Failure Analysis of Welds

This course covers the extensive process of failure analysis and prevention, focusing on various aspects such as the steps involved in failure analysis, the method of reporting, analysis of welded joints, and the comprehensive process of failure analysis in weld joints. It also delves into the failure analysis of metallic components, including the description of the failed component, service conditions at the time of failure, manufacturing process conditions, and mechanical properties of the material. The course further explores the role of chemical composition, mechanical properties, and microstructural aspects in failure analysis. It concludes with the integration of all collected data for a well-informed conclusion about the potential causes of failure. For instance, the course uses real-world examples such as railway accidents due to rail fractures to illustrate the importance of preliminary examination, non-destructive testing (NDT), mechanical property testing, macroscopy, microscopy, and chemical analysis.
