No heat treatment shall be applied to the welded joint or to the test specimen unless it is specified or permitted by the relevant application standard dealing with the welded joint to be tested. Details of any heat treatment shall be recorded in the test report. If natural ageing of aluminium alloys takes place,the time between welding and testing shall be recorded.
Shearing shall not be used for thicknesses > 8 mm. If thermal cutting or other cutting methods which could affect the cut surfaces are used to extract the test specimen from the welded plate, or from the test piece, the cuts shall be made at a distance≥3 mm from the test specimen but in any case sufficient (depending on the process used) not to introduce metallurgical effects which could affect the test results.
For transverse root and face bend tests, the test specimen thickness, ts, shall be equal to the thickness of the base material adjacent to the welded joint up to a maximum thickness of 30 mm. If the test piece thickness, t, is greater than 10 mm, the test specimen thickness, ts, may be machined or otherwise mechanically finished from one side to a thickness equal to (10±0,5) mm as indicated in Figures 1 and 2. The face or root of the weld shall be in tension when the specimen is bent.
For side bend tests, the test specimen width, b, shall be equal to the thickness of the base material of the welded joint. The specimen shall have a thickness, ts, of at least (10±0,5) mm, unless otherwise specified in the relevant application standard.
When the joint thickness exceeds 40 mm, it is permissible to split the specimen in the plane of the test piece thickness as shown in Figure 10. In these cases the location of the test specimen in the welded joint thickness shall be identified.AS NZS 2205.3.1 pdf free download.
