26、ndard covers the principles to be observed in the approval testing of welder performance for the fusion welding of copper 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

27、 important factors in ensuring the quality of the welded product. Testing of skill to this standard depends on welding 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 provid

28、ed that all the relevant requirements, e.g.test piece dimensions, are satisfied (see relevant part of EN288-2). 1 Scope This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing of welder performance for th

29、e welding of copper. This standard applies to the approval testing of welders for the fusion welding of copper. This 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 b

30、e carried out in accordance with this standard unless more severe tests are specified by the relevant application 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 proces

31、ses, materials and safety requirements for which he is to be approved; information on these aspects is given in Annex 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

32、in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automatic processes (see5.2). This standard covers approval testing of welders for work on semi-finished and finished products made from wrought

33、, forged or cast material types listed in5.4. The certificate of approval testing is issued under the sole responsibility of the examiner or examining body. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative r

34、eferences are cited at the appropriate places in the text and the publications are listed hereafter.

46、ance with7.2. 5.4 Material groups 5.4.1 General In order to minimize unnecessary multiplication of technically identical tests, copper with similar metallurgical and welding characteristics are grouped for the purpose of a welders approval (see5.4.2). In general, a welders approval test shall involv

47、e depositing weld metal having a chemical composition 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

48、which do not give approval to each other according to Table 4 (see6.4), 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 group and filler metal is needed, except when permi

49、tted by Table 4. 5.4.2 Copper groups of parent metal 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.
