which he will date and certify. The Laboratory Test Reports will be maintained on file
by the Quality Control Manager.
6.2.3 The Fabrication Engineer is responsible for assigning the WPS for welding of new
fabrication to the ASME Code and for repair or alteration welding to the National
Board Inspection Code. The applicable WPS number shall be included on the Certified
Drawing. In the case of dispositioning of in-process nonconformities involving welded
repairs, the Quality Control Manager shall be responsible for assigning WPS's on the
