Sensitivity Response of Total Focusing Method (TFM) for Weld Inspection

Total Focusing Method (TFM) is an ultrasonic-based technique enhanced with the post-processing algorithm.

P009 TFM

Although TFM is greatly promoted, there are some concerns, especially for weld inspection. This article evaluates the amplitude variation towards specific flaw orientation and compares it with other techniques, such as phased array ultrasonic testing (PAUT) and radiographic testing (RT).
