The weld Is partially covered by the Core Guide Lugs. Flow Stabilizers welded to the head below the weld and the Core Guide Lugs restrict the UT head from scanning the entire weld. These limitations occur between each lug set. Single sided scan parameters are used near obstructions to Improve examination coverage.

Coverage obtained on this weld is 43%.

-Lower Shell to Lower Head Weld View of TWS robot in vessel lower head region showing scan limitations caused by the lncore Nozzles and Flow Stabilizers.

The weld is partially covered by the Flow Stabilizers.

Flow Stabilizers welded to the head above the weld and the lncore Nozzles restrictthe UT head from scanning the entire weld. The Core Guide Lugs also provide some interference with robot movement.

These limitations occur between each Flow Stabilizer/Core Guide Lug set. Single-sided scan parameters are used near obstructions to improve examination coverage.
