Metallographic Quality Control of Welding and Brazing
Metallography serves as an invaluable quality control technique in many welding and brazing operations in the energy field. It often supplements nondestructive testing processes such as dye-penetrant and radiography. Additionally, it can provide information ordinarily not obtainable by conventional inspection procedures. This paper describes a number of case histories illustrating the value of metallography in assuring integrity in the fabrication of metals and components in energy systems.
