Pyrometry procedures that comply with AMS2750E and/or Nadcap requirements can be complex and challenging to meet. I often perform gap analyses on heat-treat processes and uncover issues with procedures and work instructions that, if not remedied, will ensure failure when it comes to meeting Nadcap or AMS2750E requirements.
As a specialist in process controls, my company offers comprehensive temperature uniformity surveys. Through years of training operators and helping companies work on temperature uniformity survey procedures, I have found one of the sticking points in meeting compliance standards involves thermocouples.
Compliance verification is a foundation for a number of industry specifications, such as Nadcap and AMS2750E. Many people focus on following the right procedures and overlook the need to clearly account for all requirements in their internal procedures. When meeting industry standards, it’s imperative to not only capture all of the requirements but state them clearly and unambiguously within your procedures.
If you work in thermal processing in any way, it’s likely that you’ve heard of the National Aerospace and Defense Contractors Accreditation Program (Nadcap). After more than 20 years in aerospace as a metallurgical engineer, much of which in consulting, I’ve heard a lot of opinions about the Nadcap certification process. It’s a rigorous process, so it’s not surprising that it can cause frustration, but I strongly believe meeting Nadcap requirements are the gold standard in process control for many good reasons.
Any business handling heat treating for aerospace customers is likely to face Nadcap audits. Manufacturers like Boeing and Airbus require Nadcap accreditation, so the vast supply chain of subcontractors handling aerospace products must meet and maintain Nadcap requirements.
The quality and safety of heat treatment products are imperative. Because of this, the National Aerospace and Defense Contractors Accreditation Program (Nadcap) has clear and stringent guidelines for accreditation, which can often be challenging to attain. In this blog, I outline the step-by-step process for suppliers to gain Nadcap approval.
Ensuring that a furnace can perform repeatable and accurate cycles is a cornerstone of AMS2750E pyrometry specifications as well as Nadcap and CQI-9 standards. The best way to measure and test any furnace is through a temperature uniformity survey (TUS).
When it comes to pyrometry and thermal processing, details are critical. Adhering to the exacting standards of AMS2750E demands that each step of heat treating meets specific requirements for sensors, instrumentation, equipment, tests and other details.
