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.
