Ultrasonic Wall Thickness Measurement
Ultrasound is used to measure the remaining wall thickness of components. It measures the time it takes for the ultrasonic signal to travel between the front and back wall.
Physical-Chemical Mechanism of Action
Ultrasound is a high-frequency sound wave that is easily reflected in metals. The time it takes for the ultrasonic signal to travel between the front and back walls depends on the material thickness.
Metallurgical Relevance & Welding Risks
Ultrasonic wall thickness measurement is critical for the safety and functionality of components. A too-thin remaining wall can lead to cracks or failure. Incorrect measurements can lead to inaccurate results, posing risks in construction and mechanical engineering.
Workshop Practice & Action Instructions
Use a high-resolution ultrasonic device. Ensure the couplant fully covers the surface. Measure the transit time between the front and back walls and calculate the thickness using the known sound velocity of the material.
