Abstract

trata-se de um membro em formato de placa que é submetido ao flan-geamento, de acordo com a presente invenção, em que são desempenhadas as seguintes etapas: uma etapa de perfuração de perfuração do membro em formato de placa; uma etapa de expansão de orifício que submete o orifício perfurado formado na etapa de perfuração a um processo de expansão de orifício; uma etapa de reperfuração que submete a um processo de reperfuração uma porção periférica do ori-fício perfurado que foi pressionado e expandido na etapa de expansão de orifício; e uma etapa de formação de flange que forma uma parede vertical pressionando-se a porção periférica do orifício perfurado no-vamente, que é o orifício perfurado formado na etapa de reperfuração.
