We do have a approved WPS and PQR and we are doing a repair welding without change of essential variables. Did we need to qualify a new wps separately for repair welding as per AWS D1.1 ?
As per AWS D1.1 , for Welded Restoration of Base Metal with Mislocated Holes.
"One reduced section tension test (weld metal);two side bend tests (weld metal); and three CVN tests of the HAZ (coarse grained area) removed from sample welds shall be used to demonstrate that the mechanical properties of the repaired area conform to the specified requirements of the base metal" Is there any requirement like this for repair of weld joints ?
