Abstract
Method and plant for cutting or welding by a laser beam with dual-flow and double-focus cutting head. The plant includes a laser generator to generate at least one main laser beam ( ), a first optical element ( ) enabling the main laser beam ( ) to be divided into at least two subsidiary laser beams ( ), a first outlet nozzle ( ) through which one ( ) of the subsidiary laser beams passes, and a second outlet nozzle ( ) through which the other ( ) of the subsidiary laser beams passes, the first and second outlet nozzles ( ) being approximately coaxial one with the other. In this way, it is possible to focus the central beam ( ) onto a focusing point (PF) by a first focusing element ( ), such as a lens, and the other beam ( ) onto an annular focusing zone (ZAF).
