Stiffener Mounting (SMP) and Stiffener Welding (SWP) are combined as one work phase: SMWP. Depending on the required configuration, they can be separated into two work phases.

In the Stiffener Mounting phase, profiles need to be installed manually in Service Portal (SP) if the length of the profiles is less than 900mm. Also, non-longitudinal stiffeners are installed manually. The stiffener mounting begins with loading a new cassette and selecting the first profile, UoM minute(s) per cassette. After the initial loading, the mounting process begins. This phase includes portal movement UoM minute(s) per row in the cassette.

  • Transferring the profile from PFP to Stiffener Mounting UoM minute(s) per row in the cassette

  • Aligning the profile in the cassette UoM minute(s) per profile

  • Welding a tack every UoM millimeter(s)

It takes UoM minute(s) per tack weld.

Next, the cassettes are removed UoM minute(s) per cassette, and the profiles are manually adjusted for welding. The manual adjustments before welding include:

  • Tacking the profiles at the edges of the panel UoM minute(s) per row in the cassette

  • Grinding the welding seams to fit the profile UoM minute(s) per row in the cassette

  • Adjusting the profiles to be in a 90-degree angle to the panel UoM minutes per row in the cassette

After the profiles are mounted on top of the panel, the Stiffener Welding (SWP) work phase can begin. First, the panel needs to be aligned UoM minute(s) per panel, and the portal positioned UoM minute(s) per run in panel. The number of stiffeners in a row should be divided into a set of three to get the run count. You can adjust this using the Profile Count parameter. The length of the run is determined by the length of the longest stiffener in the group.

The next phase is welding the stiffeners in place. Welding time is calculated in UoM millimeter(s) per minute. Corners can be welded manually UoM minute(s) per stiffener. After the corners are welded, they need to be ground. Grinding time is calculated in UoM minute(s) per stiffener. The last work phase is cleaning the work station UoM minute(s) per run.
