gratis internet dejting Improvement of ultrasound backing on NDE probes

nätdejting seriös OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Background
Probes for mechanized NDE purposes are typically placed on the surface to be inspected using a manipulator system. The manipulator is remotely controlled and usually operates in hazardous conditions (reactor vessels etc.). The probe is manipulated in a pattern over the surface and data (ultrasonic or eddy-current) is collected and analyzed.

Many of our products utilize TOFD (time-of-flight diffraction) ultrasonic (US) probes for non-destructive testing of nuclear reactors. To achieve a good signal the ultrasonic probe must be well damped. Today multiple manufacturing efforts are required to obtain a high-quality probe.

The aim of this project is to improve the manufacturing process of backing for ultrasonic probes to achieve a well-known outcome. The current method/process result in backing with very varying bandwidths and is unreliable. Investigate which factors are the most important and figure out a method producing backing material of high quality and reliability, in order to decrease the overall manufacturing time for ultrasonic NDE probes.
