TIG ALIN KAYNAKLI ALÜMİNYUM BİRLEŞTİRMELERİN MİKROYAPI VE MEKANİK ÖZELLİKLERİNİN SKP VE T6 ISIL İŞLEMİ YOLUYLA KAYNAK SONRASI MODİFİKASYONU ÜZERİNE BİR ARAŞTIRMA

Fusion welding is a commonly applied manufacturing process in all fields of industry. Some imperfections (formation coarse-grained microstructure, decrease mechanical property, etc.) can occur especially the fusion welding-based fabrication aluminum alloys which have specific features, such as having high thermal conductivity, expansion coefficient, hydrogen solubility liquid state, and oxide layer on surface. Therefore, enhancement microstructure properties terms lifespan strength fusion-welded joints crucial for most applications. In study, effects friction stir processing (FSP) T6 heat treatment, post-weld processing, weld zone gas tungsten arc welded (GTAWed) AA6082 plates were investigated. The processings (FSP treatment) microstructural features analyzed via examination microhardness measurements tensile testing. It was observed that dendritic processed region (stir zone) bead destroyed fine-grained formed FSP. Additionally, findings showed input occurred during FSP led to broaden affected (HAZ) hardness wider region. also determined characteristics GTAWed joint increased but contrast, toughness decreased through treatment.
