29、SO 9606-2:2004 (E) 5 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 skill in accordance with this document depends on welding techniques a

30、nd 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 for all joints which are considered to weld easier on the presumptio

31、n 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 requirements, e.g. test piece dimensions, are satisfied (see EN ISO 156

32、14-2). 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. Requests for official interpretations of any aspect of this standa

33、rd 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. EN ISO 9606-2:2004 (E) 6 1 Scope This document specifies the requirements for qualification of welders for fusion welding of aluminium and aluminium all

34、oys. 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 is placed on the welders ability to manually manipulate the welding torch and thereby produc

35、e 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 mechanized and automated welding processes (see EN 1418 or ISO 14732). 2 Normative referenc
