“…In the welding brazing process, the heat source is mainly used for melting the base metal with lower melting point, and then the brazing joint was formed by wetting of molten metal [4]. There are various investigations on the aluminum and steel welding brazing process, including laser beam welding [4][5][6], CMT (cold metal transfer) welding [7][8][9], and TIG (tungsten inert gas) arc welding [10,11]. However, there are two major issues that have limited the welding brazing of steel and aluminum; one is the poor wetting ability of weld pool, and the other is the generation of brittle and hard intermetallic compounds (IMC), which can introduce deleterious effect on the welded joints [12].…”

Using laser beam as main heat source, and trailing arc as an assisted role, aluminum alloy was joined to galvanized steel in a butt configuration. Under suitable welding parameters, a sound welding seam was obtained. The interface intermetallic compounds layer and wetting behavior of weld joint were studied. The assisted arc can improve the wetting and spreading ability of weld pool duo to large temperature field. There are two different types of IMCs: near to the steel side one is Fe2Al5 with tooth-like shape and near to the weld seam side is the other one Fe4Al13 with flocculent-like shape. The highest tensile strength can reach 163 MPa when the fracture occurred at the weld seam.

“…Liu et al [20] reported that the weld width increased with increasing laser power. At a higher laser power of 2250 W and a feeding speed of 4.53 g/min, a better brazed joint was obtained.…”

“…A macro-metallographic analysis showed that the filler alloy wets the base metal very well, and the wetting angle primarily depends on the heat input. In addition, Liu et al [20] investigated the effect of using pure Al powder in the fabrication of a laser-brazed joint between galvanized steel of 0.8 mm thickness and A5052 of 1.5 mm thickness. The powder effectively reduced the generation of holes and pores in the weld zone.…”

The paper provides experimental details of the welding and specific examples of welding aluminum welding battery cans and conductive tabs for battery pack manufacture. In this study, we provide experimental details of a process for joining dissimilar materials used in sealing battery parts. A laser brazing technique was used for the lap joining of aluminum alloy and a deep drawing quality stainless steel, with an Al-Si filler metal. These materials are commonly used in battery applications, as materials for the cap plate, tab plate and can. The relationships among the width of the brazed zone, formation of intermetallic compounds (IMCs), shape of the joint interface, and joint strength were systematically investigated with respect to the laser power and filler wire feeding rate. When a low and medium laser power (1.2-2.0 kW) was applied, the joint strength was very low, and fracture occurred across the band-shaped IMC layer. With a further increase in the applied laser power (2.2-2.8 kW), a new needle-like IMC composed of Al13Fe5 with a monoclinic crystal structure was formed, and it penetrated the brazed zone. In addition, the width of the brazed zone increased due to the partial melting of the aluminum. The joint efficiency under a high laser power condition was 70% compared to that of the base material. Fractures occurred alternately along the needle-shaped IMC and filler metal zone. Since the fracture propagated along the needle-like IMCs inside the brazed zone, the peak load was higher than that of the band-shaped IMCs.

“…The necessity for joints between dissimilar materials often arises in functionally complex industrial applications, economic and environmental concerns (Torkamany et al, 2010;Guo et al, 2014;Liu et al, 2015). For instance, the combination of steel with aluminum provides fuel-efficiency by reducing the weight of construction (Miller et al, 2000;Torkamany et al, 2010;Ahsan et al, 2016).…”

“…Al-Fe phase diagram reveals that the solid solubility of iron in aluminum is quite low (Torkamany et al, 2010;Su et al, 2014). Hence, the formation of brittle intermetallic phases such as Fe 3 Al, FeAl, FeAl 2 , Fe 2 Al 3 , Fe 2 Al 5 and FeAl 3 are promoted especially at high temperature (Potesser et al, 2006;Torkamany et al, 2010;Cao et al, 2013;Zhou and Lin, 2014;Liu et al, 2015). Fe-Al intermetallic phases are required for an effective joint between aluminum and steel, nevertheless thickness of this IMC layer should be kept below 10 µm to supply technical demands (Jácome et al, 2009;Cao et al, 2014a).…”

En este estudio, la soldadura por solapamiento de AA5754 y chapas de acero galvanizado se llevó a cabo mediante el método de transferencia de metal en frío (CMT) utilizando un hilo de relleno ER4043 (AlSi5). Se investigó el efecto del aporte de calor sobre la formación de la capa de compuesto intermetálico (IMC) entre el acero y el aluminio. Las propiedades mecánicas de las juntas se determinaron mediante ensayos de tracción y dureza y también aplicando la prueba de nano indentación a la capa intermetálica. Las composiciones químicas de IMC se analizaron mediante EDX y se detectó la formación de fases Al7.2Fe1.8Si y Fe2Al5. La formación de la fase Fe2Al5 fue perjudicial para la fiabilidad de la articulación, aunque su resistencia mecánica es superior.
