In industries like aerospace, amusements, commercial manufacturing, and construction, there’s no room for compromise. Rigorous testing ensures the safety, integrity, and compliance of each component, helping prevent minor defects from turning into costly failures.
Two of the most common testing options are Non-Destructive Testing (NDT) and metallurgical testing. While both help protect people, equipment, and outcomes, they answer different questions.
American Testing Services specializes in non-destructive and metallurgical testing at our state-of-the-art facility in Dayton, Ohio. We offer full-spectrum solutions so you can arm yourself with the knowledge you need to know, before you need to know it.
So, what’s the difference between NDT and metallurgy? Let’s take a closer look:
What is Non-Destructive Testing (NDT)?
Non-destructive testing is a wide group of inspection methods used toevaluate a material, component, or structure in its current state without physically or chemically altering it.
Non-destructive testing connects you with clues that could impact the performance or safety of a component, including flaws such as:
- Cracks
- Voids or porosity
- Welding defects
- Corrosion or thinning of materials
- Other defects not visible to the naked eye
After passing NDT inspection, a part or component can stay in service or move forward in the production process.
Common NDT methods
American Testing Services offers a broad range of NDT services to meet the requirements of today’s aerospace, manufacturing, and construction industries, including:
- Visual Testing
- Ultrasonic Inspection
- Radiographic / Computerized Radiography
- Magnetic Particle Testing
- Liquid Penetrant Testing
- Eddy Current Testing
In addition to these core NDT methods, American Testing Services also offers Wire Rope inspection, Bolt Torquing, and Certified Weld Inspector Services to support specific applications.
What is Metallurgy?
Metallurgical testing focuses on the material itself — its microstructure, chemical, and mechanical properties. Unlike non-destructive testing, metallurgy may involve altering a sample of the component to uncover results. It helps predict how a material will perform in the future, so you can proactively prevent failure and strengthen results.
Metallurgical analysis can be employed as part of a quality assurance program. It also has many applications in the research and development phase of manufacturing.
Metallurgical testing is commonly used when:
- Selecting materials or suppliers for a demanding application
- Routine testing and quality assurance
- Gathering data on a material’s strength, ductility, and performance
- Determining the root cause of a product or material failure so it can be prevented moving forward
Metallurgical Testing Capabilities
American Testing Services offers metallurgical testing as a stand-alone service or as a complement to any of our non-destructive testing services. Our metallurgical capabilities include:
- Chemical analysis
- Mechanical testing (tensile, hardness, impact, etc.)
- Metallography
- Corrosion testing
- Weld qualification testing
- Failure analysis and root cause investigation
Why Many Projects Need Both
For many applications, NDT and metallurgy work best together.
Metallurgy “breaks” it so you know how, why, and where it’s possible to fail. Non-destructive testing shows you what you need to see without breaking it. Together, these testing techniques can give you complete confidence in your materials and components for a given application.
