“…Several methods of joining steel to Al have already been investigated, involving solid state joining, [1][2][3][4][5] reactive wetting (interaction between solid steel and liquid Al) [6][7][8][9][10][11][12][13][14][15][16][17][18] or laser key hole welding. 19,20 The steel to Al solid state joining was studied using various processes, such as explosion welding, 1 friction welding, 2,3 and more recently friction stir welding.…”

“…Taking advantage of the high welding velocity of the process and of the resulting limited interaction times, liquid steel to liquid Al interaction by key hole mode [18][19][20] was investigated, with some interesting results. However, the best results were achieved by laser reactive wetting, involving an Al induced melting by heat conduction through the steel, 11,12 and more recently by direct laser melting of Al. 17,18 Authors [13][14][15][16]18 have also used filler wires with low melting temperature to limit the energy input to the assembly in order to reduce steel/Al interfacial temperature.…”

The joining of DC04 steel to 6016-T4 Al alloy is achieved by laser braze welding using a 4047 (Al12Si) filler wire and a brazing flux. The dissimilar joining is obtained both by welding the parent 6016 alloy to the 4047 filler wire, producing a continuous bonding without apparent macroscopic flaws, and by reactive wetting of the molten Al alloy on the solid steel, resulting in the formation of a thin layer of Fe-Al-Si intermetallic compounds at the steel/bead interface. The linear strength of the assemblies can be as high as 190 N mm 21 , with a failure generally located in the reaction layer of the steel/bead interface. Last, the strength of the assemblies is shown to increase linearly with the reaction layer width.

“…Nevertheless, studies using conduction laser welding have shown very good results. [60][61][62] The advantage of using conduction laser welding in this application is related to the stability of the process that allows a better control of the temperature in the interaction area between the aluminium and the steel. 61 The use of conduction mode welding on magnesium alloys has also been assessed.…”

“…In contrast, not many studies of laser butt welding of steel and aluminum alloy have been reported. Representative of such research is combined laser welding-brazing by Kreimeyer et al [3] and butt laser welding with compression by Iizuka et al [4,5]. Although the joint strength of steel/aluminum TWBs welded by laser welding have stayed at around 80 % of the base aluminum and aluminum alloy until now.…”

“…In these studies, deep drawing tests were also conducted, and limited drawing ratios from 1.7 to 1.9 have been obtained [1][2][3][4]. However, with these exceptions, there is still not enough research on formability, that is, the second problem of steel/aluminum TWBs.…”

Tailored blanks, especially semi-finished parts formed by welding steel and aluminum alloys, are being employed in the automobile industry to reduce the weight of automobiles. However, when dissimilar metals are welded, galvanic corrosion due to differences in ionization tendency occurs, decreasing the reliability of such welded products. In addition, the heat input when aluminum alloys are welded causes an aging problem. In this study, combined-cycle corrosion testing was performed for S45C/6000 series steel/aluminum alloys joined by friction welding. First, S45C steel pipes were joined to A6061-T6 and A6063-T6 aluminum alloy pipes by friction welding. Then, after combined-cycle testing, changes in appearance and joint strength were investigated as the number of cycles increased. In the natural aging test, test pieces were placed in a desiccator whose temperature was adjusted to about 20 °C with a humidity from 0 to 10 %. One piece was removed at predetermined time intervals and used in tensile testing. After tensile testing, fracture surfaces were observed with an optical microscope. For the S45C/A6061 friction- welded material, a decrease in tensile strength was found at the 36th cycle. It was confirmed that the strength of the S45C/A6063 friction-welded material decreased clearly at the 27th cycle. Any obvious changes in strength were not seen in specimens after 540 hours of natural aging.
