Hi,

Please find below the Code interpretation. 

Question: When nozzle or branch connections are attached to the wall or head of a pressure vessel, what are the basic criteria establishing procedure and performance qualification?

Reply: For groove weld procedure qualification, the base metal thickness range for all base metals being joined in addition to the deposited weld metal thickness range for each process used must be qualified in accordance with QW-451 (see QW-202.4). Also, see exemptions in QW-202 for fillet weld procedure qualifications. 

Thanks& Regards,
