slow, small oscillation | | 5:30 to 3 (lower quadrant) | 10–15° uphill | Gravity helps slightly | Consistent travel speed; avoid excessive weave | | 3 to 12 (upper half) | Overhead → vertical → flat top | High sag risk | Keep puddle small; watch keyhole (root pass) | | 12 o’clock (top) | Near-flat | Can overfill if too slow | Quick weave or stringer, minimal dwell at edges |
