Microstructural and Mechanical Changes in the Weld Metal, Heat-Affected Zone (HAZ), and Fusion Boundary

Aygün Karaköse
in Theory
2 0 Intermediate
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.

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).

0 0 Intermediate
Welding is an indispensable joining method in modern manufacturing and construction. The quality of a welded joint is influenced not only by the welder’s skill but also by the proper selection of the welding process, welding position, and most critically, the weld joint preparation. The geometry of the joint preparation directly affects the penetration depth, heat distribution, weld metal behavior, and the presence of welding defects. This paper presents a technical review of weld joint designs, welding process classifications, and welding positions in accordance with EN ISO 9692 series, EN ISO 4063, and EN ISO 6947 standards.
