What should be done if RT inspection reveals whitening of the ring welds inside the pressure vessel cylinder?

During the review phase of the manufacturing process, the feasibility of non-destructive testing should be considered; it is necessary to determine whether this can be achieved through the assembly sequence. If it is not possible, coordination with the design team should be sought to eliminate non-destructive testing and replace it with a TIG welding backing process.
PT can be used, as well as ultrasound testing
