Abstract
An improved nozzle is provided for a metal spraying torch, said nozzle comprising a hollow cylindrical body having a substantially conically shaped nose terminating into a tip and a plurality of gas-conducting orifices communicating with the hollow of said nozzle and passing substantially axially through the nose of said nozzle, for example, coaxially parallel or conically disposed relative to the axis of the nozzle, and emerging from the conical surface thereof short of the tip. The orifices are radially disposed about the axis of said nozzle with the terminal portions thereof lying in a circle when observed from the tip end. An advantage of the nozzle is that it provides a quieter flame and also avoids flashback when the tip thereof makes contact with a workpiece.
