22、1 NE:24002 (E) 4 Introduction Responsibility for identifying the extent of qualification lies with the manufacturer/supplier on the basis of his assessment of market requirements. A product that has been qualified in accordance with the primary methods e.g. in EN 14532-1 may need evaluation through

23、one or more supplementary tests for some fields of application. EN145322:2004-23541 NE:24002 (E) 5 1 Scope This document applies to welding consumables for which supplementary qualification is required. It contains the technical requirements to be fulfilled. These supplementary tests apply for weldi

24、ng consumables, where the primary qualification is available in accordance with EN 14532-1. The supplementary tests can be carried out at any time without the need to repeat the primary tests. This document describes the testing methods, the amount of testing and the requirements for supplementary q

30、 Annex A. EN145322:2004-23541 NE:24002 (E) 6 4.2 All-weld metal All-weld metal test pieces and test specimens shall be prepared in accordance with 6.1.2 of EN 145321:2004, and with test piece type 1.3 of EN 1597-1:1997 or Figure D.1 for oxyacetylene welding. Welding shall be carried out in the flat

31、position, except where the consumable is designed exclusively for other position(s). One type of test piece with one consumable size and batch may be selected by the manufacturer, in accordance with the consumables used for primary qualification testing to EN 14532-1. 4.2.1 Post weld heat treatment

32、4.2.1.1 General Post weld heat treatment of the all-weld metal - if required by the manufacturer for the particular range of application - shall be applied to the test assembly. If the entire test assembly is too large for the furnace, it may be divided into suitable parts but not into individual te

33、st specimens. Post weld heat treatment conditions shall be stated in the report. 4.2.1.2 Stress relief For welding consumables for non-alloy, fine grain high strength and creep resisting steels the holding time shall be at least 3 h at the highest stress relief temperature (+0/-20) C for the parent

34、material groups (see Annex B) given in the required range of application for the qualification. When qualification is applied for wall thickness over 75 mm the holding time shall be at least 3 h + 1 h/25 mm wall thickness exceeding 75 mm. NOTE 1 Users may consider longer times to allow for the possi

35、bility of repair and multiple heat treatment. The test assembly shall be cooled in the furnace to a temperature 300 C or lower. Subsequent cooling may be carried out in still air. For stress relief or tempering, heating/cooling rates above 300 C shall not exceed 100 C/h. NOTE 2 Welding consumables f

36、or austenitic and austenitic-ferritic stainless steels and austenitic welding consumables used for dissimilar welds and overlays are not normally subject to stress relief. 4.2.1.3 Normalising When qualification is specifically required for a weld metal that will be normalised, the holding time shall

37、 be h at the highest normalising temperature (+0/-30) C for the parent material groups (see Annex B) mentioned in the required range of application for the qualification. The test assembly shall be cooled within 3 h to a temperature of 300 C (+0/-20)C. Subsequent cooling may be carried out in still

38、air. If tempering is to be applied, it shall be as described in 4.2.1.5. 4.2.1.4 Quenching When qualification is specifically required for a weld metal that will be quenched and tempered, quenching of the test assembly shall be carried out as required for the parent material groups (see Annex B) men

39、tioned in the required range of qualification. 4.2.1.5 Tempering When tempering is applied after either normalising or quenching, the holding time shall be 1 h/25 mm wall thickness at the highest tempering temperature (+0/-20) C for the parent material groups (see Annex B) mentioned in the required

40、range of application for the qualification. The test assembly shall be cooled in the furnace to a temperature of 300 C or lower. Subsequent cooling may be carried out in still air. EN145322:2004-23541 NE:24002 (E) 7 4.2.1.6 Solution heat treatment The holding time shall be h at the lowest solution h

41、eat treatment temperature (+30/-0) C for the parent metal groups (see Annex B) mentioned in the required range of qualification. Higher temperatures may be used if required by the welding consumable but shall be within the temperature range recommended for the parent metal. In this case the lowest t

42、emperature qualified shall be that used for the test. The test assembly shall be cooled in still air or otherwise if required. 4.2.2 Tensile tests 4.2.2.1 General Where appropriate, consumables shall be qualified for high temperature application either by high temperature tensile testing in accordan

43、ce with 4.2.2.3 for maximum application temperatures within the ranges defined in Table 1, or by creep rupture testing in accordance with 4.2.3 for higher application temperatures. 4.2.2.2 Tensile tests at room temperature Two tensile tests at room temperature (23 5) C shall be carried out for each

44、heat treatment condition. This can be reduced to one test if the manufacturer can document results of at least two previous tests. 4.2.2.3 Tensile tests at elevated temperature Two tensile tests shall be carried out at the maximum application temperature, within the range defined in Table 1, for whi

45、ch qualification is required.

46、to 48 400 C to 550 C aExplanation of the material groups see Annex G.4.2.2.4 Conditions for test specimens and testing The all-weld metal tensile test specimens of ferritic welding consumables may be exposed to a temperature not exceeding 250 C for a period not exceeding 16 h for hydrogen removal pr

47、ior to testing, alternatively a temperature not exceeding 105 C for a time not to exceed 48 h may be used. Tensile test specimens shall be of 10 mm diameter in accordance with EN 876. For all-weld metal, the test should be carried out in accordance with EN 10002-1 or EN 10002-5 and the tensile stren

For all groups of welding consumables, tested at all temperatures, the 0,2 % proof strength shall be determined, except in the case of consumables for non alloy and fine grain steels tested at room temperature (23 5) C when the lower yield strength shall be determined. The requirements at room temperature and at
