AWS D1.1-72, Section 3.6.4, requires "For buildings and tubular structure undercut chall be not more than 0.01 in. deep when its direction is transverse to primary tensile stress in the part that is undercut no more than 1/32 in. for all other situations."

AWS D1.1-72, Section 2.7.1.2 (2 ) requires "The maximum fillet we'ld size permitted clong the edges of material shall be 1/16 in. less than the thickness of base metal, for metal 1/4 in or more in thickness unless the weld is designated on the drawing to be built out to obtain the full throat thickness."

AWS D1.1-72, Section 8.15.1.6, requires " Fillet welds in any single continuous weld chall be permitted to under run the nominal fillet weld size required by 1/16 in.

without correction provided that the undersize weld does not exceed 10% of the length of the weld............"

Block 17 (NONCONFORMANCE) cont.

numbers F-3043, F-3091, F-3103, F-15765, F-16781, F-17119, F-17306, F-17626, F-19753, and F-24897 and reported this data on FQCL-962 dated January 21, 1982.

In order to provide a reduction of the original request, MPQAD conducted an overinspection on 78 structural beams purchased on one order only (P.O. F-3103) to determine if nonconformances existed in the field.

Contrary to the requirements listed in block 16, 66 weld joints were nonconforming out of 146 overinspected. This represents 41 of the 78 structural beams over-inspected . W e lding defects and beam locations are listed in Attachment A.

Block 18 (RECOMMENDED PART CORRECTIVE ACTION)

Project Engineering to devise a plan to determine the acceptability of welding on beams purchased under purchase orders: F-3043, F-3091, F-15765, F-16781, F-17119, F-17306, F-17626, F-19753, and F-24897.

NOTE: It is expected that many of the beams are totally inaccessable or will at least be difficult to inspect and repair.
