What Causes Residual Stress In Welded Metal Components? Have you ever wondered what causes residual stresses in welded metal components and how they can impact the durability of a structure? In this detailed video, we'll explore the main factors that lead to the development of these internal stresses during welding. We’ll explain how rapid heating and cooling create temperature differences within the metal, resulting in internal tension and compression. You'll learn about the effects of thermal expansion, phase transformations, and mechanical restraints on residual stress formation. Additionally, we’ll discuss how these stresses can influence the strength and longevity of welded parts, potentially leading to cracks or failure if not properly managed.

The video also covers practical methods to reduce and control residual stresses, including heat management techniques, post-weld heat treatments, and mechanical methods like shot peening. Whether you're an engineer, fabricator, or student, understanding how residual stresses form and how to mitigate them is essential for improving weld quality and component lifespan. Join us to gain a clearer picture of what causes residual stresses in welding and discover effective strategies to keep these stresses in check for safer, more reliable metal structures.
