Acoustic emission testing (AT)
AT technique is used to evaluate technical condition of a construction in operational settings. The monitoring inspection takes place during regular operations of a construction or equipment. The main advantage of AT is its holistic nature. Appropriate placement of sensors allows the user to detect construction defects over the entire tested object. This method is most commonly used to inspect metal bridges, water towers or pipelines. AT is valuable for detecting defects such as cracks, areas of plastic deformation, corrosion or leaks.
