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.

This coordinated Nadcap system results in a standardized approach to quality assurance and a reduction in redundant auditing throughout the aerospace industry.

Just like individuals, each business will have its unique challenges and some commonalities as well. For heat treaters, the need to maintain customer approvals, industry accreditations, equipment calibration and furnace efficiency are vital to their current and future ability to provide heat-treatment services. Yet these are not easy to achieve in optimal conditions, and today’s world is indisputably suboptimal. 

Questions about AMS 2750 are common for readers of this journal. We review the impact of this important pyrometry specification to help you deal with the complexities and unknowns in the high-temperature environment of sintering.

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.
