{"id":3176,"count":0,"description":"Les champignons de rail sont la partie sup\u00e9rieure d\u2019un rail. Ils soutiennent et guident les roues des wagons. Les champignons de rail peuvent \u00eatre endommag\u00e9s apr\u00e8s une p\u00e9riode tr\u00e8s courte en raison du patinage des roues d\u00fb \u00e0 une forte charge et \u00e0 des conditions telles que l\u2019acc\u00e9l\u00e9ration et le freinage. L\u2019usure m\u00e9tal-m\u00e9tal peut entra\u00eener des d\u00e9fauts de surface et de sous-surface qui, s\u2019ils ne sont pas trait\u00e9s, peuvent causer d\u2019autres d\u00e9g\u00e2ts au rail et occasionner la fermeture de la voie. La remise en \u00e9tat des champignons de rail au moyen d\u2019une technique de rechargement permet la restauration in-situ du rail, ou le recyclage des rails us\u00e9s dans un atelier, ce qui entra\u00eene une maintenance et des temps d\u2019arr\u00eat r\u00e9duits. Le d\u00e9ploiement de proc\u00e9d\u00e9s de soudage automatique ou semi-automatique offre une solution rentable par rapport au remplacement d\u2019un
