Please reply with references for a senario as under,
 
a PQR has passed all mechanical tests and failed for Charpy test for base metal (weld line and HAZ charpy values are OK) then can the PQR be rejected??
 
The hardness of HAZ is almost double than weldmetal and base metal then what to do...
 


With best regards,
