The problem with sloppy work is that the supply FAR EXCEEDS the demand
RE: notch toughness test
Thus a new PQR is needed.
If you stick the same PQR regime: same base metal( preferably with same CE), welding consumables, welding parameters, PWHT cycle, only an impact test could be used an addendum to the existing PQR..
Thanks.
