Weld Global

A global weld assessment, called Weld Global, is available for shell and solid elements. The weld geometry is not considered in detail, but the actual notch cases and FAT classes for welds can be used. Stresses are taken directly from the top and bottom side of shells or from the surface of solid elements. In this mode LIMIT searches for the most disadvantageous orientation of the weld (cutting plane method) and will list the corresponding degrees of utilization.

The method can give a quick overview of higher stressed regions in the structure, but it is not conservative in case of partial penetration or one-sided fillet welds. In many cases with full penetration welds this procedure is conservative. The best way to assess welded structures, however, is to use the assessment type Weld.
