Market Size and Growth The global NDI equipment market has witnessed significant growth in recent years. The market was valued at USD XX billion in 2023 and is projected to reach USD XX billion by 2032, growing at a CAGR of approximately X.X% over the forecast period (2024–2032). Growth is being driven by stricter government regulations, aging infrastructure, and the need for high-precision inspection in advanced manufacturing processes.
Key Types of NDI Equipment NDI encompasses a wide variety of inspection technologies, including:
Ultrasonic Testing (UT): Uses high-frequency sound waves to detect flaws in metals and composites.
Radiographic Testing (RT): Employs X-rays or gamma rays to view internal structures.
Magnetic Particle Testing (MT): Detects surface and slightly subsurface discontinuities in ferromagnetic materials.
Eddy Current Testing (ET): Uses electromagnetic induction to detect surface cracks and material thickness.
Visual Testing (VT): Involves direct visual examination or use of remote visual inspection tools like drones or robotic cameras.
Thermography: Uses infrared cameras to detect heat differences which can indicate subsurface flaws or energy inefficiencies.
