Abstract

trata-se de um método de soldagem sobreposta de chapa de aço que compreende: uma etapa de soldagem por ponto em que uma junta (110) é formada entre um primeiro membro de chapa de aço (1x) e uma parte de flange (2) de um segundo membro de chapa de aço (1y) que inclui a parte de flange (2) e uma parede vertical (4), a junta formada por soldagem por ponto em um estado em que a parte de flange (2) é sobreposta ao primeiro membro de chapa de aço (1x); e uma etapa de soldagem a laser na qual, após a etapa de soldagem por ponto, um cordão de solda (120) é formado por soldagem a laser em uma região entre um ponto de extremidade de curva (3a) da parede vertical (4) e a junta (110). o cordão de solda (120) tem uma dimensão de comprimento (l) que é igual ou maior que o diâmetro (dn) da junta (110), e uma dimensão de largura (w) de 0,5 a 3,0 mm.
