Designation:E16413Standard Practice forContact Ultrasonic Testing of Weldments1This standard is issued under the fixed designation E164;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This practice covers techniques for the ultrasonicA-scanexamination of specific weld configurations joining wroughtferrous or aluminum alloy materials to detect weld disconti-nuities(see Note 1).The reflection method using pulsed wavesis specified.Manual techniques are described employing con-tact of the search unit through a couplant film or water column.1.2 This practice utilizes angle beams or straight beams,orboth,depending upon the specific weld configurations.Prac-tices for special geometries such as fillet welds and spot weldsare not included.The practice is intended to be used onthicknesses of 0.250 to 8 in.(6.4 to 203 mm).NOTE1This practice is based on experience with ferrous andaluminum alloys.Other metallic materials can be examined using thispractice provided reference standards can be developed that demonstratethat the particular material and weld can be successfully penetrated by anultrasonic beam.NOTE2For additional pertinent information see Practice E317,Terminology E1316,and Practice E587.1.3 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.1.4This 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:2E317 Practice for Evaluating Performance Characteristics ofUltrasonic Pulse-Echo Testing Instruments and Systemswithout the Use of Electronic Measurement InstrumentsE543 Specification for Agencies Performing NondestructiveTestingE587 Practice for Ultrasonic Angle-Beam Contact TestingE1316 Terminology for Nondestructive Examinations2.2 ASNT Document:Recommended Practice SNT-TC-1A Personnel Qualifica-tion and Certification in Nondestructive Testing32.3 ANSI/ASNT Standard:ANSI/ASNT CP-189 ASNT Standard for Qualification andCertification of Nondestructive Testing Personnel32.4 ISO Standard:ISO 2400 Reference Block for the Calibration of Equipmentfor Ultrasonic Examination42.5 AIA Standard:NAS-410 Certification and Qualification of NondestructiveTesting Personnel53.Significance and Use3.1 The techniques for ultrasonic examination of weldsdescribed in this practice are intended to provide a means ofweld examination for both internal and surface discontinuitieswithin the weld and the heat-affected zone.The practice islimited to the examination of specific weld geometries inwrought or forged material.3.2 The techniques provide a practical method of weldexamination for internal and surface discontinuities and arewell suited to the task of in-process quality control.Thepractice is especially suited to the detection of discontinuitiesthat present planar surfaces perpendicular to the sound beam.Other nondestructive examinations may be used when porosityand slag inclusions must be critically evaluated.1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.06 onUltrasonic Method.Current edition approved June 1,2013.Published June 2013.Originallyapproved in 1960.Last previous edition approved in 2008 as E164-08.DOI:10.1520/E0164-13.2For 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 TheAmerican Society for Nondestructive Testing(ASNT),P.O.Box 28518,1711 Arlingate Ln.,Columbus,OH 43228-0518.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036.5Available from Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.3 When ultrasonic examination is used as a basis ofacceptance of welds,there should be agreement between themanufacturer and the purchaser as to the specific referencestandards and limits to be used.Examples of reference stan-dards are given in Section 7.A detailed procedure for weldexaminatio
