14、y36 ISO/TR 17671-6:2005(E) ISO 2005 All rights reserved vForeword 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 committee
15、s. 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 Inter
16、national 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 2. The main task of technical committees is to prepare International Standards. Draft International St
17、andards 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. In exceptional circumstances, when a technical committee has collected data of a different kind
18、 from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the d
19、ata it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TR 17671-6 was prepared by Techni
20、cal Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding. ISO/TR 17671 consists of the following parts, under the general title Welding Recommendations for welding of metallic materials: Part 1: General guidance for arc weld
21、ing Part 2: Arc welding of ferritic steels Part 3: Arc welding of stainless steels Part 4: Arc welding of aluminium and aluminium alloys Part 5: Welding of clad steels Part 6: Laser beam welding Part 7: Electron beam welding ISO/TR 17671-6:2005(E) vi ISO 2005 All rights reservedIntroduction ISO/TR 1
22、7671 has been issued in several parts in order that it can be extended to cover the different types of metallic material that are produced in accordance with all International Standards for weldable metallic materials. When ISO/TR 17671 is referenced for contractual purposes, the ordering authority
23、or contracting parties should state the need for compliance with the relevant parts of ISO/TR 17671 and such of the annexes as are appropriate. This part of ISO/TR 17671 gives general guidance for the satisfactory production and control of welding and associated processes and details of some of the
24、possible detrimental phenomena that can occur, with advice on methods by which they can be avoided. It is generally applicable to laser beam processing of metallic materials and also to some extent for non-metallic materials. It is appropriate regardless of the type of fabrication involved, although
25、 the relevant product standard, structural code or design specification can have additional requirements. Permissible design stresses, methods of testing and inspection levels are not included because they depend on the service conditions of fabrication. These details should be obtained from the rel
26、evant application standard or established by agreement between the contracting parties. It has been assumed in the drafting of this part of ISO/TR 17671 that the execution of its provisions is entrusted to appropriately qualified, experienced and trained personnel. Requests for official interpretati
27、ons of any aspect of this part of ISO/TR 17671 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body.

47、nt A general checklist on protection of the environment in welding and allied processes is in preparation by CEN/TC 121. It covers laser applications. Laser beam processing introduces additional hazards over and above those normally experienced in arc welding. Specialist advice should be sought, see
48、 e.g. IEC 60825-1 and ISO 11553-1. Guidance on safety aspects related to the application of industrial robots for manipulation of the focussing devices and/or the components to be welded can be found in ISO 10218. 5 Quality requirements Laser beam welding is a complex process needing detailed proces
49、s control. All processing is performed under numerical control, necessitating programming of each single operation. The application has to be controlled at a level compatible with ISO 3834-2 and ISO 3834-5. NOTE This does not entail a requirement for certification, but the process control should operate in accordance with ISO 3834-2 and ISO 3834-5. It is a condition for efficient process contr
