Bu çalışmada, AA2024 alüminyum alaşımı malzemelerin lazer kaynağı sırasında uygulanan farklı kaynak parametrelerinin çekme mukavemeti üzerindeki etkileri araştırılmış ve en uygun kaynak parametrelerini elde etmek için Taguchi ve ANOVA yöntemleri kullanılarak optimizasyonları yapılmıştır. Değişken kaynak parametreleri olarak lazer gücü, darbe süresi, ışın güç yoğunluğu ve darbe enerjisi kullanılmıştır. Sonuçlar, en düşük çekme dayanımının, 1800 W lazer gücünde, 5 ms darbe süresinde, 6000 W/mm2 ışın güç yoğunluğunda ve 9,5 Joule darbe enerjisi kullanılarak elde edildiğini, en yüksek çekme dayanımının ise 2600 W lazer gücünde, 6 ms darbe süresinde, 6500 W/mm2 ışın güç yoğunluğunda ve 9,5 Joule darbe enerjisi kullanılarak elde edildiğini göstermiştir. En yüksek çekme dayanımı (174 MPa) ile en düşük çekme dayanımı (113 MPa) sonuçları karşılaştırıldığında, en yüksek çekme dayanımının en düşük çekme dayanımından %53,98 daha yüksek olduğu bulunmuştur. S/N oranlarına göre, 2600 W lazer gücü, 6 ms darbe süresi, 7000 W/mm2 ışın güç yoğunluğu ve 10,5 Joule darbe enerjisinin AA2024 alüminyum alaşımının lazer kaynağı ile kaynak edilmesi için en optimum kaynak parametreleri olduğu anlaşılmıştır. ANOVA analizine göre ortalama çekme dayanımı üzerinde en etkili parametrenin lazer gücü (%82,45) olduğu belirlenmiştir.

Investigation of Mechanical Properties of Aluminum Alloys Welded by Laser Welding and Optimization of Welding Parameters Using Taguchi and ANOVA Methods

Öz

In this study, the effects of different welding parameters applied during laser welding of AA2024 aluminum alloy materials on the tensile strength were investigated and their optimizations were made using Taguchi and ANOVA methods to obtain the most suitable welding parameters. The variable welding parameters such as laser power, pulse duration, beam power density and pulse energy were used in the study. As a result, it was concluded that the lowest tensile strength was obtained when 1800 W laser power, 5 ms pulse duration, 6000 W/mm2 beam power density and 9.5 Joule pulse energy were used, while the highest tensile strength was obtained using 2600 W laser power, 6 ms pulse duration, 6500 W/mm2 beam power density and 9.5 Joule pulse energy. When the results of the highest tensile strength (174 MPa) and the lowest tensile strength (113 MPa) were compared, it was found that the highest tensile strength was 53.98%, which was higher than the lowest tensile strength.
