A consistent lightweight concept necessitates the combination of different lightweight materials. Because of the significant weight reduction, multimaterial design is becoming more and more interesting for the transportation industry. Mixed material concepts are partially limited because of the insufficient deformation behavior of the joining seams. To overcome this limitation, a brazing process has been developed in which aluminium and steel can be joined, with an enhanced deformation behaviour. Tailored hybrid blanks with deep drawing ratios of 1.9 are possible. Process studies, metallographic analyses, and tensile tests were carried out for AA6016 sheets in combination with DX56D. The AA6016 surface has to be activated using a noncorrosive flux. Although it is possible to avoid melting of the aluminium base metal, intermetallic FeAl compounds occur and were characterized using energy dispersive x-ray analysis. It was proven that the intermetallic compounds affect the mechanical characteristics of the seam. During tensile tests, butt seams show approximately 70% of the strength of the weaker base metal. The results of cupping tests show the ultimate possibility of using tailored hybrid blanks in a various number of applications.

“…Shah et al [9] and Razak [10] have conducted the preheating method on tungsten inert gas (TIG) dissimilar welding AA1100-SUS304 and AA6061-SUS304, respectively, and both results have shown an increase in the tensile strength of the joint when steel is preheated up to 150 ˚C. Other researches by Kreimeyer and Vollertsen [11] as well as Bang et al [12] also suggested a secondary heat source in order to preheat the steel counterpart prior to welding to enhance the joint strength output.…”

Abstract. This paper investigates the parameter optimization of a preheating method on stainless steel SUS304 prior to aluminium-stainless steel dissimilar welding. The welding method used was metal inert gas (MIG) with butt joint type weld. The Taguchi L9 orthogonal array was used to investigate the optimum parameter, while the mechanical strength was investigated using tensile test. Optimum levels of the process parameters were analyzed using the Taguchi parametric design approach. Parameter analysis of the tensile test results indicate that the preheated specimen with 90 °C have the maximum ultimate tensile strength of 111.27 MPa. This value is in close proximity to the calculated value of 109.02 MPa with 2% error. Through analysis of variance (ANOVA), the welding current was the dominant contributing factor with 40%. It can be concluded that the highest tensile value (111.27 MPa) for AA6061-SS304 dissimilar welding was obtained using 90 °C preheating, voltage of 17.5 V and current of 110 A of current.
