There are different positions for plate, fillet and tube. They are as follows. ANSI/AWS B2.1:1998 Specification for Welding Procedure and Performance Qualification has a more detailed explanation than I am able to offer.
Test Plate Positions (Groove Weld)
1G - Plates horizontal
2G - Plates vertical, weld axis horizontal
3G - Plates vertical, weld axis vertical
4G - Plates horizontal overhead

Test Plate Positions (Fillet Weld)
1F - Flat position, Weld throat vertical
2F - Horizontal position, one plate must be horizontal
3F - Vertical position
4F - Overhead position, one plate must be horizontal

Test Pipe or Tube Positions (Groove Weld)
1G - Pipe horizontal & rotating, weld flat on near top
2G - Pipe vertical & stationary, weld horizontal
5G - Pipe horizontal fixed, weld flat, vertical, overhead
6G - Pipe inclined at 45 degrees, fixed
