Typical example of a single sided access examination of an austenitic piping weld, examination credit can not be taken beyond the weld centerline when the beam is directed through the weld material.Although examinations are required to be performed with the ultrasonic beam directed through the weld material, however they can not be considered totally effective or creditable. Note: Typically a one-sidedausteniticweld examination with no circumferential restrictions would be indicated as 75%examination coverage or 50%if circumferential scans were limited to one side./..3 1/*I , I G I I: I I: I*/)4 w IJ#-!2C e F*I 5-tJ&t<J=-/.:-.:</.5 Item Description Value REQUIRED EXAMINATION VOLUME 1 Required examination volume in sq in.(width x height)for single scan stroke.;;liP 2 Number of scan directions (normally 4;Le.upst,dnst, cw,&ccw))4 3 Total scan volume in sq inches (Item1*Item 2)/.tJ4 4 Total length of weld/4.S 5 Total required examination volume in cubic inches (Item3*Item 4)15.08 OBTAINED EXAMINATION VOLUME 6 Examination volume achieved (sq in for single scan stroke)in 1 axial scanning fi direction (Le.upst)multiplied by the length of weld examined 7 Examination volume achieved (sq in for single scan stroke)in 1 axial scanning 3.77 direction (Le.dnst)multiplied by the length of weld examined 8 Examination volume achieved (sq in for single scan stroke)in 1 circumferential ,.885 scanning direction (Le.cw)multiplied by the length of weld examined 9 Examination volume achieved (sq in for single scan stroke)in 1 circumferential /.gg5 scanning direction (Le.ccw)multiplied by the length of weld examined 10 Determine the achieved examination volume by adding Items 6, 7, 8.and 9 7.S-4 11 Examination volume percentage [(Item 10/item 5)X 100](.5D):'SDfj9**}}
