The work of prep
22、aring 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
23、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 2. The main task
24、of technical committees is to prepare International Standards. 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
25、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.

EN ISO 3834-1:2005vIntroduction Processes such as fusion welding are widely used to manufacture many products. In some companies, they are the key feature of produ
30、ction. Products may range from simple to complex. Examples include pressure vessels, domestic and agricultural equipment, cranes, bridges, transport vehicles and other items. These processes exert a profound influence on the cost of manufacture and quality of the product. It is important, therefore,
31、 to ensure that these processes are carried out in the most effective way and that appropriate control is exercised over all aspects of the operation. It is emphasised that ISO 3834 is not a quality management system standard replacing ISO 9001:2000. However, it can be a useful tool when ISO 9001:20
32、00 is applied by manufacturers. Specification of quality requirements for welding processes is important because the quality of these processes cannot be readily verified. Therefore, they are considered to be special processes as noted by ISO 9000:2000. Quality cannot be inspected into a product, it
33、 has to be built in. Even the most extensive and sophisticated non-destructive testing does not improve the quality of the product. For products to be free from serious problems in production and in service, it is necessary to provide controls, from the design phase, through material selection, into
34、 manufacture and subsequent inspection. For example, poor design may create serious and costly difficulties in the workshop, on site, or in service. Incorrect material selection may result in problems, such as cracking in welded joints. To ensure sound and effective manufacturing, management needs t
35、o understand and appreciate the sources of potential trouble and to implement appropriate procedures for their control. ISO 3834 identifies measures that are applicable for different situations. Typically, they may be applied in the following circumstances: in contractual situations: specification o
36、f welding quality requirements; by manufacturers: establishment and maintenance of welding quality requirements; by committees drafting manufacturing codes or application standards: specification of welding quality requirements; by organizations assessing welding quality performance, e.g. third part
37、ies, customers, or manufacturers. ISO 3834 can be used by internal and external organizations, including certification bodies, to assess the manufacturers ability to meet customer, regulatory or the manufacturers own requirements.

38、tallic materials Part 1: Criteria for the selection of the appropriate level of quality requirements 1 Scope This part of ISO 3834 provides a general outline of ISO 3834 and criteria to be taken into account for the selection of the appropriate level of quality requirements for fusion welding of met
39、allic materials, among the three levels specified in ISO 3834-2 3, ISO 3834-3 4and ISO 3834-4 5. It applies to manufacturing, both in workshops and at field installation sites. NOTE 1 ISO 3834-2, ISO 3834-3 and ISO 3834-4 provide complete sets of quality requirements for process control related to a
40、ll fusion welding processes (for each process separately or in combination as specified). ISO 3834-5 specifies the documents with which it is necessary to conform to claim conformity to the quality requirements of ISO 3834-2, ISO 3834-3 or ISO 3834-4. This part of ISO 3834 does not specify requireme
41、nts for a total quality management system. However, Clause 6 identifies quality management system elements where their inclusion will complement ISO 3834. NOTE 2 ISO 3834-2, ISO 3834-3 and ISO 3834-4 may be used on their own by a manufacturer or in conjunction with ISO 9001:2000. 2 Normative referen

For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 9000:2000, Quality management systems Fun
43、damentals and vocabulary 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 9000:2000 and the following apply. 3.1 design specification requirements for products specified by customers or by the organization in anticipation of customer requirements, or
44、by regulation NOTE The requirements for products and in some cases associated processes can be contained in, for example, technical specifications, product standards, process standards, contractual agreements and regulatory requirements. 3.2 qualified person person whose competence and knowledge hav
45、e been obtained by education, training and/or relevant practical experience EN ISO 3834-1:20052 NOTE In order to demonstrate the level of competence and knowledge, a qualification test may be required. 3.3 construction product, structure or any other welded item 3.4 manufacturer fabricator person or
46、 organization responsible for the welding production 3.5 sub-contractor supplier of products, services and/or activities to the manufacturer in a contractual situation 3.6 welding operator person who performs fully mechanised or automatic fusion welding processes 4 General outline of ISO 3834 ISO 38
47、34 specifies quality requirements suitable for fusion welding processes of metallic materials. The requirements contained within this International Standard may be adopted for other welding processes. These requirements relate only to those aspects of the quality of the products, which may be influe
48、nced by fusion welding, without being assigned to any specific product group. ISO 3834 therefore provides a method to demonstrate the capability of a manufacturer to produce products of the specified quality. It was prepared such that: a) it is independent of the type of construction manufactured; b
49、) it defines quality requirements for welding in workshops and/or on site; c) it provides guidance for describing a manufacturers capability to produce constructions to meet specified requirements; d) it provides a basis for assessing a manufacturers welding capability. ISO 3834 is appropriate when demonstration of a manufacturers capability to produce welded constructions, fulfilling specified quality requirements, is specified in one or more of the following: a specification; a product standard; a regulatory re
