Abstract

A laser processing apparatus (10; 110; 210), in particular for cutting and welding, including a focusing head (12; 112; 206) for focusing the beam on the work area (13, 13a; 113; 207) of the workpiece (15; 118; 209), and a nozzle (17) with a conduit (21; 120; 220) for directing a jet (18; 122; 213) of assist gas at a supersonic speed at least close to the work area (13, 13a; 113; 207). The work area (13, 13a; 113) is preferably covered by the walls of the conduit (21; 120) located downstream from the nozzle (33a, 33b, 33c; 132). To ensure optimum working conditions of the apparatus, the nozzle (217) is preferably supported for rotation about the focusing head (206), and is so controlled that, at least at the work area (207), the conduit is maintained tangent to the work path (T).
