Tubo Duplex 2205<\/a> Soldagem Os mais comumente usados s\u00e3o SMAW, GTAW, SAW.<\/h2>\n

Em geral, FCAW n\u00e3o \u00e9 usado da melhor maneira, \u00e9 feio, dif\u00edcil de controlar e a entrada de calor \u00e9 grande, e GMAW tamb\u00e9m n\u00e3o \u00e9 usado.<\/p>\n

\"Soldagem<\/a><\/p>\n

Boa soldabilidade e baixa tend\u00eancia ao craqueamento t\u00e9rmico. Geralmente, n\u00e3o h\u00e1 necessidade de pr\u00e9-aquecer antes da soldagem, nenhum tratamento t\u00e9rmico ap\u00f3s a soldagem e soldagem com a\u00e7o diferente, como a\u00e7o inoxid\u00e1vel austen\u00edtico 18-8 ou a\u00e7o carbono. Em termos de processo, o processo de soldagem do a\u00e7o inoxid\u00e1vel austen\u00edtico comum \u00e9 suficiente.<\/p>\n

Para obter uma propor\u00e7\u00e3o consider\u00e1vel de p\u00f3s-soldagem<\/a> Na estrutura, \u00e9 fundamental conhecer a energia da linha ao soldar o a\u00e7o duplex 2205. Ela n\u00e3o deve ser muito grande ou muito pequena. Para evitar que o crescimento do gr\u00e3o seja muito r\u00e1pido ou grosseiro, controle a entrada de calor e tente levar a corrente de soldagem a um ponto pequeno. Sugere-se que o teor de ferrita seja medido durante a soldagem e ap\u00f3s a soldagem. Se houver um acordo t\u00e9cnico, ele dever\u00e1 ser avaliado de acordo com o acordo t\u00e9cnico!<\/p>\n

Em um determinado intervalo, a corrente deve ser pequena. Ao soldar, preste aten\u00e7\u00e3o ao arco n\u00e3o muito longo, caso contr\u00e1rio, ser\u00e1 f\u00e1cil ventilar.<\/p>\n

Os a\u00e7os duplex t\u00eam v\u00e1rias tend\u00eancias de fragilidade e n\u00e3o devem ser usados em condi\u00e7\u00f5es de trabalho acima de 300 graus.<\/p>\n

O g\u00e1s de prote\u00e7\u00e3o n\u00e3o pode ser usado com Ar + Co2. Uma vez que uma das caracter\u00edsticas mais importantes do a\u00e7o duplex \u00e9 seu conte\u00fado de nitrog\u00eanio, \u00e9 recomendado o uso de nitrog\u00eanio Ar + 1 ~ 3%, e o g\u00e1s de prote\u00e7\u00e3o posterior \u00e9 recomendado para uso de nitrog\u00eanio puro.<\/p>\n
