welding positions



Welding Positions 


Welding positions have special importance in the welding operation. Different welding positions are used at different job locations according to the site facilities.
It varies slightly in plate and pipe welding position, it can be classified as follows.

Plate:-

1- Flat position 1F

In this welding position, Plates so placed that the weld is deposited with its axis horizontal & its throat will be vertical.

In this welding position, 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.

In this welding position, Plates so placed that the weld is deposited with its axis vertical




4-Overhead Position 4F

In this welding position, Plates so placed that the weld is deposited with its axis horizontal on

Pipe:-

In this welding position, Pipe with its axis horizontal and rolled during welding so that the weld metal is deposited from above.

2-Horizontal Position 2G


In this welding position, Pipe with its axis vertical and the axis of weld in a horizontal plane.
Pipe shall be not be rotated during welding.

In this welding position, Pipe with its axis horizontal and the welding groove in a vertical plane.

4-Multiple Position 6G

In this welding position, Pipe with its axis inclined at 45०to horizontal. Welding shall be done
without rotating the pipe.


5- Multiple position 6GR ( Restriction )


Welding position, 6 GR is nothing else but the same test with a restriction plate on one side of the weld, around the circumference of the pipe, to restrict the angle of the electrode or filler wire in the weld groove. 6 GR  is inclined to a 45-degree angle. The purpose of this position is to make the most difficult weld position for certification tests.
