3.6.3 Positions of Groove Welds in Plate
Figure 3.18 shows the welding positions in the most exact manner, but in practical shop fabrication,
the welding positions can be in any of the intermediate positions. Figure 3.19 shows the sectors which
are designated as certain welding positions. The sector angles are measured clockwise from the 0°
point as shown. Within one sector, the centerline of a groove cross-section can vary from one radius
to the other, and all the groove welds are considered in the same welding position. It is an
approximation with the actual welding techniques considered in different positions.
