Fundamental sources of failures: Improper Manufacturing I — Lesson 2

This lesson covers the subject of failure analysis and prevention, focusing on failures caused by deficient design and improper manufacturing procedures. It discusses the importance of following correct manufacturing procedures to avoid product failure. The lesson also explains how different manufacturing processes like casting, welding, machining, and forming can affect the mechanical properties of a product. For instance, it highlights how casting can lead to low strength and ductility, while machining can lead to residual compressive stresses, improving tensile strength and fatigue resistance.
