12、SO (the International 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 c
13、ommittee has 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 electr
14、otechnical 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 m
15、ember bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identi
16、fying any or all such patent rights. ISO 24034 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables.

18、heir chemical composition. For titanium-welding consumables, there is no unique relationship between the product form (wire electrodes, wires or rods) and the welding process used (gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding or laser welding). For this reason, wire e
19、lectrodes, wires and rods may be classified in terms of their chemical composition. In this International Standard, the symbol of the welding process is not used, because a) different joining processes are performed with the same chemical component consumable, and b) the producer is not able to dete
20、rmine the process symbol before shipping. Also, it should be noted that the mechanical properties of all-weld metal test specimens or welded joints produced by welding consumables will vary from those obtained in production joints because of differences in welding procedure and the base-metal alloy.
21、 For this reason, the mechanical properties of all-weld metal or welded joints for titanium-welding consumables are not specified in this classification. Requests for an official interpretation of technical aspects of this International Standard should be directed to the secretariat of ISO/TC 44/SC

24、 IHS -,-,- INTERNATIONAL STANDARD ISO 24034:2005(E) ISO 2005 All rights reserved 1 Welding consumables Solid wires and rods for fusion welding of titanium and titanium alloys Classification 1 Scope This International Standard specifies requirements for the classification of solid wires and rods for
25、fusion welding of titanium and titanium alloys. The classification of the solid wires and rods is based on their chemical composition. For titanium-welding consumables, the compositions of the wire electrodes for the MIG process (metal inert gas welding) are the same as for the TIG process (tungsten
26、 inert-gas arc welding), the plasma arc process, the laser beam process, and other fusion welding processes. Therefore, the use of the word “wires/rods” in this classification refers to both “wire electrodes” and “wires and rods” in this International Standard. NOTE In this International Standard, t
27、he word “titanium” is used for “titanium and titanium alloys”. The classification of titanium wires/rods is based upon the chemical composition of the wires/rods. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, o
28、nly the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、uct, dimensions, tolerances and markings ISO 14344, Welding and allied processes Flux and gas shielded electrical welding processes Procurement guidelines for consumables 3 Classification The classification is divided into two parts: a) the first part gives a symbol indicating the product to be iden
30、tified, see 4.1. b) the second part gives a symbol indicating the chemical composition of the wires/rods, see Table 1. 4 Symbols and requirements 4.1 Symbol for the product The symbol for the solid wire and rod shall be S.

32、icates the chemical composition of a solid wire or rod, determined under the conditions given in Clause 6. The first two digits indicate the alloy group. See Annex A for an explanation of the numerical symbols. 4.3 Rounding-off procedure For the purpose of determining compliance with the requirement
33、s of this International Standard, the actual test values obtained shall be subjected to the rounding-off rules of ISO 31-0:1992, Annex B, Rule A. If the measured values are obtained by equipment calibrated in units other than those of this International Standard, the measured values shall be convert
34、ed to the units of this International Standard before rounding off. If an average value is to be compared to the requirements of this International Standard, rounding off shall be done only after calculating the average. In the case where the testing standard cited in the normative references of thi
35、s International Standard contains instructions for rounding off that conflict with the instructions of this International Standard, the rounding-off requirements of the testing standard shall apply. The rounded-off results shall fulfill the requirements of the appropriate table for the classificatio
36、n under test. 5 Mechanical properties Mechanical properties of all-weld metal or welded joints are not part of this classification. 6 Chemical analysis Chemical analysis shall be performed on specimens of the product or the stock from which it is made. See also footnote c to Table 1. Any analytical
37、technique may be used but, in case of a dispute, reference shall be made to established published methods, agreed upon between the contracting parties. 7 Retest If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Speci
38、mens for the retest may be taken from the original test sample or from a new test sample. For chemical analysis, retests need be only for those specific elements that failed to meet their test requirement. If the results of one or both retests fail to meet the requirement, the material under test sh
39、all be considered as not meeting the requirements of this specification for that classification. In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the sample or test specimen(s), or in c
40、onducting the tests, the test shall be considered invalid, without considering whether the test was actually completed, or whether the test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling
41、 the number of test specimens does not apply. 8 Technical delivery conditions Technical delivery conditions shall meet the requirements in ISO 544 and ISO 14344.
