Matrix Phased Array Testing Technology
Matrix phased array testing uses a matrix of transducer elements to steer and focus beams electronically. This enables precise detection of flat flaws and cracks in complex parts.
Physicochemical Mechanism of Action
Matrix phased array testing uses a 2D array of transducer elements that can be electronically controlled. These elements send and receive ultrasound waves, which are then steered in different directions and angles. By combining the signals, a precise image of the internal condition of a material can be produced.
Metallurgical Relevance & Welding Risks
This technique is especially useful for inspecting complex components and weld areas because it allows a detailed analysis. It can detect flaws and cracks in various directions, which often conventional methods can't achieve. A key advantage is the ability to precisely locate and size indications, which is especially important for quality assurance of weld areas.
Workshop Practice & Procedures
To use matrix phased array testing effectively, the following steps are important:
1. Equipment: Use a high-quality phased array system with a suitable matrix of transducer elements.
2. Preparation of the test area: Make sure the area to be tested is clean and free of interfering factors.
3. Adjust settings: Adjust the system settings (like frequency, wave direction) to the specific test area and material.
4. Perform the test: Move the system over the test area and capture the ultrasonic data.
5. Evaluate results: Analyze the captured data with suitable software to locate and size flaws and cracks.
