Abstract:

 In this study, cold rolled Strenx 700 CR steel with a minimum yield strength of 700 MPa, which is typically used in load bearing structures to produce stronger and lighter structures, is butt welded with Nd:YAG laser welding. The effect of welding factors on tensile strength is investigated by using laser power rate 20, 40 and 60, pulse duration 2, 4 and 6 ms and pulse frequency 3, 5 and 7 hz. By using Taguchi L9 orthogonal experimental design, the number of experiments, which should be 27 when full factorial, is reduced to 9 experiments. The tensile strength test results are optimized by the Taguchi methods larger is better control characteristic. The optimum test combination for maximum tensile strength is determined as A3B2C2 60-4 ms-5 hz. The effect of the welding factors on the tensile strength results is analyzed using the analysis of variance ANOVA method and it is found that the most effective factor is the laser power rate with 84.26.

 Bu çalışmada, daha güçlü ve hafif yapılar üretmek için tipik olarak yük taşıyıcılarda kullanılan ve minimum 700 MPa akma dayanımına sahip soğuk haddelenmiş Strenx 700 CR çeliği Nd:YAG lazer kaynağı ile alın şeklinde birleştirilmiştir. Birleştirme işlemlerinde; lazer güç oranı 20, 40 ve 60, darbe süresi 2, 4 ve 6 ms ve darbe frekansı 3, 5 ve 7 hz kullanılarak, kaynak faktörlerinin çekme dayanımına etkisi incelenmiştir. Taguchi L9 ortogonal deney tasarımı kullanılarak tam faktöriyel iken 27 adet olması gereken deney sayısı 9 adet deneye indirgenmiştir. Çekme dayanımı testi sonuçları Taguchi metodunun en büyük-en iyi kontrol karakteristiği ile optimize edilmiştir. Maksimum çekme dayanımı için belirlenen optimum test kombinasyonu, A3B2C2 60-4 ms-5 hz olarak belirlenmiştir. Çekme dayanımı sonuçlarına, kaynak faktörlerinin etkisi ise varyans analizi ANOVA metodu kullanılarak incelenmiş ve en etkin faktör 84.26 ile lazer güç oranı olduğu tespit edilmiştir.
