A vital method for detecting Internal Flaws in Materials

Ultrasonic Testing (UT) is a Nondestructive testing method to detect flaws that are internal in nature. Though it can detect, surface and subsurface flaws using angle beam, due to dead zone, UT is recommended for finding internal flaws such as cracks, shrinkage, blow holes, lack of fusion, slag inclusions etc.,. The method is suitable for testing castings, forgings, plates and welds. Metals and nonmetals such as ceramics, plastics, composites are also candidates for this method. Virtually any material that conducts ultrasonic sound can be tested.

UT testing method uses high frequency sound waves that are above 20KHz. For mechanical applications, materials are usually in the range of
500kHz to 10MHz. For critical aircraft and space applications, frequencies starting from 10MHz up to 25MHz are commonly used.

UT of Castings, Forgings, Plates & Welds

Ultrasonic inspection is effectively detects anomalies in Ingots, castings, forgings, rolled plates and welds. UT can also be suitable for testing raw materials, in process and finished materials. It is the preferred method for detecting internal flaws during in-service inspection of plants. That is to say, this can detect fatigue cracks, measure wall thickness and estimate quantum of corrosion damages on shafts, gears and pipelines.

In addition, digital Ultrasonic thickness measurement gives wall thickness of boiler pipes, tubes, tanks, pressure vessels and chimneys. Though thickness can also measured using flaw detectors, but accuracy cannot match to the digital thickness gauges. Therefore, digital ultrasonic thickness gauges are preferred and can measure up to an accuracy of 0.001mm under certain conditions.

Ultrasonic method cannot detect cracks and other defects which are parallel to the beam direction. Therefore, it cannot detect cracks originated from surface. For such cracks, surface methods such as Dye penetrant, magnetic particle or eddy current are recommended.
