Method of producing a plug-type heat flux gauge

摘要

A method of making a plug-type heat flux gauge in a material specimen in which a thermoplug is integrally formed. The thermoplug and concentric annulus are formed in the material specimen by electrical discharge machining and trepanning procedures. The thermoplug is surrounded by a concentric annulus through which thermocouple wires are routed. The end of each thermocouple wire is welded to the thermoplug, with each thermocouple wire welded at a different location along the length of the thermoplug.
