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.

0 0 Expert
Automated Product Structure Creation in CATIA V5 Using Excel + Smart Property Update In this video, we demonstrate a complete workflow for generating a product structure in CATIA V5 using a simple Excel table. By entering the part number, description, revision, and assembly level, the macro automatically builds the correct hierarchical structure inside CATIA. We then create a basic part, define its dimensions, assign material and sheet metal thickness, and use a custom macro to update part properties like material, thickness, and revision directly from the Excel input. The video also shows how parameter changes are reflected instantly through automated updates — keeping your design, documentation, and data fully synchronized. 🎯 Ideal for design engineers working with large assemblies and standardization workflows. 🔧 Key Features: Auto-generation of CATIA product structures from Excel Sheet metal part creation with parameter definition Automated metadata (properties) update Live synchronization of parameter changes

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.
