General NDT

Nondestructive testing (NDT) technology serves as the "Guardian of Safety" and "Judge of Quality" in modern industry, particularly in high-risk sectors such as aerospace, rail transportation, energy and power, and pressure vessels. Through a series of "keen-eyed" technical means, it ensures that industrial facilities remain in a safe and controllable state throughout their entire lifecycle, from "birth" (manufacturing) to "retirement" (scrapping).

It has extensive industrial applications, including but not limited to aerospace, nuclear industry, weapons manufacturing, mechanical engineering, shipbuilding, petrochemicals, railways and high-speed trains, automotive manufacturing, boilers and pressure vessels, special equipment, and customs inspection. Currently, the most commonly used nondestructive testing methods primarily include five types: Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), Penetrant Testing (PT), and Eddy Current Testing (ET).

Technological Development Trends:

Digitalization and Automation: Testing equipment is becoming digitalized, allowing data to be directly stored, transmitted, and analyzed. Robots and scanners are widely used in complex environments to enhance inspection efficiency and consistency.

Intelligent and AI-Based Interpretation: Artificial intelligence (AI) and machine learning algorithms are utilized to automatically identify and evaluate defect images (e.g., RT and UT images), reducing human error and improving interpretation accuracy and efficiency.

Multi-Technology Integration: Multiple NDT methods are integrated into a single system, leveraging their complementary advantages to achieve comprehensive and holistic evaluation of workpieces.

In-Service and Online Monitoring: Advances in sensor technology and the Internet of Things (IoT) enable the long-term, real-time condition monitoring of critical equipment and structures.
