“…Therefore, it is necessary to study the joining technique that can ensure high reliability. To obtain a high-quality joint between aluminum and steel, several welding processes such as laser beam fusion welding [5][6][7], dual-beam laser welding [8], and laser beam welding with pressure [9][10] have been investigated so far. However, fusion base metal could bring a large number of intermetallic compounds in the laser beam fusion welding and dual-beam laser welding process.…”

“…In particular, the process of joining the aluminum alloys with various types of steels has undergone widespread research due to its outstanding applicability in various structural components [7,8]. However, direct joining of aluminum alloys to steels accompanies various challenges due to tremendous differences in their thermo-physical properties such as coefficient of thermal expansion, specific heat and heat conductivity which can lead to formation of various defects [9][10][11]. In addition, iron and aluminum are metallurgically incompatible owing to their low solid solution miscibility, which can result in formation of various Fe x Al y brittle intermetallic compounds [9][10][11].…”

In addition, iron and aluminum are metallurgically incompatible owing to their low solid solution miscibility, which can result in formation of various Fe x Al y brittle intermetallic compounds [9][10][11]. Various joining methods including mechanical [2,5,12], solid state [2,4,5] and fusion joining [7,11,13], have been implemented to join aluminum alloys to steels.…”

“…Since laser welding has advantages such as local heat input, short process time and high flexibility compared with other welding processes, there has been considerable research on the welding of steel and aluminum. In the recent, the studies of keyhole welding (Torkamany, et al, 2010), laser welding-brazing (Dharmendra, et al, 2011), dual-beam YAG laser welding (Yan, et al, 2010), and thermal cycle during laser welding (Fan, et al, 2011) are carried out.…”
