In this study, Aluminium 6082-T6 plates having 1.0 mm thickness were joined by magnesium-based (AlMg5) wire in cold metal transfer technique. The specimens were prepared in butt joint form. Argon was used as shielding gas and joining operations were done at gas flow speed of 13 l/min. The joining operations were carried out during four different working times of 25, 30, 35, 40 and 45 seconds. Tensile properties of joints were determined and macro-structures of joints were investigated in order to evaluate the joinability of Aluminium 6082-T6 alloy by cold metal transfer technique. Finally, the micro-hardness values of specimens were measured.
Bu çalışmada, 1,0 milimetre kalınlığa sahip Alüminyum 6082-T6 plakaları magnezyum esaslı (AlMg5) teliyle soğuk metal transferi yöntemiyle birleştirilmiştir. Numuneler, alın birleştirme formunda hazırlanmıştır. Koruyucu gaz olarak argon kullanılmıştır ve birleştirme işlemleri 20o çalışma açısıyla yapılmıştır. Soğuk metal transferi yöntemiyle farklı gaz basınçlarında kaynağı yapılan Alüminyum 6082 parçaların çekme dayanımı değerleri belirlenmiştir, sertlik değerleri ölçülmüş ve makro yapıları optik mikroskopta incelenmiştir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
