Macrostructure testing to examine defects in the weld cross-section! Microstructure testing to observe fine structures.
Metallic microstructure testing, such as "macro and micro organizational observation," includes macrostructure testing using the naked eye or low magnification magnifiers (up to about 20 times) and microstructure testing that observes fine structures not discernible to the naked eye (up to about 1000 times). Macrostructure testing examines relatively broad areas for homogeneity or defects, while microstructure testing is a method that investigates a narrow range in detail at high magnification. 【Examples of Application (Excerpt)】 ■ Determining the suitability of welding construction by measuring leg length and observing the fusion state of welds ■ Observing inclusions and segregation in metallic materials ■ Investigating the presence of notches or defects in the cross-section of mechanical structures or damaged areas ■ Investigating erosion depth and corrosion patterns by observing the cross-section of corroded areas ■ Observing plating thickness, carburizing layer, and decarburization layer depth *For more details, please refer to the catalog or feel free to contact us.
