14、 national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. Intern

15、ational organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rul

16、es given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possib

17、ility that some of the elements of this part of ISO 9692 may be the subject of patentrights.

20、 part of ISO 9692 defines the parameters characterizing the joint preparation and assembly of the most oftenencountered dimensions and shapes.The recommendations given in this part of ISO 9692 have been compiled on the basis of experience and containdimensions for types of joint preparation that are

21、 generally found to provide suitable welding conditions. However,the extended field of application makes it necessary to give a range of dimensions. The dimension ranges specifiedrepresent design limits and are not tolerances for manufacturing purposes. Manufacturing limits depend, forinstance, on w

22、elding process, parent metal, welding position, quality level, etc. Due to the common character of thispart of ISO 9692, the examples given cannot be regarded as the only solution for the selection of a joint type.Specific fields of application and manufacturing requirements may be covered by select

23、ed ranges of dimensionsspecified in the relevant application standard.SANS 9692-3:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .INTERNATIONAL STANDARD ISO 9692-3:2000(E) ISO 2000 All rights reserved 1Welding and allied processes Recomme

24、ndations for jointpreparation Part 3:Metal inert gas welding and tungsten inert gas welding ofaluminium and its alloys1 ScopeThis part of ISO 9692 specifies types of joint preparation for metal inert gas welding, MIG, (131) and tungsten inertgas welding, TIG, (141) on aluminium and its alloys.It app

25、lies to fully penetrated welds.2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions ofthis part of ISO 9692. For dated references, subsequent amendments to, or revisions of, any of these publicationsdo not apply. Howe

No cleaning fluids based onmineral oil shall be used. If plasma cutting is used, consideration shall be given to the quality of cut surfaces (e.g.cracks).

31、The longitudinal edges of the root face should be de-burred and chamfered, especially for single sided butt weldswithout backing.6 Type of joint preparationThe recommended types of joint preparation and dimensions are specified in Tables 1 to 3.The choice of joint details (angle, gap, thickness of r

32、oot face) depends on the joint thickness, the position and thewelding process. The use of larger gaps (W 1,5 mm) permits smaller angles.If gaps are W 1,5 mm, backing is preferably used.For single sided welding, backing bars should be grooved.NOTE The reference numbers have been determined in accorda

33、nce with the following scheme:The first digit corresponds with the number of the table (e.g. digit 1 for Table 1 with joint preparation for butt welds, welded fromone side), the second digit or numerical group corresponds with the number in ISO 2553 (e.g. digit 2 for square butt weld asgiven in Tabl

34、e 1 of ISO 2553:1992), the third indication, expressed by a letter, covers the variants of joint preparations.EXAMPLE Joint preparation for a butt weld, welded from one side (1), finished for single-V butt weld (3) gets the number:1.3SANS 9692-3:2009This s tandard may only be used and printed by app
