- Denotes those persons who attended the Exit Interview. (See paragraph I.)
. B. Previously Identified Items (Closed) Deviation (Report No. 78-01): Welding Procedure No. AWP-3, Revision 1, specified a weld reinforcement thickness of 1/8 inch '
which exceeded the 3/32 inch _ thickness established by the table in NB 4426.1, for materials with thickness of 3/16 ' inch to one (1) inch inclusive.
The inspector verified the procedure had been revised to require
. . . 3/32" maximum 1" to 2" inclusive nominal thickness at the weld."
(0 pen) Deviation (Report No. 78-01): WC-A Engineering Instruction Notice dated April 22, 1977, was not implemented and hardware was being machined without the 3/16 inch radius on the I. D. of the backfacing.
The inspector verified that all drawings had been revised to require a 3/16 inch minimum radius however a finite analysis had not been completed and checked. The analysis will be made available to the inspector on a subsequent inspection.
(0 pen) ' unresolved Item (Report No. 78-01): The procedure qualifica-tion record for WC-A welding procedure AWP-6, Revision 3, does not indicate the specific gas flow rate used for the different cup sizes in performing the procedure qualification, and WC-A did not have records available to resolve this matter.
