Abstract
Processo di taglio di un pezzo (2) in materiale ferroso mediante un fascio laser (3), in cui un flusso di ossigeno viene inviato sulla zona di taglio (6) attraverso un condotto (13) a pareti solide che guida il flusso sostanzialmente fino a contatto con una superficie (7) del pezzo (2) stesso; il fascio laser (3) esercita sul pezzo (2) una densità di potenza maggiore di 10 alla 6 KW/cm2; l'ossigeno è inviato sul pezzo (2) con una pressione di impatto sufficiente ad innescare, a tale densità di potenza, reazioni esotermiche di ossidazione del ferro aventi carattere di combustione, e viene alimentato in leggero eccesso rispetto alla proporzione stechiometrica in modo da ottenere tali reazioni in modo completo e da mantenerle in condizioni di equilibrio dinamico.
