Pl. guide me if we are going to patch weld externally then what will the thickness of patch plate and what will be the welding criteria ( Maintaining some specific flow /pressure /temp ) to weld with shell. Also shell longitudinal and circumferential joints may across the welding of patch plate, is those intersection point welding is allowed or not.Pl. give some standard reference for this job.
