Cracks occurring in turbine blade tenons have the possibility of producing severe damage if not detected. Undetected cracks can propagate to a critical size, resulting in loss of shroud, excessive vibration and consequential unit shut down. Advances in the development of ultrasonic techniques have provided Southern California Edison Company (SCE) with an effective method of detecting tenon cracking prior to crack propagation to critical size. The ultrasonic system utilized by SCE incorporates focused array technology and automated scanning techniques and provides many advantages over the conventional manual scanning techniques. This paper addresses the system utilized by the company and the results of inspections since the introduction of the equipment to the power generation industry.
