Automated Ultrasonics

Hydrogen Induced Cracking

 

 

The images show "C Scan" and "B Scan" plots of a sample containing Wet Hydrogen damage.

The techniques used to produce this form of data require the production of a consolidated data set.

The data from transducers using multiple modes of ultrasound are used in a single array.

The data from the multiple transducers is collected simultaneously, consolidated and shown as a single plot.

 

Note, at a single location the sound is transmitted through the complete section of the sample.
