This paper presents a comprehensive study of the metallurgical challenges of welding dissimilar metals. It also describes the important factors in dissimilar welding which need to be considered for automotive applications. It further investigates effective approaches to overcome these present challenges. Steels, aluminum alloys, and magnesium alloys are widely used metals in car bodies. However, it is difficult to weld these dissimilar metals and achieve good joint quality, due to their inherent disparate properties. The formation of brittle, crack sensitive and corrosion susceptible intermetallic phases is the main obstacle to dissimilar weld quality. Various approaches have been attempted by many researchers to enhance the performance of dissimilar welds. The most notable efforts include the application of interlayers, cover plate, least heat input, a combination of welding and mechanical joining, and alloying elements of filler metals. Based on considerations of joint performance, production cost and time, present industry infrastructure, and so on, the most effective and feasible approaches were identified which required the least amount of heat input, and the appropriate filler metal alloying elements.

“…The main challenge of joining dissimilar materials [2][3][4] with differences in properties is the formation of intermetallic compounds (IMCs), which are brittle. There is also a high probability of crack formation due to residual stress generation.…”

Distribution of temperature during the welding process is essential for predicting and realizing some important welding features such as microstructure of the welds, heat-affected zone (HAZ), residual stresses, and their effects. In this paper, a numerical model was developed using COMSOL Multiphysics of dissimilar laser welding (butt joint) of AISI 316L and Ti6Al4V thin sheet of 2.5 mm thickness. A continuous mode (CW) fiber laser heat source of 300W laser power was used for the present study. A time-dependent prediction of temperature distributions was attempted. The heat source was assumed as a Hermit–Gaussian analytical function with a moving velocity of 120 mm/min. Both convective and radiant heat loss and phase change of the materials were considered for the analysis. In addition, variation of temperature-dependent material properties was also considered. The maximum and minimum temperature for the two materials at different times and the temperature in the different penetration depths were also predicted. It was found that the average temperature that can be achieved in the bottom-most surface near the weld line was more than 2400K, which justifies the penetration. Averages of maximum temperatures on the weld line at different times at the laser spot irradiation were identified near 3000K.The temperature fluctuation near the weld line was minimal and decreased more in the traverse direction. Scanning with a displaced laser relative to the interface toward the Ti6Al4V side reduces the maximum temperature at the interface and the HAZ of the 316L side. All of these predictions agree well with the experimental results reported in current literature studies.

Bu çalışmada nokta direnç kaynaklı DP1200 çeliğinin ideal çekme makaslama dayanımını elde etmek için farklı kaynak akımı ve elektrot basıncı parametrelerinin optimizasyonuna odaklanılmıştır. Kaynak prosesleri 5 kA ve 7 kA kaynak akımlarında, 2-6 bar elektrot basınçlarında gerçekleştirilmiştir. Kaynak parametrelerinin çekme makaslama dayanımı üzerindeki etkileri çoklu doğrusal regresyon analizi ile incelenmiştir. Yapılan bu analiz ile elde edilen korelasyon tablosu ve ANOVA analiz değerleri yorumlanmıştır. Kaynak parametrelerinin önem derecesi belirlenerek, çekme makaslama dayanımı üzerindeki etkileri karşılaştırılmış ve belirlenen etki değerlerine göre çoklu doğrusal regresyon modeli oluşturulmuştur. Deneysel sonuçlar çekme makaslama dayanımını etkileyen en önemli değişkenin kaynak akımı olduğunu göstermiştir. Kaynak akımı arttıkça çekme makaslama dayanımı artmıştır. Özellikle yüksek kaynak akımı değerinde, elektrot basıncının kritik değerine kadar çekme makaslama dayanımının arttığı, fakat kritik değerinin üzerinde dayanımda düşüş olduğu görülmüştür. Sıçramanın çekme makaslama dayanımı üzerinde negatif etkiye sahip olduğu gözlenmiştir.
