AS 1101.3—1987 Australian Standard GRAPHICAL SYMBOLS FOR GENERAL ENGINEERING Part 3 : WELDING AND NONDESTRUCTIVE EXAMINATION This Australian standard was prepared by Committee WD/1, Welding Definitions and Symbols. It was approved on behalf of the Council of the Standards Association of Australia on 12 November 1986 and published on 6 February 1987. The following interests are represented on Committee WD/1: Australian Welding Institute Australian Welding Research Association Bureau of Steel Manufacturers of Australia Confederation of Australian Industry CSIRO, Division of Manufacturing Technology Department of Defence Electricity Supply Association of Australia Melbourne and Metropolitan Tramways Board Metal Trades Industry Association of Australia Railways of Australia Committee Royal Melbourne Institute of Technology Review of Australian Standards. To keep abreast of progress in industry, Australi an Standards are subject to periodic review and are kept up to date by the issue of amendments or new editi ons as necessary. It is important therefore that Standards users ensure that they are in possession of the latest editi on, and any amendments thereto. Full detail s of all Australi an Standards and related publications wil l be found in the Standards Australia Catalogue of Publications; this informati on is supplemented each month by the magazine ‘The Australi an Standard’, which subscribing members receive, and which gives details of new publi cati ons, new edit ions and amendments, and of withdrawn Standards. Suggesti ons for improvements to Australian Standards, addressed to the head off ice of Standards Australi a, are welcomed. Noti fi cati on of any inaccuracy or ambiguity found in an Australi an Standard should be made without delay in order that the matter may be investigated and appropriate action taken. This Standard was issued in draft form for comment as DR 85138.

It is generally based on ANSI/AWS A2.4-79, Symbols for Welding and Nondestructive Testing, and the permission of the American Welding Society Inc. to use their standard is acknowledged. The standard provides a scheme whereby complete details of welds and welded joints can be delineated on drawings. A separate section has been included establishing symbols for use on drawings to specify requirements for non-destructive examination for determining the soundness of materials. The method for symbolic representation of welds on engineering drawings used in this standard is consistent with the ‘third angle’ method of projection, which is the preferred method given in AS 1100, Technical Drawing, Part 101—General Principles. It should be noted, however, that the scheme is equally appropriate to drawings in which the ‘first angle’ method of projection is used. The committee noted the practice currently adopted in ISO 2553, Welds—Symbolic Representation on Drawings, in regard to the position of the symbols on drawings, viz the dual reference line, and felt that this situation should not be carried over into this standard. Therefore, the practice of using one continuous reference line remains unaltered in this edition. Illustrations used with the text are intended only to show how symbols may be used to convey welding or testing information and do not necessarily represent good or accepted design practice. Copyri ght STANDARDS AUSTRALIA Users of Standards are reminded that copyri ght subsists in all Standards Australi a publications and soft ware. Except where the Copyri ght Act all ows and except where provided for below no publications or software produced by Standards Austr alia may be reproduced, stored in a retri eval system in any form or transmitt ed by any means without pri or permission in wri ti ng fr om Standards Australi a. Permission may be conditi onal on an appropriate royalt y payment. Requests for permission and information on commercial soft ware royalti es should be dir ected to the head off ice of Standards Australi a. Standards Australi a wil l permit up to 10 percent of the technical content pages of a Standard to be copied for use exclusively in-house by purchasers of the Standard without payment of a royalty or advice to Standards Austr alia. Standards Australi a wil l also permit the inclusion of its copyri ght material in computer soft ware programs for no royalt y payment provided such programs are used exclusively in-house by the creators of the programs. Care should be taken to ensure that material used is fr om the current editi on of the Standard and that it is updated whenever the Standard is amended or revised. The number and date of the Standard should therefore be clearly identif ied. The use of material in pri nt form or in computer soft ware programs to be used commercially, with or without payment, or in commercial contracts is subject to the payment of a royalty. This policy may be vari ed by Standards Austr alia at any ti me. 3. . . . . . . . . . . . . . . . . . . . . . 3. . . . . . . . . . 3. . . . . . . . . . . . . . . . . . . . . . . .
