17、ober 1999. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

STD - BSI BS EN IS0 SbOb-3-ENGL 1971 II. lbZ4bb7 07777Lib Page 4 EN IS0 9606-3: 1999 3b8 = Introduction This standard covers the principles to be observed in the approval testing of welder performance for the fusion welding of c
20、opper and copper alloys. The term “copper“ stands for copper and weldable copper alloys. The ability of the welder to follow verbal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product. Testing of skill to this standard depends on weldi
21、ng methods in which uniform rules and test conditions are complied with, and standard test pieces are used. The test weld can be used to approve a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions, are satisfied (see relevant part of EN 288-2). 1
22、Scope This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing of welder performance for the welding of copper. This standard applies to the approval testing of welders for the fusion welding of copper. Th
23、is standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to welders competence in the various fields of application. Tests will be carried out in accordance with this standard unless more severe tests are specified by the relevant application
24、standard when these are applied. During the approval test the welder should be required to show adequate practical experience and job knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be approved; information on these aspects is given in An
25、nex A. This standard is applicable when the welders approval testing is required by the purchaser, by inspection authorities or by other organizations. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized weldin
26、g. It does not cover fully mechanized and automatic processes (see 5.2). This standard covers approval testing of welders for work on semi-finished and finished products made from wrought, forged or cast material types listed in 5.4. The certificate of approval testing is issued under the sole respo
27、nsibility of the examiner or examining body. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated r

38、ility of the welder in these areas. Each criterion is considered to be a significant factor in the approval testing. The welders approval test shall be carried out on test pieces and is independent of the type of construction. 5.2 Welding processes Welding processes are defined in IS0 857 and refere
39、nce numbers of welding processes for symbolic representation are listed in EN 24063. This standard covers the following welding processes: 11 1 metal-arc welding with covered electrodes; 131 metal-arc inert gas welding (MIG welding); 141 tungsten inert gas arc welding (TIG welding); 15 plasma arc we
40、lding; 31 1 oxy-acetylene welding; other fusion welding processes by agreement. 5.3 Joint types (butt and fillet welds) Test pieces shall be produced for butt weld (BW) and fillet weld (RN) in plates (P) or pipes) (T) for approval tests in accordance with 7.2. 5.4 Material groups 5.4.1 General In or
41、der to minimize unnecessary multiplication of technically identical tests, copper with similar metallurgical and welding characteristics are grouped for the purpose of a welders approval (see 5.4.2). In general, a welders approval test shall involve depositing weld metal having a chemical compositio
42、n compatible with any copper in the parent metal group(s). The welding of any one material in a group confers approval on the welder for the welding of all other materials within the same group. When welding parent metals from two different groups which do not give approval to each other according t
43、o table 4 (see 6.4), an approval for the combination as a separate group is required. When the filler metal is dissimilar to the parent metal group, an approval for that combination of parent metal groiir, and filler metal is needed, except when permitted by table 4. 5.4.2 Copper groups of parent me
44、tal 5.4.2.1 General Copper casting alloys are included in the following groups but the filler metal shall be compatible with the filler metal used for the wrought materials in the same group.

47、 EN 288-2). t 5.6 Dimensions The approval test should be based on the thickness of the material (.e. plate thickness or wall thickness of pipe) and pipe diameters which the welder will use in production. A test is listed for each of the ranges of plate thickness and pipe wall thickness or pipe diame
