Step 1
Metal macroscopic examination
Answer
Metal macroscopic examination involves a visual inspection of the metal's surface. This method can identify physical manufacturing defects that might be apparent to the naked eye or through the use of low-powered magnifying glass. It is a relatively quick process that helps in quality control by giving an overview of the metal's condition.
Step 2
Metal microscopic examination
Answer
In contrast, metal microscopic examination provides a more detailed view of the metal's characteristics. This process allows for the examination of grain size, structural details, and the presence of impurities within the metal. An optical microscope is typically employed for this type of inspection, enabling the investigator to observe features that are not visible during macroscopic examination.
