Abstract

trata-se de uma junta soldada a ponto e método de soldagem a ponto com os quais resistência à tração cruzada (cts) alta pode ser obtida mesmo se uma ou mais chapas de aço de alta resistência forem incluídas. é fornecida uma junta soldada a ponto (1) que inclui uma pluralidade de chapas de aço, em que a uma ou mais chapas de aço são chapas de aço de alta resistência com uma resistência à tração de 750 a 2.500 mpa, e deixar o plano a ser um plano que sobrepõe uma chapa de aço de alta resistência s1 disposta no lado mais externo em um corte transversal na direção de espessura de chapa da chapa de aço e outra chapa de aço (1b) e deixar o plano b ser um plano paralelo ao plano a e que passa através de um ponto a 1/2 da distância entre uma posição de extremidade de lentilha de solda e no lado de chapa de aço de alta resistência s1, que está em uma linha l1 na direção de espessura de chapa, e uma interseção o entre o plano a e a linha l1, o valor médio para largura de um bloco que é constituído de martensita em ripa é 0,5 a 7,0 µm em uma região quadrada sa que é incluída em uma zona afetada por calor (4) com a chapa de aço de alta resistência s1 como o material de base e tem um lado de 30 µm em que o centro é uma interseção x de uma linha l2, que é paralela a uma linha tangente em qualquer posição na linha de extremidade de lentilha de solda nel ensanduichada entre o plano a e plano b e é separada 250 µm no lado de zona afetada por calor em relação à linha tangente e uma linha l3 perpendicular à l2.
