The work of preparing International Standard
8、s is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take
9、part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by t
10、he technical committees are circulated to the member 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 part of ISO 15792 may be the subject of pat
11、ent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15792-1 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables. ISO 15792 consists of the following parts, under the ge
12、neral title Welding consumables Test methods: ?Part 1: Test methods for all-weld metal test specimens in steel, nickel and nickel alloys ?Part 2: Preparation of single-run and two-run technique test specimens in steel ?Part 3: Classification testing of positional capacity and root penetration of wel

14、in welding procedure such as electrode diameter, width of weave, welding position and material composition. Test conditions prescribed and results required should not be considered to be requirements or expectations for a procedure qualification. -,-,- INTERNATIONAL STANDARDISO 15792-1:2000(E) ISO 2

Test pieces shall be prepared as described below. 4Test
21、plate material The material to be used for the test piece shall be compatible with the weld metal provided by the welding consumable tested. Alternatively, the groove edges and the backing strip shall be built up with at least two layers using the welding consumable being tested. -,-,- ISO 15792-1:2
22、000(E) 2 ISO 2000 All rights reserved 5Preparation of test piece The test piece shall be prepared in the form of a single V-groove on a backing strip. The backing strip shall be tack welded to the test piece on the reverse side. See Figure 1 and Table 1. The plates of the test piece shall be pre-set
23、 or restrained in such a way that a sufficiently flat test piece is produced for extraction of specimens. The welded test piece shall not be straightened. The type of test piece defines the dimensions, see Table 1. The type selected for classification purpose is specified in the relevant consumable

The welding shall be started after applying any preheating requireme
26、nts given in the consumable standard. The interpass temperature shall also be in accordance with the consumable standard. The preheat and interpass temperatures shall be measured using temperature indicator crayons, surface thermometers or thermocouples, see ISO 13916. The welding conditions used, s
27、uch as current, voltage, travel speed, weld run sequence, weld bead size, shall be in accordance with the limits specified in the relevant consumable standard. 7Heat treatment All heat treatments required for the weld metal, except hydrogen removal treatment, shall be carried out on the test piece,
28、or on sections thereof with a machining allowance. The heat treatments are specified in standards relating to welding consumables. Hydrogen removal treatment may be carried out on the test piece for tensile testing before or after final machining. The test piece may be held at a temperature not exce
29、eding 250 C for up to 16 h. 8Position of test specimens and test specimen dimensions Figures 2 and 3 respectively show the position of the tensile test specimen and of the notched impact specimens. The test pieces shall be divided by cutting (machining) or by thermal cutting. In the case of thermal
30、cutting, machining allowances of 10 mm at least on either side shall be provided for the subsequent machining of the specimens.
