18、2016ISO 9692-3:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a

19、subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission

20、 (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should

21、be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

27、O 2016 All rights reservedBS EN ISO 9692-3:2016ISO 9692-3:2016(E)IntroductionThis part of ISO 9692 defines the parameters characterizing the joint preparation and assembly of the most often encountered dimensions and shapes.The recommendations given in this part of ISO 9692 have been compiled on the

28、 basis of experience and contain dimensions for types of joint preparation that are 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 specified represent design limits and are not

29、tolerances for manufacturing purposes. Manufacturing limits depend, for instance, on welding process, parent metal, welding position, quality level, etc. Due to the common character of this part of ISO 9692, the examples given cannot be regarded as the only solution for the selection of a joint type

30、.Specific fields of application and manufacturing requirements may be covered by selected ranges of dimensions specified in the relevant application standard.

31、 inert gas welding and tungsten inert gas welding of aluminium and its alloys1 ScopeThis part of ISO 9692 specifies recommended types of joint preparation for metal inert gas welding, MIG (131), and tungsten inert gas welding, TIG (141), and autogenous TIG welding (142) on aluminium and its alloys.I

32、t applies to fully penetrated welds.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the refer

33、enced document (including any amendments) applies.ISO 2553:2013, Welding and allied processes Symbolic representation on drawings Welded jointsISO 4063, Welding and allied processes Nomenclature of processes and reference numbers3 MaterialsJoint preparations recommended in this part of ISO 9692 are

34、suitable for all types of aluminium and its weldable alloys.4 Welding processesJoint preparations recommended in this part of ISO 9692 are suitable for welding carried out in accordance with the following processes as specified in Tables 1 to 3. Combinations of different processes are possible: MIG

35、welding with solid wire electrode (131); TIG welding with solid filler material (wire/rod) (TIG) (141); autogenous TIG welding (142) only applicable for butt weld between plates with raised edges (see Table 1, 1.20)NOTE The numbers in parentheses refer to the reference number of the welding process

36、specified in ISO 4063.5 FinishEdges should be prepared by mechanical means (e.g. shearing, sawing or milling). No mineral oil-based cleaning fluids shall be used. If plasma cutting is used, consideration shall be given to the quality of cut surfaces (e.g. cracks).INTERNATIONAL STANDARD ISO 9692-3:20

37、16(E) ISO 2016 All rights reserved 1BS EN ISO 9692-3:2016ISO 9692-3:2016(E)The longitudinal edges of the root face should be de-burred and chamfered, especially for single-sided butt welds without backing.6 Type of joint preparationThe recommended types of joint preparation and dimensions are specif

38、ied in Tables 1 to 3.The choice of joint details (angle, gap, thickness of root face) depends on the joint thickness, the position and the welding process. The use of larger gaps (1,5 mm) permits smaller angles.If gaps are 1,5 mm, backing is preferably used.For single-sided welding, backing bars sho

39、uld be grooved.The reference numbers in Tables 1 to 3 have been determined in accordance 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 from one side); the second digit or numerical group cor

40、responds with the number in ISO 2553 (e.g. digit 2 for square butt weld as given in ISO 2553:2013, Table 1); 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)
