ABSTRACT:
The invention contemplates an elongate extension nozzle attachment for a gas torch whereby flame-spraying of coating-powder material may be applied with precision to the bore of a workpiece. The attachment is detachably securable to conventional torch and/or gas-distributor structure and provides independent flows of (a) carrier gas and powder and (b) combustible-gas mixture to a nozzle which is removably fitted to the discharge end. Provision is made for optional use of one or more flame-shaping discharges of air, inert gas or the like at the discharge end, using a further independent supply system within the attachment.
