The primary enemy in welding is gravity. In the 6G position, gravity attacks the weld puddle in varying ways as you move around the pipe circumference. weld position 6g
When welding a 45-degree fixed pipe, the "high side" (top) behaves differently than the "low side" (bottom). | Position | Inclination | Pipe Rotation |
