“…Definitely, in terms of mechanical properties, a higher quantity of alloying elements causes, will lead to an increase in mechanical properties which includes the rupture strength, yield strength and metal hardness. This factor will also greatly influenced impact strength values [12]. The behavior described by the hardness profiles revealed that Al weld using ER5356 indicated higher value compared to Al weld using ER4043.…”

“…The behavior described by the hardness profiles revealed that Al weld using ER5356 indicated higher value compared to Al weld using ER4043. From previous study, it is well defined that the thermal heat input experienced during welding process and with weld sequence of four layers becomes the main factors [12]. The extensive strength in A6061 weld using ER4043 compared to ER5356 can be attributed with the finer grain size and an even distribution of crystal structures in the weld regions [8] as shown in Fig.…”

“…Nas indústrias aeronáuticas e automobilísticas são freqüentes também as soldagens de alumínio por TIG, MIG, plasma, feixe de elétrons, laser, e por difusão (12,13,14,15) . (12) .…”

“…O ciclo térmico da zona afetada pelo calor, para ligas de alumínio endurecíveis por precipitação, causa a degradação de suas propriedades mecânicas devido a modificações microestruturais (13,15) . Obtém-se na soldagem uma região, adjacente ao cordão, solubilizada e com crescimento de grão e, após esta, uma região superenvelhecida, conforme a curva de resfriamento e a reação de formação dos precipitados.…”
