Abstract in Portuguese
Este trabalho aborda o mecanismo de desenvolvimento das tensões residuais longitudinais paralelas ao cordão de solda, na soldagem a topo de chapas finas. Inicialmente discute-se o atual estágio de desenvolvimento das análises experimentais e teóricas dentro deste campo. A seguir apresenta-se um modelo de cálculo para estima das tensões residuais longitudinais. Finalmente, este modelo é verificado com auxílio de resultados experimentais obtidos pelo autor. Um estudo comparativo é desenvolvido para as distribuições de temperaturas e de tensões residuais.

Abstract in English
This paper deals with the developed of longitudinal stress distribution in thin plates, due to a butt weld. Initially, the state-of-the-art of experimental and theoretical analysis was discussed. Then a computer program was proposed to estimate longitudinal stress distribution. Finally, the numerical results were compared to some experimental data in terms of temperatures and longitudinal stresses.
