Seebeck discovered that when two dissimilar metals are connected (“junctioned”) together, a minute electric potential will be generated. This phenomenon, known as the Seebeck Effect, is the basis of how a thermocouple functions.

Aerospace Material Specification 2750 (AMS 2750) is the main pyrometry specification that provides the requirements for the calibration and testing of thermal-processing equipment.

Aerospace special-process providers seeking Nadcap accreditation agree that the process has elevated the level of compliance from procedural accuracy, training, documentation, equipment functionality and process control.
