Tuyau Duplex 2205<\/a> Soudage Les plus couramment utilis\u00e9s sont SMAW, GTAW, SAW.<\/h2>\n

En g\u00e9n\u00e9ral, le FCAW n'est pas utilis\u00e9 au mieux, il est moche, difficile \u00e0 contr\u00f4ler et l'apport de chaleur est important, et le GMAW n'est pas non plus utilis\u00e9.<\/p>\n

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

Bonne soudabilit\u00e9 et faible tendance au craquage thermique. G\u00e9n\u00e9ralement, il n'y a pas besoin de pr\u00e9chauffer avant le soudage, pas de traitement thermique apr\u00e8s soudage et de soudage avec des aciers dissemblables tels que l'acier inoxydable aust\u00e9nitique 18-8 ou l'acier au carbone. En termes de proc\u00e9d\u00e9, le proc\u00e9d\u00e9 de soudage de l'acier inoxydable aust\u00e9nitique ordinaire est suffisant.<\/p>\n

Afin d'obtenir une proportion consid\u00e9rable de post-soudure<\/a> En ce qui concerne la structure du soudage, il est essentiel de conna\u00eetre l'\u00e9nergie de la ligne lors du soudage de l'acier duplex 2205. Elle ne doit \u00eatre ni trop grande ni trop petite. Afin d'\u00e9viter une croissance trop rapide ou trop grossi\u00e8re du grain, il convient de contr\u00f4ler l'apport de chaleur et d'essayer de r\u00e9duire le courant de soudage. Il est sugg\u00e9r\u00e9 de mesurer la teneur en ferrite pendant et apr\u00e8s le soudage. S'il existe un accord technique, il doit \u00eatre \u00e9valu\u00e9 conform\u00e9ment \u00e0 l'accord technique !<\/p>\n

Dans une certaine plage, le courant doit \u00eatre faible. Lors du soudage, faites attention \u00e0 l'arc pas trop long, sinon il sera facile \u00e0 ventiler.<\/p>\n

Les aciers duplex ont diverses tendances \u00e0 la fragilit\u00e9 et ne doivent pas \u00eatre utilis\u00e9s dans des conditions de travail sup\u00e9rieures \u00e0 300 degr\u00e9s.<\/p>\n

Le gaz protecteur ne peut pas \u00eatre utilis\u00e9 avec Ar+Co2. \u00c9tant donn\u00e9 que l'une des caract\u00e9ristiques les plus importantes de l'acier duplex est sa teneur en azote, il est recommand\u00e9 d'utiliser de l'azote Ar+1 ~ 3% et le gaz de protection arri\u00e8re est recommand\u00e9 d'utiliser de l'azote pur.<\/p>\n
