Samples: N/A
Inspected fit -up, backing, groove angle, and root openings for welding back the access plate previously removed
at the 1.5M gallon water tank. Inspection was per welding requirements outlined in RFI #9. The fit -up for the
horizontal weld at top and vertical welds at each side of the plate were found to be in accordance with RFI #9 and
AWS D-1.1 Welding Code.
Preliminary Item. The bevel for the bottom horizontal weld where the plate is double thickness (reinforcing the
access hatch) was not made deep enough. Requested further preparation of bevel to provide full depth bevel
down to the backing plate as required for a single bevel groove weld with backing pre -qualified weld in AWS D-
1.1 Welding Code.
Arranged for further inspection to review above correction.
PRELIMINARY INSPECTION
Pending review of above -noted correction.

Inspected fit -up, backing, groove angle, and root openings for welding back the access plate previously removed
at the 1.5M gallon water tank. Inspection was per welding requirements outlined in RFI #9.
Returned to site to re -inspect complete joint penetration (CJP) weld fit -up for the access plate re -installation
bottom horizontal weld where the plate is double thickness reinforced at the access hatch. The fit -up for this weld
location was found to be in accordance with RFI #9 and AWS D-1.1 Welding Code. Also, inspected work in
progress on initial root weld passes and backing plate welds.
To the best of our knowledge, the items inspected today are in conformance with approved plans and
