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.
A vacuum furnace control system is a major capital investment that affects every aspect of your thermal processing capabilities, so choosing the right system can feel like a daunting task. It doesn’t have to. Simply follow these guidelines to ensure you get a vacuum furnace control system that meets your needs and delivers exacting and reliable performance.
Supervisory control and data acquisition (SCADA) is a system of hardware and software that allows manufacturers to precisely control and monitor a variety of industrial processes. Implementing SCADA can seem daunting, but these SCADA control panel systems offer a lot of compelling advantages.
Here are a few reasons to stop thinking about SCADA and move forward with implementation.
The National Aerospace and Defense Contractors Accreditation Program (Nadcap) has clear and stringent guidelines for accreditation. One area that often causes problems is the incorrect handling, formatting and storage of data. The good news is that Nadcap offers a clear list of requirements, and by installing the right equipment and following some basic steps, meeting these data demands is simple.
Meeting Nadcap certification requirements and avoiding non-conformances in audits is a complex and challenging process, but it doesn’t need to be intimidating.
Very few plant managers think about their thermal process control systems unless there are obvious signs of problems or fallout from a failed audit.
