Martin Willinger, who is based in Austria, shared this weld image with us. Weld specimens can involve wide variations in material hardness across the specimen, either because of phase changes during welding or because the joint incorporates dissimilar metals. The weld metal may contain hard precipitates or some indigenous weld defect. Therefore, it is important that the preparation method ensures that polish relief between microstructural features is minimal and all microstructural elements are retained. In this respect, semiautomatic or automatic preparation equipment is preferred, as it provides consistency and reproducibility of polish, which facilitates accurate microstructural analysis.
