36、t 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 g
37、enerally 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
38、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 sele
39、cted ranges of dimensions specified in the relevant application standard.5DIN EN ISO 9692-3:2016-11 EN ISO 9692-3:2016 (E)1 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 TI
40、G welding (142) on aluminium and its alloys.It 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 undate
41、d references, the latest edition of the referenced 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 preparati
42、ons recommended in this part of ISO 9692 are 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. Combinati
43、ons of different processes are possible: MIG 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
44、 the reference number of the welding process 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.
45、 cracks).6DIN EN ISO 9692-3:2016-11 EN ISO 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 specified in Tables 1
46、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 should be grooved.T
47、he 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 corresponds with th
48、e 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):1.37DIN EN ISO
