Ultrasonic Testing of Brazed Joints Ultrasonic testing (UT) is commonly used to inspect the quality of brazed joints. The process of evaluating brazing quality is generally simple: using a focused transducer, ultrasonic waves are transmitted at 0° through the part along the radius of the shaft and … [Read more...]
Dynamic range of advanced ultrasonic systems Aerospace composite materials and structures take many forms, from thin plates to complex 3D shapes. One of the challenges of inspecting the more complex structures while using ultrasonic systems is to maintain a good SNR in all portions of the part. … [Read more...]
The introduction of automated ultrasonic testing has benefited the nondestructive testing (NDT) field in terms of increased inspection speed, imaging capabilities and repeatability. Ultrasonic immersion tanks and squirter systems are well suited for flaw detection of large aerospace parts. Complex … [Read more...]
Turbine blades used in aircraft engines and power generation systems are designed with internal air cooling channels which allow the blades to operate under extremely high temperatures. Thickness variation at the cooling channels which is caused by bad machining repair or surface wear during … [Read more...]
Cast aluminum molding plates or blocks are frequently used for large molds requiring extensive machining applications. They are characterized by excellent dimensional accuracy, stability and strength. Such casting technology uses direct chill (DC) vertical casting process to form precisely the … [Read more...]
