超声波探伤仪
超声波探伤仪 (UT) 利用 高频声波 to penetrate materials and detect internal flaws. They are commonly used for inspecting metals, composites, plastics, and welds, offering fast and precise defect detection. These devices measure the time it takes for sound waves to reflect from discontinuities within a material, making them ideal for identifying hidden cracks, voids, or inclusions.

探伤仪常见问题解答
1。 什么是探伤仪？
A flaw detector is a non-destructive testing (NDT) device used to detect surface and internal defects in materials or components. These defects could include cracks, voids, porosity, or inclusions, which can compromise the integrity of the material.
2。 超声波探伤仪如何工作？
An ultrasonic flaw detector sends high-frequency sound waves into a material. The waves reflect off internal flaws or surfaces, and the device interprets these echoes to detect defects such as cracks or voids, even if they are deep within the material.
3。 磁轭探伤机有哪些优点？
Magnetic yoke flaw detectors are easy to use, lightweight, and affordable. They are ideal for detecting surface and shallow subsurface defects in ferromagnetic materials such as steel. This method is commonly used for inspecting welds, pipelines, and railway tracks.
