8、ions, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are inclu

9、ded in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can bec

10、ome a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between

11、 the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While the AWS administers theprocess and establishes rules to promote fairness in

12、 the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whetherspecial

13、, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this standard. AWS also makes no guarantee or warranty as to the accuracy or completeness of any informationpublished herein.In issuing and making this standard available, AWS is

14、neither undertaking to render professional or other services for oron behalf of any person or entity, nor is AWS undertaking to perform any duty owed by any person or entity to someoneelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek thead

15、vice of a competent professional in determining the exercise of reasonable care in any given circumstances. It isassumed that the use of this standard and its provisions are entrusted to appropriately qualified and competent personnel.This standard may be superseded by the issuance of new editions.

16、This standard may also be corrected through publicationof amendments or errata. It may also be supplemented by publication of addenda. Information on the latest editions ofAWS standards including amendments, errata, and addenda are posted on the AWS web page (www.aws.org). Users shouldensure that th

17、ey have the latest edition, amendments, errata, and addenda.Publication of this standard does not authorize infringement of any patent or trade name. Users of this standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement

18、ofany patent or product trade name resulting from the use of this standard.The AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered,

19、 are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request,in writing, to the appropriate technical committee. Such requests should be addressed to the American Welding Society,Attention: Manag

20、ing Director, Technical Services Division, 550 N.W. LeJeune Road, Miami, FL 33126 (see Annex A).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a convenience to users of this standard, and they do n

These individualsdo not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addition, oral opinions a

It mustbe reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Commen

32、and as defined in AWS A3.0. A single passfillet weld shall be deposited on one side of the joint for approximately the full length of the test piece. Theminimum temperature of the assembly shall be 15 C 60 F. For covered electrodes, at least one electrode(and as many more as the weld permits) shall

33、be continuously consumed to within the permissible stub lengthof 50 mm 2 in. For electrodes longer than 450 mm 18 in, designed specifically for use in gravity welding, thefillet weld may be made either manually or with a device designed specifically for gravity welding. For wireelectrodes, tubular c

34、ored electrodes and wires, welding shall be continuous from start to finish of the filletweld.5.3 The fillet shall be deposited using travel speeds compatible with the consumable classification and testedto provide the fillet weld size required by the consumable classification standard.5.4 If weldin

36、oroughly removed from the jointbefore beginning welding on the second side.6 Examination of the test piece6.1 The completed fillet weld test piece shall be examined per the classification standard. Leg length shall bemeasured at a minimum of three locations along the length of the weld using an appr

37、opriate gauge todemonstrate conformity with the requirements of the consumable classification standard. For test plateswelded with covered electrodes, where two or more electrodes are used, a macrosection, approximately 25mm 1 in wide, shall be removed from a point approximately 25 mm 1 in back from

38、 the crater end of thedeposit made with the first electrode. For test plates welded with a continuous consumable or with only onecovered electrode is used, a macrosection, approximately 25 mm 1 in wide, shall be removed fromapproximately the midpoint of the weld length.6.2 One surface of the macrose

39、ction shall be polished, etched, and scribed as shown in Figure 2. Theconvexity or concavity, and leg lengths of the fillet weld shall be determined to the nearest 0.5 mm 1/64 in byactual measurement of the polished and etched macrosection.If fillet welds are required by the consumable classificatio

40、n standard on both sides of the test piece, then bothfillet welds shall be measured on the same macrosection.6.3 For fillet weld test pieces welded from one side only, when required by the consumable classificationstandard, the remaining two joint sections shall be broken longitudinally through the

41、fillet weld by a forceexerted in the direction shown in Figure 3. If, during bending, the weld pulls out of the test plate, it shall beconsidered as a no test, and the test shall be repeated without penalty.6.4 If necessary to facilitate fracture through the throat of the fillet weld, one or more of

42、 the followingprocedures may be used:a) reinforcing welds, as shown in Figure 3 a), may be added to each leg of the weld;b) the position of the web on the flange may be changed as shown in Figure 3 b);c) the face of the weld may be notched as shown in Figure 3 c);d) the test piece may be cooled down
