ISO 9692-3:2000(E)
Foreword ISO (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 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 (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules 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 possibility that some of the elements of this part of ISO 9692 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 9692-3 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 7, Representation and terms. ISO 9692 consists of the following parts, under the general title Welding and allied processes — Recommendations for joint preparation: ¾
Part 1: Manual metal-arc welding, gas-shielded metal-arc welding and gas welding of steels
¾
Part 2: Submerged arc welding of steels
¾
Part 3: Metal inert gas welding and tungsten inert gas welding of aluminium and its alloys
¾
Part 4: Clad steels

ISO 9692-3:2000(E)
Introduction This 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 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 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. Specific fields of application and manufacturing requirements may be covered by selected ranges of dimensions specified in the relevant application standard.

ISO 9692-3:2000(E)
Welding and allied processes — Recommendations for joint preparation — Part 3: Metal inert gas welding and tungsten inert gas welding of aluminium and its alloys
1
Scope
This part of ISO 9692 specifies types of joint preparation for metal inert gas welding, MIG, (131) and tungsten inert gas welding, TIG, (141) on aluminium and its alloys. It applies to fully penetrated welds.
2
Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 9692. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 9692 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 2553:1992, Welded, brazed and soldered joints — Symbolic representation on drawings. ISO 4063:1998, Welding and allied processes — Nomenclature of processes and reference numbers.
3
Materials
Joint preparations recommended in this part of ISO 9692 are suitable for all types of aluminium and its weldable alloys.
4
Welding processes
Joint 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: ¾
metal inert gas welding (MIG) (131)
¾
tungsten inert gas welding (TIG) (141)
NOTE
The numbers in parantheses refer to the reference number of the welding process specified in ISO 4063.

5
Finish
Edges should be prepared by mechanical means (e.g. shearing, sawing or milling). No cleaning fluids based on mineral oil shall be used. If plasma cutting is used, consideration shall be given to the quality of cut surfaces (e.g. cracks). 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 preparation
The recommended types of joint preparation and dimensions are specified 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 (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 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 corresponds with the number in ISO 2553 (e.g. digit 2 for square butt weld as given in Table 1 of ISO 2553:1992), the third indication, expressed by a letter, covers the variants of joint preparations.
