Plane Panel Welded Flanges

Welded flanges will not be supplied with any GSD:s. There are several reasons for this, for example, small profile dimensions, asymmetric flanges, narrow angles in endcut geometry will mean that the GSD:s often would be positioned outside the actual profile. Instead of GSD:s a special marking for flanges is implemented as shown in the figure below. This marking defines the transverse and longitudinal position of the plate edge as well as the material orientation using the contour shown in the picture below

Figure 2:11. Marking on Welded Flange.
Line "A" defines the moulded line of the attached panel. The line "B" defines the material side (direction of line "B" = into material of panel). The corner between "A" and "B" corresponds to the position of the associated GSD on the panel (see the figure below).

Figure 2:12. Connection between GSD and Flange Marking.
The length of "A" and "B" is controlled by the parameters FLA_A and FLA_B. The marking will be placed at a distance (CORNER_DIST) from the nominal flange ends.
If, for some reason, the marking extends outside the raw profile edges, then line "A" and/or "B" will be omitted from the marking geometry. If the flange marking from both ends of the flange profile overlap, then measure "A" will be shortened accordingly.
The marking on the flange profile will be on the side that is welded to the plate edge. The GSD on the plate will be on the side defined by SBH_MARKING_SIDE.
In case the flange extends outside the plate edge, the marking will be placed at a distance (CORNER_DIST) from the plate corner. Notches in the plate geometry will be taken into consideration if the keyword USE_WELD_TRACE=YES (see the figure below).
