Description

ABSTRACT:
The nozzle includes an axially extending discharge passage of circular cross-section and having a convergent entrance portion, a constricted throat which is axially and circumferentially convex, and an enlarged diameter exit portion which is concave in the axial direction as well as in the circumferential direction. The annular wall which defines the axially concave exit portion terminates perpendicular to the extreme end of the nozzle. By virtue of the shape of the passage, the plasma is discharged from the nozzle at supersonic velocity and substantially in the form of a collimated stream so as to effect faster and squarer cutting of a metal workpiece.
