Abstract

"PROCESSO DE SOLDAGEM ELéTRICA DE AçOS DE BAIXA E ALTA LIGA, TEMPERADOS OU NãO, E BIMETAIS, PARA OBTENçãO DE TEXTURA DETERMINADA SEM TRATAMENTO TéRMICO". No qual , a 1<a> camada (1) destina-se a revestir o chanfro e raiz do chanfro com eletrodo de cristalização da solda depositada, a referida solda sendo adequada para obtenção de textura austenítica mais ferrítica. Com a 2<a> camada (2), promove-se o enchimento do chanfro com eletrodo de cristalização da solda depositada, obtendo-se textura perlítica ou perlítica mais trostita, enquanto que, nas 3<a> e 5<a> camadas (3, 5), usa-se eletrodo de cristalização da solda depositada para obtenção de textura austenítica mais ferrítica. Na 4<a> camada (4), usa-se eletrodo de cristalização da solda depositada para obtenção de textura sorbítica mais bainítica, e na 6<a> camada (6), usa-se eletrodo de cristalização da solda depositada para obtenção de textura bainítica.
