7、ternational 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 h
8、as 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
9、 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 Standards adopted by the technical committees are circulated to the member bodi
10、es for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

25、 testing of welders - Fusion welding ISO 9606-2:2004(E) vi ISO 2004 All rights reserved Introduction The ability of a welder to follow verbal or written instructions and verification of a welders skills are important factors in ensuring the quality of the welded product. The testing of a welders ski
26、ll in accordance with this document depends on welding techniques and conditions used in which uniform rules are complied with, and standard test pieces are used. The principle of this document is that a qualification test qualifies the welder not only for the conditions used in the test, but also f
27、or all joints which are considered to weld easier on the presumption that the welder has received a particular training and/or has industrial practice within the range of qualification. The qualification test can be used to qualify a welding procedure and a welder provided that all the relevant requ
28、irements, e.g. test piece dimensions, are satisfied (see EN ISO 15614-2). Qualifications in accordance with EN 287-2 or ISO 9606-2 existing at the date of publication of this document are, at the end of their period of validity, to be interpreted in accordance with the requirements of this standard.
29、 Requests for official interpretations of any aspect of this standard should be directed to the Secretariat of ISO/TC 44/SC 11 via your national standards body, a complete listing which can be found at www.iso.org. ISO 9606-2:2004(E) ISO 2004 All rights reserved 1 1 Scope This document specifies the
30、 requirements for qualification of welders for fusion welding of aluminium and aluminium alloys. This document provides a set of technical rules for systematic qualification of welders which are independent of product type, location and examiner/examining body. When qualifying welders, the emphasis
31、is placed on the welders ability to manually manipulate the welding torch and thereby produce a weld of acceptable quality. The welding processes referred to in this document include those fusion welding processes which are designated as manual or partly mechanized welding. It does not qualify fully
32、 mechanized and automated welding processes (see EN 1418 or ISO 14732). 2 Normative references The following referenced documents are indispensable for the application of this document.

For each essential variable a range of qualificati

If the welder has to weld outside the range of qualification a new qualification test is required. The essential variables are: a) welding processes; b) product type (plate and pipe);
49、c) type of weld (butt and fillet); d) material groups; 2) The word “plate“ alone or in combination is used to mean “wrought plate“ and “flat extruded bars“. 3) The word “pipe“ alone or in combination, is used to mean “pipe“, “tube“ or “hollow section“.
