                         Ve{\'{\i}}culos Lan{\c{c}}adores de Sat{\'e}lites. As 
                         jun{\c{c}}{\~o}es foram obtidas pelo processo de soldagem por 
                         fric{\c{c}}{\~a}o rotativa convencional, que combina o calor 
                         gerado entre o atrito de duas superf{\'{\i}}cies e 
                         deforma{\c{c}}{\~a}o mec{\^a}nica. Foram realizados testes de 
                         soldagem com diferentes par{\^a}metros de processo e medida a 
                         temperatura na interface de liga{\c{c}}{\~a}o. Os resultados 
                         desses testes foram analisados por meio de ensaios mec{\^a}nicos 
                         de tra{\c{c}}{\~a}o, microdureza Vickers, ensaios 
                         metalogr{\'a}ficos e MEV-EDX. A resist{\^e}ncia da junta variou 
                         com o aumento do tempo de fric{\c{c}}{\~a}o e com a 
                         utiliza{\c{c}}{\~a}o de diferentes valores de press{\~a}o. 
                         Foram obtidas jun{\c{c}}{\~o}es com propriedades mec{\^a}nicas 
                         superiores a da liga de alum{\'{\i}}nio AA 1050 no tempo de 
                         fric{\c{c}}{\~a}o de 34 segundos, com a fratura ocorrendo no 
                         alum{\'{\i}}nio longe da interface de liga{\c{c}}{\~a}o. A 
                         temperatura monitorada na regi{\~a}o de contato entre os dois 
                         materiais durante o processo apresentou um valor de 376C, 
                         coincidindo com a faixa de temperatura de forjamento {\'a} quente 
                         para o alum{\'{\i}}nio AA 1050 (315C - 430C). A an{\'a}lise 
                         feita pelo EDX na interface da jun{\c{c}}{\~a}o mostra que 
                         ocorre interdifus{\~a}o entre os principais elementos 
                         qu{\'{\i}}micos dos materiais envolvidos. O processo de soldagem 
                         por fric{\c{c}}{\~a}o convencional demonstra ser um {\'o}timo 
                         m{\'e}todo para obten{\c{c}}{\~a}o de jun{\c{c}}{\~o}es entre 
                         materiais dissimilares que n{\~a}o s{\~a}o poss{\'{\i}}veis

                         of this work is the development of solid state joints of 
                         dissimilar material AA 1050 aluminum alloy and AISI 304 stainless 
                         steel, which can be used in pipes of tanks of liquid propellants 
                         and other pipes of the Satellite Launch Vehicle. The joints were 
                         obtained using welding process by conventional rotary friction, 
                         which combines the heat generated from friction between two 
                         surfaces and mechanical deformation. Tests were conducted with 
                         different welding process parameters and measured the temperature 
                         at the interface of bonding. The results of these tests were 
                         analyzed by means of tensile tests, Vickers microhardness, 
                         metallographic tests and SEM-EDX. The strength of the joints 
                         varied with increasing friction time and the use of different 
                         pressure values. Joints with superior mechanical properties of the 
                         AA 1050 aluminum alloy could be obtained at a frictional time of 
                         34 seconds, with the fracture occurring in the aluminum away from 
                         the interface of bonding. The temperature monitored in the region 
                         of contact between the two materials during the process had a 
                         value of 376C, coinciding with the temperature range for hot 
                         forging of the AA 1050 aluminum alloy (315C - 430C). The 
                         analysis by EDX at the interface of the junction shows that occur 
                         interdiffusion between the main chemical components of the 
                         materials involved. The welding process by conventional rotary 
                         friction proves to be a good method for obtaining joints between 
                         dissimilar materials that are not possible by the fusion welding 
                         processes.",
