For profiles that are less than 900 millimeters long, one tack is welded every UoM millimeters. The first work phase at the GMP is setting up the cassettes UoM minute(s) per cassette. After that, T-bars are selected from the cassette with the portal UoM minute(s) per T-bar and aligned UoM minute(s) per T-bar. After the T-bars are selected and aligned, the welding can begin.

The count of the tacks being welded is determined as the count of the intersections between T-bars and stiffeners multiplied by the Tacks per Intersection value plus tack welds per each T-bar. By default, the tack weld value, which is defined in System Settings > Operational Settings > Panels-Work Time Calculations under Tacks per Intersection, is set to 2. You can change this value.

By default, there are three tack welds at the intersection of a T-bar and a stiffener. You can modify this setting in System Settings. T-bars that do not intersect with stiffeners are tack welded independently. For these kinds of T-bars, one tack weld is welded every UoM millimeter(s). The time it takes to weld one tack is calculated in UoM minute(s) per tack weld. The tack setup time is measured in UoM minute(s) per tack. The last phase is to remove the cassettes UoM minute(s) per cassette. The number of tacks per intersection is also configurable, but by default there are two tack welds in every intersection.
