It cites the base metals and operating conditions necessary to makethe weldment, the filler metal spe
5、cifications, and the allowable joint designs for fillet and groove welds. This SWPS wasdeveloped primarily for pipe applications.International Standard Book Number: 0-87171-509-0American Welding Society550 N.W.

7、anWelding 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 included in federal or state laws an
8、d regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those laws andreg
9、ulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWS stan-dard must be by agreement between the contracting parties.AWS
10、American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus.

IntroductionThe American Welding Society (AWS) Board of Directorshas adopt
39、ed a policy whereby all official interpretations ofAWS standards are handled in a formal manner. Under thispolicy, all interpretations are made by the committee that is responsible for the standard. Official communicationconcerning an interpretation is directed through the AWSstaff member who works
40、with that committee. The policyrequires that all requests for an interpretation be submittedin writing. Such requests will be handled as expeditiouslyas possible, but due to the complexity of the work and theprocedures that must be followed, some interpretationsmay require considerable time.A2. Proc
41、edureAll inquiries shall be directed to:Managing DirectorTechnical Services DivisionAmerican Welding Society550 N.W. LeJeune RoadMiami, FL 33126All inquiries shall contain the name, address, and affilia-tion of the inquirer, and they shall provide enough infor-mation for the committee to understand
42、the point ofconcern in the inquiry. When the point is not clearlydefined, the inquiry will be returned for clarification. Forefficient handling, all inquiries should be typewritten andin the format specified below.A2.1 Scope. Each inquiry shall address one singleprovision of the standard unless the
43、point of the inquiryinvolves two or more interrelated provisions. Theprovision(s) shall be identified in the scope of the inquiryalong with the edition of the standard that contains theprovision(s) the inquirer is addressing.A2.2 Purpose of the Inquiry. The purpose of the inquiryshall be stated in t
44、his portion of the inquiry. The purposecan be to obtain an interpretation of a standardsrequirement or to request the revision of a particularprovision in the standard.A2.3 Content of the Inquiry. The inquiry should beconcise, yet complete, to enable the committee tounderstand the point of the inqui
45、ry. Sketches should beused whenever appropriate, and all paragraphs, figures,and tables (or annex) that bear on the inquiry shall becited. If the point of the inquiry is to obtain a revision ofthe standard, the inquiry shall provide technicaljustification for that revision.A2.4 Proposed Reply. The i
46、nquirer should, as aproposed reply, state an interpretation of the provisionthat is the point of the inquiry or provide the wording fora proposed revision, if this is what the inquirer seeks.A3. Interpretation of Provisions ofthe StandardInterpretations of provisions of the standard are made bythe r
47、elevant AWS technical committee. The secretary ofthe committee refers all inquiries to the chair of the particular subcommittee that has jurisdiction over the por-tion of the standard addressed by the inquiry. The sub-committee reviews the inquiry and the proposed reply toStandard Welding Procedure
