Welding is a critical manufacturing process used to join two or more metal parts by applying heat and/or pressure. The quality, strength, and integrity of welded joints are vital for the safety and performance of structures, pressure vessels, pipelines, and machinery. To ensure consistent and reliable welds, the welding process must be clearly defined, controlled, and validated through standardized documentation. Two essential documents play a central role in welding quality control and certification: the Welding Procedure Specification (WPS) and the Procedure Qualification Record (PQR).

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.

A weld seam isn’t just a shiny metallic line on the surface. Beneath it lies a world of microstructures and processes that shape the fate of the material. In welding engineering, some invisible phenomena can lead to very visible problems. In this article, we will explore two often-overlooked yet critical concepts: block segregation and terrace fracture.
