For Class D welds between nozzles with reinforcement rings and a diameter greater than 250, and the shell and head, what is the appropriate timing for non-destructive testing?
Non-destructive testing of Class D welds between nozzles with reinforcement rings and a diameter greater than 250, and the shell and head shall be carried out after welding is completed. .
What detection method should be used for testing? Radiography, ultrasonic testing, or magnetic particle/penetrant testing?
Personally, I believe that performing phased array testing between the nozzle and the shell, as well as between the nozzle and the reinforcement ring, can be done by introducing compressed air through the M10 hole, as needed for surface inspection
