About the Book

Uma das finalidades do pré-aquecimento na soldagem é reduzir a taxa de resfriamento da junta a ser soldada, com consequente minimização da formação de fases frágeis. Esta prática é usualmente realizada em uma região relativamente extensa no entorno da junta, eventualmente causando alterações indevidas nas propriedades mecânicas e metalúrgicas do metal base, além de desperdiçar energia e tempo. Entretanto, o aquecimento localizado na junta também tem a função de auxiliar na fusão do metal base, fazendo com que este alcance temperaturas próximas à fusão do material. Esse pré-aquecimento pode favorecer o aumento da penetração do cordão de solda. Em juntas de chapas mais espessas, pode ser descartada a usinagem de chanfro em alguns casos, e podem ser alcançadas maiores velocidades do processo de soldagem. Desta forma, neste trabalho foi utilizado um equipamento de aquecimento indutivo para aquecer localmente a zona a ser soldada, visando avaliar a microestrutura formada e o perfil de durezas encontrado para os parâmetros variados. Os parâmetros de montagem e de operação foram avaliados quanto à sua influência na geometria do cordão de solda.
