TOPH ultrasonic testing
Time Of Flight Diffraction is a supplementary ultrasonic testing method, which provides high scanning speed and records results. It is usually used to test repetitive elements, such as welds of similar sizes. TOFH method is used primarily to test welded connections. The process is digitally recorded, enabling subsequent analysis and result verification. This method results in a high defect detection rate and a low number of false indications, allows the user to accurately measure the geometry of defects in three dimensions and takes less time than conventional methods.
