For validation of welding WPS and PQR is sufficient.
if the client is asking the process of validation you have to submit the trial records of WPS like proposed WPS and its records. The trial record should contain the parameters of welding and consumables process considering welder and equipment are qualified. this records may be supplied until the aimed result is obtained.
For Ex:
Trial No parameters consumables result remark
1 xxxxxxxx xxxxxxxxxx Not satisfactory xxxxx
2 xxxxxxxx xxxxxxxx Satisfactory xxxx
