Welding is a widely used process in manufacturing, construction, and heavy industry. During welding, the material is exposed to localized high temperatures that significantly affect not only the weld metal but also the surrounding regions. These include the Weld Metal, the Heat-Affected Zone (HAZ), and the Base Metal. Each of these zones undergoes different thermal cycles and consequently exhibits different microstructural transformations, mechanical properties, and residual stresses. Understanding these transformations is crucial for ensuring the integrity and performance of welded components.
