Macroscopic and microscopic examination is used to reveal the macroscopic or microscopic features of a welded joint, usually by the examination of transverse sections.This is done by visual and/or optical examination of the prepared surface, before or after etching.
The purpose of macroscopic and microscopic examinations is to assess the structure (including grain structure, morphology and orientation, precipitates and inclusions) independently and/or in relation to various cracks and cavities. Sections can also provide a record of sample shape in the planes of the section. Table 1 gives guidance on the assessment of features which can be detected by macroscopic and microscopic examination.
Test specimens are generally oriented perpendicular to the weld axis (transverse section), including the weld deposit and heat affected zones on both sides of the weld. However, test specimens may also apply to other orientations.
The location, orientation and number of test pieces should be specified prior to testing, for example by reference to an application standard.
The test specimen shall be prepared for examination by cutting, mounting, grinding and/or polishing and/or etching as appropriate (see ISO/TR 16060). The surface to be examined shall not be adversely influenced by these processes.AS NZS 2205.5.1 pdf free download.
