BS EN 287-1:2011EN 287-1:2011 (E) 5 Introduction The ability of a welder to follow verbal or written instructions and verification of a persons
25、 skills is an important factors in ensuring the quality of the welded product. The testing of a welders skill in accordance with this standard depends on welding techniques and conditions used in which uniform rules are complied with and standard test pieces are used. The principle of this standard
26、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 easier to weld on the presumption that the welder has received a specific training and/or has industrial practice within the range of qualification. The qualif
27、ication test can be used to qualify a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions and testing requirements are satisfied (see EN ISO 15614-1). At the end of its period of validity, the existing and valid qualification testing of welders in a
28、ccordance with the requirement of the previous edition of this standard may be revalidated according to the previous edition. Alternatively, the range of qualification may be updated in accordance with this edition. All new qualifications and re-qualifications shall be in accordance with this editio
29、n. BS EN 287-1:2011EN 287-1:2011 (E) 6 1 Scope This European Standard defines the qualification testing of welders for the fusion welding of steels. It provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted indepe
30、ndently of the type of product, location and examiner/examining body. When qualifying welders, the emphasis is placed on the welders ability to manually manipulate the electrode / welding torch / welding blowpipe and thereby producing a weld of acceptable quality. The welding processes referred to i
31、n this standard include those fusion-welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418). 2 Normative references The following referenced documents are indispensable for the application of thi
