Beveling tip

摘要

What is disclosed is a tip for a cutting torch for beveling steels at angles greater than 45 DEG with respect to the perpendicular and characterized by an inner piece having a cutting oxygen aperture drilled through the center and fluted around its periphery and conformably fitting within an outer piece, the outer piece extending beyond the inner piece and with an exit diameter smaller than the chamber downstream of the inner piece and with critical relationships between the diameter of the exit aperture, the cutting oxygen aperture and diamensions of the chamber defined downstream of the inner piece and upstream of the exit aperture of the outer piece such that a bulbous flame is obtained at the tip of the outer piece that will cut smoothly at beveled angles of from 45 DEG to 90 DEG with respect to the perpendicular.
