Abstract

trata-se de um método de soldagem por ponto resistivo com o qual uma junta soldada que tem propriedades de fratura antirretardo pode ser formada, sendo que o método é dotado de uma etapa para fornecer energização através de uma corrente de energização i1 (ka) enquanto uma pressão de soldagem p1 (kn) é aplicada a uma pluralidade de chapas de aço com o uso de um eletrodo de soldagem, uma etapa para fornecer energização através de uma corrente de energização ic (ka) ao longo de um período de tempo de resfriamento tc (s) enquanto a pressão de soldagem p1 é aplicada, uma etapa para transmitir uma pressão de soldagem p2 (kn) na pluralidade de chapas de aço com o uso do eletrodo de soldagem ao longo de um período de tempo de soldagem tf (s) enquanto energiza o eletrodo de soldagem com uma corrente condutiva i2 (ka) e imediatamente após elevar e reduzir a pressão de soldagem em dois ou mais ciclos nos quais uma pressão de soldagem p3 (kn) é aplicada ao longo de um período de tempo de pressão de soldagem ti (s), uma etapa para aplicar a pressão de soldagem p2 ao longo do período de tempo de pressão de soldagem tf e uma etapa para liberar a pressão de soldagem e encerrar a energização, sendo que as etapas são fornecidas na ordem estabelecida. em que 0¿ic<i1, 0,3¿i2/i1<1,0, p2/p1¿1,2, tf¿0,2, p3<p2 e ti¿0,2.
