INNRETNING FOR TERMISK SPRTING AV PŸLEGGSSVEISEMATERIALE R.

摘要

A device for the thermal spray application of welding materials comprises a jet focussing nozzle having an axis and defining an elongated, axially extending jet focussing channel having a feed-in end, and a burner nozzle in the pinch nozzle for directing a flame into the feed-in end. The jet focussing nozzle is divided into two connected parts along a plane extending transversely to the jet focussing nozzle axis in the area of the feed-in end and dividing the jet focussing nozzle into a front part and a rear part receiving the burner nozzle, and the front nozzle part is adjustable with respect to the rear part between an operating position wherein the nozzle parts have contacting end faces in this plane and the jet focussing channel extends continuously through the nozzle parts, and an ignition position wherein the front part clears the burner nozzle for access thereto.
