supports, byshowingthatnoneoftheshopweldsonthesesupportswouldbeoverstressed inthe"as-fabricated" condition.

Sincespecifictolerances arenot,re-quiredbyANSIB31.1,orthedesignspecification, itisITTGrinnell's positionthatsupportsfabricated withshopweldsslightlybelowthesizespecified onthedesigndrawingshouldbeacceptable providednoshopweldsareoverstressed inthe"as-fabricated" condition.

Ofthese,sixty-nine (69)werefoundtohaveweldsizesdifferent fromthedesigndrawings.

III.METHODOFANALYSISWeldstresscalculations were'erformed foreachQ-Listedsupportasrequiredtoverifythatnoneoftheshopweldswereoverstressed inthe"as-fabricated" configuration.

Thesecalculations wereperformed usingthesmallestsectionfound,carriedthefulllengthoftheweld.Thisrepresents aconservative

approach, sinceveryfewoftheshopweldsquestioned wereundersize forthefulllength.Forcesontheweldsweredetermined inaccordance withITTGrinnell's StressCriteriadatedJanuary17,1978,seeAppendixD,whichwasapprovedwithcommentsbyBechtelonMarch9,1978.Theload'perlinearinchwascalculated andcomparedtothemaximumallowable loadperlinearinchasspecified intheabovelistedStressCriteria.

analyzed, andtheactualstressinthe"as-fabricated" con-ditioncomparedagainstmutuallyagreeduponallowables.

Thecalculated safetymargins(oCratio) rangedfrom1.1to188-Throughobservation, itwasseenthatallweldswerebelowallowables; therefore, noneofthesurveyedandanalyzedsupportshaveanyshopweldswhichareoverstressed.

Asaresultofthissurvey,allQ-Listedsupportweldsonassemblies fabricated byITTGrinnellandshippedtotheSusquehanna jobsitehavebeenvisuallyinspected, calcula-tionsperformed andallweldshavebeenfoundtomeetallrequirements.
