La plus grande caract\u00e9ristique de la construction hivernale est, je pense, que la temp\u00e9rature est relativement basse, dans l'op\u00e9ration de soudage il faut faire attention \u00e0 la temp\u00e9rature, il faut d\u00e9terminer la temp\u00e9rature de la position de soudage avant le soudage, dans le cas o\u00f9 la temp\u00e9rature est inf\u00e9rieure aux exigences du processus, le m\u00e9tal de base doit \u00eatre pr\u00e9chauff\u00e9 avant le soudage. Il convient de pr\u00eater attention au probl\u00e8me d'isolation thermique apr\u00e8s le soudage en hiver. Il convient de veiller \u00e0 ce que les mat\u00e9riaux restent secs en cas de pluie ou de neige. Des mesures doivent \u00eatre prises pendant les travaux de soudage en hiver. Si la temp\u00e9rature est sup\u00e9rieure \u00e0 -5 degr\u00e9s Celsius, proc\u00e9dez \u00e0 un s\u00e9chage et \u00e0 une isolation conventionnels. Si la temp\u00e9rature est trop basse ou si le panneau est trop \u00e9pais, il faut pr\u00e9chauffer et faire attention \u00e0 l'isolation entre les couches.<\/p>\n\n\n\n

Principales mesures techniques pour la construction hivernale<\/p>\n\n\n\n

1. Le soudage des tuyaux doit \u00eatre pr\u00e9chauff\u00e9 en stricte conformit\u00e9 avec les exigences, et le tuyau doit \u00eatre plac\u00e9 dans un atelier ferm\u00e9 pour \u00eatre chauff\u00e9 \u00e0 l'avance.<\/p>\n\n\n\n

2. lorsque la temp\u00e9rature ambiante est inf\u00e9rieure \u00e0 5\u2103, elle ne convient pas \u00e0 l'\u00e9preuve hydraulique ; l'eau de la canalisation qui a \u00e9t\u00e9 soumise \u00e0 l'\u00e9preuve de la pression hydraulique doit \u00eatre \u00e9vacu\u00e9e \u00e0 temps et l'embouchure de la canalisation doit \u00eatre temporairement obstru\u00e9e.<\/p>\n\n\n\n

3. il faut essayer d'\u00e9viter de tester la pression du pipeline en hiver, si cela doit \u00eatre le cas, afin de minimiser la dur\u00e9e d'exposition du pipeline rempli d'eau \u00e0 l'environnement naturel, conform\u00e9ment aux exigences de la sp\u00e9cification, la dur\u00e9e du test doit \u00eatre aussi courte que possible, apr\u00e8s le test, il faut \u00e9vacuer l'eau du pipeline \u00e0 temps et maximiser le s\u00e9chage par soufflage.<\/p>\n\n\n\n

4. il convient d'augmenter autant que possible la pr\u00e9fabrication afin de r\u00e9duire la charge de travail li\u00e9e au soudage sur le chantier.<\/p>\n\n\n\n

5. La vitesse du vent pendant le soudage ne doit pas d\u00e9passer les dispositions suivantes ; dans le cas contraire, des mesures de protection contre le vent doivent \u00eatre prises :<\/p>\n\n\n\n

Une soudure manuelle \u00e0 l'arc est de 8m\/s ;<\/p>\n\n\n\n

B Soudage \u00e0 l'arc \u00e0 l'hydrog\u00e8ne, soudage au gaz carbonique 2m\/s<\/p>\n\n\n\n

6. l'humidit\u00e9 relative de l'environnement \u00e0 moins d'un m\u00e8tre de l'arc de soudage ne doit pas \u00eatre sup\u00e9rieure \u00e0 90%.<\/p>\n\n\n\n

7. la temp\u00e9rature de l'environnement de soudage doit pouvoir garantir que les pi\u00e8ces \u00e0 souder n\u00e9cessitent une temp\u00e9rature suffisante et que les comp\u00e9tences du soudeur ne seront pas affect\u00e9es.<\/p>\n\n\n\n

8. Exigences relatives au proc\u00e9d\u00e9 de soudage :<\/p>\n\n\n\n

A Lorsque la temp\u00e9rature ambiante est inf\u00e9rieure \u00e0 0\u2103, les joints de soudure sans exigences de pr\u00e9chauffage, \u00e0 l'exception de l'acier inoxydable aust\u00e9nitique, doivent \u00eatre pr\u00e9chauff\u00e9s \u00e0 plus de 15\u2103 dans un rayon de 100 mm autour du point de soudure initial.<\/p>\n\n\n\n
