WELD POSITIONS


QW-121 Plate Positions

QW-121.1 Flat Position 1G. Plate in a horizontal plane
with the weld metal deposited from above. Refer to figure
QW-461.3, illustration (a).

QW-121.2 Horizontal Position 2G. Plate in a vertical
plane with the axis of the weld horizontal. Refer to figure
QW-461.3, illustration (b).

QW-121.3 Vertical Position 3G. Plate in a vertical
plane with the axis of the weld vertical. Refer to figure
QW-461.3, illustration (c).

QW-121.4 Overhead Position 4G. Plate in a horizontal
plane with the weld metal deposited from underneath. Refer
to figure QW-461.3, illustration (d).

QW-122 Pipe Positions

QW-122.1 Flat Position 1G. Pipe with its axis horizontal
and rolled during welding so that the weld metal is
deposited from above. Refer to figure QW-461.4,
illustration (a).

QW-122.2 Horizontal Position 2G. Pipe with its axis
vertical and the axis of the weld in a horizontal plane.
Pipe shall not be rotated during welding. Refer to figure
QW-461.4, illustration (b).

QW-122.3 Multiple Position 5G. Pipe with its axis
horizontal and with the welding groove in a vertical plane.
Welding shall be done without rotating the pipe. Refer to
figure QW-461.4, illustration (c).

QW-122.4 Multiple Position 6G. Pipe with its axis
inclined at 45 deg to horizontal. Welding shall be done
without rotating the pipe. Refer to figure QW-461.4, illustration (d)

FOR FILLET WELDS

QW-131 Plate Positions

QW-131.1 Flat Position 1F. Plates so placed that the
weld is deposited with its axis horizontal and its throat
vertical. Refer to figure QW-461.5, illustration (a).

QW-131.2 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 to figure QW-461.5, illustration (b).

QW-131.3 Vertical Position 3F. Plates so placed that
the weld is deposited with its axis vertical. Refer to figure
QW-461.5, illustration (c).

QW-131.4 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 to figure QW-461.5, illustration (d).
