In fabrication drawing, Tube to  tubesheet joint with 4mm projection.
in the Mock-up/PQR, vendor kept 0.5mm projection, but fused the tube with the tubesheet.

Is vendor to provide mock-up with 4mm projection, or change only the WPS to show 4mm projection in the joint, with the same PQR.

as per QW 288 this is not an essential variable, hence in my opinion revision of WPS is OK.
