“…AA 6013 aluminum alloy, also known as an aluminum-magnesium-silicon-copper alloy is widely used in aerospace applications, automotive and aircraft industries [1][2][3]. AA 6013 is evaluated to be a promising aluminum alloy in producing fuselage panels, leading and trailing edges, and engine cowlings due to its improved formability feature, high corrosion resistance and low density [4,5].…”

In this study, AA 6013 aluminum plates were butt‐welded with friction stir welding via pin offset technique. Macrostructural observations revealed that kissing bonds, originated from the broken oxide layers, were found to occur in the welded joints. The fracture location of welded joints after tensile tests was found to be outside the joint area, revealing that kissing bonds which were formed in the stir zone exhibited no detrimental effect on the mechanical properties of joints. Microstructural observations revealed that phases belonging to Mg2Si, Al4Cu2Mg8Si7 and Al(MnFe)Si were observed in the x‐ray diffraction pattern of friction stir welded joints. The highest tensile strength with a value of 206 MPa was achieved with the process parameters of 1.5 mm pin offset towards the advancing side and 500 min−1 tool rotational speed, leading the ratio of tensile strength of joint to ultimate tensile strength of base metal, also known as joint efficiency, to reach 74 %.

“…The ability of a steel body structure to deliver weight savings is limited, so the use of aluminium in auto body structures is increasing, and is projected to expand further in the next decade [3]. Owing to their low density and good mechanical properties, aluminium alloys are increasingly being employed in many important manufacturing areas, such as the automobile industries, aeronautics and the military [4][5][6]. Friction-stir welding (FSW) and laser beam welding (LBW) are noteworthy for their present use in commercial aircraft manufacturing [7][8][9][10][11].…”

“…Friction-stir welding (FSW) and laser beam welding (LBW) are noteworthy for their present use in commercial aircraft manufacturing [7][8][9][10][11]. LBW has accounted for a 5% reduction in the weight of Airbus A300 series structures and has also been employed to join some parts of the fuselage [4]. LBW was used to join critical parts in the fuselage in order to mitigate possible materials problems.…”

This research work aims at finding the optimum process parameters for the laser welding of AA7020 aluminium alloys. The use of 7xxx series alloys is limited because of weldability problems, such as hot cracking, porosity, and softening of the fusion zone despite its higher specific strength-to-weight ratio. AA7020 aluminium alloy was welded while varying the process parameters so as to obtain optimal welding efficiency. The welded samples were analysed to reveal the microstructure, defects, and mechanical properties of the welded zone. The samples were prepared from a plate of AA7020, which was hot rolled at a temperature of 470 • C to a thickness of 1 mm. The welding was carried out at an overlap of 0.25 mm, duration of 14 ms and argon shield gas flow rate of 15 L/min. Process parameters, such as peak power, welding speed, and pulse shaping, were varied. The samples were welded with Al-5Ti-B and Al-5Mg as filler metals. The welding speed, peak power, and pulse shaping have a great influence on the weldability and hot cracking susceptibility of the aluminium alloy. Al-5Ti-B improves the microstructure and ultimate tensile strength of AA7020 aluminium alloy.

“…As trincas de solidificação podem ocorrer em ligas de alumínio com adição de elementos de liga como Mg, Si e Cu [10]. Muitas ligas tratáveis termicamente, por exemplo, aquelas das classes AA2000 e AA6000, são susceptíveis ao surgimento de trincas durante a soldagem [11]. Este tipo de trinca ocorre quando a fração de líquido interdendrítico não suporta as tensões atuantes durante os últimos estágios de solidificação, resultando nas chamadas trincas do tipo "linha de centro" ou "de cratera", oriundas do meio da zona de fusão.…”

Resumo O objetivo da presente contribuição é discutir o aparecimento das trincas a quente em três ligas de alumínio, AA2024, AA6063 e AA6013, soldadas a laser. Para tanto um laser do tipo Yb:fibra foi usado em condições de aportes térmicos diferentes. Os resultados indicam uma tendência ao trincamento em várias condições experimentais. No entanto, para os parâmetros de processo utilizados e para as ligas estudadas, observa-se que quando a liga possui entre 0,6% e 1% de silício a sensibilidade ao trincamento diminui.
