Designation:E164815Standard Reference Radiographs forExamination of Aluminum Fusion Welds1This standard is issued under the fixed designation E1648;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These reference radiographs illustrate various types andseverity levels of discontinuities in aluminum fusion welds thatmay be revealed by radiographic examination.These referenceradiographs do not specify the acceptable level of thesediscontinuities,rather they provide a visual reference forcommunicating the acceptable level.NOTE1The reference radiographs consist of a set of eight plates(812by 11 in.(22 by 28 cm),covering base material up to and including 0.75in.(19 mm)in thickness.1.2 These reference radiographs are based on two nominalweld thicknesses in wrought aluminum products and areapplicable to the thickness ranges shown in Table 1.The weldswere produced using base material plates of 6061 and 5083alloys and 5356 and 4043 gas metal-arc(GMA)electrodes.These reference radiographs are intended for use in evaluatingradiographs of welds in wrought aluminum products.They arenot recommended for use with repair welds in cast materials;however,they are appropriate for use with assembly orfabrication welds.Reference radiographs for aluminum andmagnesium castings are available in Reference RadiographsE155 and E505.1.3 The adjunct contains illustrations of representativegraded and ungraded discontinuities.Table 2 lists the discon-tinuity types and severities illustrated for each thickness ofbase material.Each of the graded discontinuity types has fiveseverity levels,1 through 5,in order of increasing severity.Theungraded discontinuities are included for informational pur-poses.1.4 From time to time,there may be minor changes to theprocess for manufacturing of the reference radiograph adjunctmaterials.These changes could include changes in the films orprocessing chemicals used,changes in the dies or printing forthe cardboard mats,etc.;however,in all cases,these changesare reviewed by the Illustration Monitoring Subcommittee andall reference radiographs are reviewed against a fixed prototypeimage to ensure that there are no changes to the acceptancelevel represented by the reference radiographs.Therefore,theadjunct reference radiographs remain valid for use with thisstandard regardless of the date of production or the revisionlevel of the text standard.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E94 Guide for Radiographic ExaminationE155 Reference Radiographs for Inspection of Aluminumand Magnesium CastingsE505 Reference Radiographs for Inspection of Aluminumand Magnesium Die CastingsE1032 Test Method for Radiographic Examination of Weld-mentsE1316 Terminology for Nondestructive Examinations2.2 ASTM Adjuncts:Reference Radiographs for Aluminum Fusion Welds:Volume 1,Thicknesses Up to and Including 0.75 in.(19 mm)33.Terminology3.1 DefinitionsDefinitions of terms relating to X-ray andgamma radiology,as used in these reference radiographs,maybe found in Terminology E1316.4.Significance and Use4.1 Use of these reference radiographs requires agreementbetween the using parties as to the acceptable level of each1These reference radiographs are under the jurisdiction of ASTM CommitteeE07 on Nondestructive Testing and are the direct responsibility of SubcommitteeE07.02 on Reference Radiological Images.Current edition approved Sept.1,2015.Published September 2015.Originallyapproved in 1995.Last previous edition approved in 2011 as E1648-95(2011).DOI:10.1520/E1648-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from ASTM Headquarters.Order RRE1648.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 discontinuity type.Illustrations are provided for welds in0.125-in.(3.2-mm)thick material and 0.50-in.(12.7-mm)thickmaterial.These illustrations are intended to be representativeof base material thicknesses up to 0.75 in.(19 mm).Use ofthese reference radiographs is not intended to be restricted tothe specific energy level or the absolute thickness lim
