Test positions for fillet & groove welding

What is the test positions for fillet & groove welding in case of plate & pipes?
Answer: –

Test positions for Fillet welds: –

Plate positions: –

A. Flat Position 1F : – Plates so placed that the weld is deposited with its axis horizontal & its throat vertical. Refer sketch (a).
B. Horizontal Position 2F : – Plates so placed that the weld is deposited with its axis horizontal on the upper side of the horizontal surface and against the vertical surface. Refer sketch (b).
C. Vertical Position 3F : – Plates so placed that the weld is deposited with its axis vertical. Refer sketch (c).
D. Overhead Position 4F : – Plates so placed that the weld is deposited with its axis horizontal on the underside of the horizontal surface and against the vertical surface. Refer sketch (d).

Pipe positions: –

A. Flat Position 1F : – Pipe with its axis inclined at 45to horizontal and rotated during welding so that the weld metal is deposited from above and at the point of deposition the axis of weld is horizontal and the throat vertical. Refer sketch (a).
B. Horizontal Position 2F : – Pipe with its axis vertical so that the weld is deposited on the upper side of the horizontal surface and against the vertical surface. The axis of the weld will be horizontal and the pipe is not to be rotated during welding. Refer sketch (b).
C. Horizontal Position 2FR: – Pipe with its axis horizontal and the axis of the deposited weld in the vertical plane. The pipe is rotated during welding. Refer sketch (c).
D. Overhead Position 4F : – Pipe with its axis vertical so that the weld is deposited on the underside of the horizontal surface and against the vertical surface. The axis of the weld will be horizontal and the pipe is not rotated during welding. Refer sketch (d).
E. Multiple Position 5F : – Pipe with axis horizontal and the axis of the deposited weld in the vertical Plane. The pipe is not to be rotated during welding. Refer sketch (e).

Test positions for Groove welds: –

Plate positions: –
A. Flat Position 1G : – Plate in a horizontal plan with the weld metal deposited from above. Refer sketch (a).
B. Horizontal position 2G : – Plate in a vertical plane with the axis of the weld in horizontal. Refer sketch (b).
C. Vertical position 3G : – Plate in vertical plane with the axis of the weld vertical. Refer sketch (c).
D. Overhead Position 4G : – Plate in a horizontal plane with the weld metal deposited from underneath. Refer sketch (d).

Pipe Positions: –
A. Flat Position 1G : – Pipe with its axis horizontal and rolled during welding so that the weld metal is deposited from above. Refer sketch (a).
B. Horizontal Position 2G : – Pipe with its axis vertical and the axis of weld in a horizontal plane. Pipe shall be not be rotated during welding. Refer sketch (b).
C. Multiple Position 5G : – Pipe with its axis horizontal and the welding groove in vertical plane. Welding shall be done without rotating the pipe. Refer sketch (c).
D. Multiple Position 6G : – Pipe with its axis inclined at 45to horizontal. Welding shall be done without rotating the pipe. Refer sketch (d).
