7、lassifications, 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

8、 are included 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 th

9、ey can become 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 agreeme

10、nt between 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 AWS administers the processand establishes rules to promote fairn

11、ess in the development of consensus, it does not independently test, evaluate, orverify 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, whetherspe

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

13、s not undertaking to render professional or other services for or onbehalf 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 theadvi

14、ce of a competent professional in determining the exercise of reasonable care in any given circumstances.This standard may be superseded by the issuance of new editions. Users should ensure that they have the latest edition.Publication of this standard does not authorize infringement of any patent o

15、r 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 ofany patent or product trade name resulting from the use of this standard.Finally, AWS does not monitor, police, or enforce compliance

16、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, are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may onl

17、y be obtained by sending a request,in writing, to the Managing Director, Technical Services Division, American Welding Society, 550 N.W. LeJeune Road,Miami, FL 33126 (see Annex B). With regard to technical inquiries made concerning AWS standards, oral opinionson AWS standards may be rendered. Howeve

18、r, such opinions represent only the personal opinions of the particularindividuals giving them. These individuals do not speak on behalf of AWS, nor do these oral opinions constitute officialor unofficial opinions or interpretations of AWS. In addition, oral opinions are informal and should not be u

19、sed as asubstitute for an official interpretation.This standard is subject to revision at any time by the AWS A5 Committee on Filler Metals and Allied Materials. It mustbe reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommenda-tions, additions,

20、 or deletions) and any pertinent data that may be of use in improving this standard are requiredand should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5Committee on Filler Metals and Allied Materials and the author of the comments will be informed o

21、f the Committeesresponse to the comments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals andAllied Materials to express their comments verbally. Procedures for appeal of an adverse decision concerning all suchcomments are provided in the Rules of Operation of the

22、Technical Activities Committee. A copy of these Rules can beobtained from the American Welding Society, 550 N.W.

The control of chemical composition isgenerally sufficient to ensure usability of these classifi-cations. However, a fusib

25、ility test may be specified. Fig-ure A.3 illustrates a typical Fusibility test joint in plate.This test is applied with tungsten arc torch on the faceside of a flat plate whose back is enclosed so as to retainthe purging gas at atmospheric pressure. By testing in thevertical up position for half the

26、 joint and in the flat posi-tion for the second half, the test evaluates the suitabilityof the insert to perform suitably in a pipe welded in the5G (horizontal fixed) position. A visual examination ofthe weld on both the front and back sides gives assurancethat the insert will become completely fuse

27、d and providesuitable weld contour in accordance with Note 5 ofFigure A.3.A9.2 Applications. A complete description of how touse consumable inserts is beyond the scope of this docu-ment.

Some safety and health informationcan be found in Clause A5. Safety and health infor-mation is available from other sources, including, butnot limite

30、d to Safety and Health Fact Sheets listedin A10.3, ANSI Z49.1, Safety in Welding, Cutting,and Allied Processes, and applicable federal and stateregulations.A10.2 Safety and Health Fact Sheets. The Safetyand Health Fact Sheets listed below are published bythe American Welding Society (AWS). They mayb

Base plate shall be of composition similar to the insert.2. One-half of joint shall be welded in flat posit

32、ion; the remainder, in the vertical position. All welding shall be done on the groove side.3. Argon gas (AWS A5.32/A5.32M Class SG-A) shall be used for purging and shielding electrode and back side of weld.4. Standard techniques and procedures for fusing the insert shall be followed at all times.5.

33、Upon completion of fusion, the joint shall be visually examined for compliance with the following:a. The contour of the back side surface of fused insert.(1) Reinforcement shall not exceed 3/32 in 2.4 mm.(2) Concavity shall not exceed 1/32 in 0.8 mm.(3) The contour shall have a uniform radius and sh

34、all blend smoothly into the base metal.b. The fused weld pass shall also be free of linear indications as revealed by liquid penetrant inspection on both weld surfaces withnon-water washable penetrant.Figure A.3Fusibility Test Joint5 in 127 mm3 in 76 mmINSERTCLASS 140CLASS 20+51 in 25.4 mm1/2 in 12.7 mm1-1/2 in38 mm800+51/4 in 6.4 mmDIMENSION DEPENDS ON THESIZE AND CLASS OF INSERTINSERT ALL DIMENSIONS, EXCLUDING ANGLES, ARE IN INCHES MILLIMETERS
