Avant la popularisation des applications laser, les t\u00f4les moyennes et \u00e9paisses en acier au carbone utilisent g\u00e9n\u00e9ralement des proc\u00e9d\u00e9s de d\u00e9coupe traditionnels tels que le coupage au plasma, le coupage \u00e0 la flamme et le coupage au jet d'eau \u00e0 haute pression, parmi lesquels le coupage au plasma est le repr\u00e9sentant. Ces derni\u00e8res ann\u00e9es, avec l'application et le d\u00e9veloppement de l'industrie de la d\u00e9coupe laser, les inconv\u00e9nients de la d\u00e9coupe plasma se sont progressivement refl\u00e9t\u00e9s.<\/p>\n\n\n\n

Le coupage au plasma est une m\u00e9thode de traitement qui utilise la chaleur d'un arc plasma \u00e0 haute temp\u00e9rature pour faire fondre localement le m\u00e9tal au niveau de l'incision de la pi\u00e8ce et \u00e9limine le m\u00e9tal en fusion \u00e0 l'aide de l'\u00e9lan du plasma \u00e0 grande vitesse pour former une incision.<\/p>\n\n\n\n

Pour le coupage au plasma, le courant de coupage de l'alimentation plasma est le param\u00e8tre le plus important du processus de coupage, qui d\u00e9termine directement l'\u00e9paisseur et la vitesse de coupe. Plus le courant est \u00e9lev\u00e9, plus l'\u00e9nergie de l'arc ainsi que la vitesse et l'\u00e9paisseur de coupe sont fortes. Dans le m\u00eame temps, l\u2019augmentation du courant de coupe entra\u00eene \u00e9galement une augmentation du diam\u00e8tre de l\u2019arc, ce qui entra\u00eene \u00e9galement un \u00e9paississement de l\u2019arc et une fente plus large. \u00c9galement en raison de l'\u00e9paississement de la pi\u00e8ce, la section de coupe du plasma est plus rugueuse et la perpendiculaire est pire, m\u00eame en raison de l'augmentation du diam\u00e8tre de l'arc. Rend le plasma incapable de d\u00e9couper des trous de pr\u00e9cision. Et ces probl\u00e8mes peuvent \u00eatre facilement r\u00e9solus pour la d\u00e9coupe laser fibre.<\/p>\n\n\n\n

Pour la d\u00e9coupe plasma traditionnelle, les avantages \u00e9vidents de la d\u00e9coupe laser fibre sont les suivants :<\/p>\n\n\n\n

Le premier est la vitesse de coupe, qui est un indice de production tr\u00e8s important pour les transformateurs, directement li\u00e9 \u00e0 l'efficacit\u00e9 de la production. La d\u00e9coupe laser est beaucoup plus rapide que le plasma en termes de vitesse de d\u00e9coupe par perforation, notamment dans le traitement de plaques moyennes et fines. Particuli\u00e8rement \u00e9vident.<\/p>\n\n\n\n

Le second est l\u2019effet de coupe. De par ses caract\u00e9ristiques, la d\u00e9coupe laser peut r\u00e9pondre \u00e0 des exigences \u00e9lev\u00e9es de rugosit\u00e9 sur la face d'extr\u00e9mit\u00e9 de d\u00e9coupe. Par rapport au d\u00e9coupage au plasma, il pr\u00e9sente les avantages \u00e9vidents d\u2019une haute pr\u00e9cision, d\u2019une extr\u00e9mit\u00e9 lisse et de moins de scories. Dans le m\u00eame temps, les avantages sont des fentes plus \u00e9troites, une conicit\u00e9 inf\u00e9rieure et une verticalit\u00e9 plus \u00e9lev\u00e9e.<\/p>\n\n\n\n

Dans le m\u00eame temps, la d\u00e9coupe laser pr\u00e9sente \u00e9galement plus d'avantages en termes d'environnement de production et de co\u00fbt des consommables.<\/p>\n\n\n\n
