Abstract

La soldadura por frío entre superficies dentadas es lograda presionando una chapa de aluminio deformable fácilmente por una superficie dentada de un componente más duro. El proceso requiere la limpieza exacta de las chapas en el área de contacto. El empalme se logra solamente por grande deformación plástica del componente del aluminio, que entra entre los dientes del más duro, hecha de cobre, o de acero carbón o inoxidable. El papel presenta el modelo 2D por elemento finito del proceso: Los resultados como tensión elemental y las tensiones en el área de contacto en el componente de aluminio fueron discutidos y comparados con experimentos. Se presentan también la deformación y/o las grietas del aluminio que fluye durante presionar entre los dientes del material más duro, a diversas grados de deformación. El uso industrial más importante del proceso es en electrotécnica, para los empalmes disímiles de aluminio-cobre.-Cold welding on cogged surfaces is achieved by pressing an easy deformable sheet of aluminium on a cogged surface of a harder component. The process requires sheets accurate cleaning in the contact area, where the cold welding is expected to occur. The joint was obtained only by large plastic deformation of the aluminium component on the harder one, made from copper, or carbon/stainless steel. The paper presents the 2D Finite Element Method Model of the process; results as aluminium component elementary strain and stresses in the contact area were discussed and compared with experiments. The aluminium flowing during pressing into the harder material cogs at different deformations, its deformation or cracking are presented, as too. The process industrial application in electrotechnics, to obtaining dissimilar joints of aluminium-copper, is of high importance due to the coupled materials electric properties.
