Automated Ultrasonic Technique (AUT):
1. B and C-Scan Corrosion Mapping – Unlike standard ultrasonic thickness measurements, where typically a single thickness reading is taken, automated ultrasonic C-scan techniques can provide thousands of equivalent ultrasonic readings and cover very large areas in a fraction of the time it would take to gather manual ultrasonic data. Additionally, a C-scan map can provide a valuable global look at corrosion damage and assist in the identification of the lowest or minimum thickness location.
2. B and C-Scan Discontinuity Evaluation – A common application of this method is the detection of cracking and other service related damage. The most common damage mechanisms detectable with AUT are hydrogen induced cracking (HIC), hydrogen blistering and stepwise cracking, as well as stress corrosion cracking.
3. B and C- Scan Weld inspection/evaluation – A method of detecting and evaluating defects in the weld volume and also root defects. The procedure can be applied on new equipment, during the fabrication process, and on “in-service” equipment to detect flaws characteristic to each type of process.
We have the tools, expertise, and knowledge to set up effective automated ultrasonic testing on your large equipment and piping. We utilize this technique most commonly for performing shearwave on the welds of your large diameter bullets and for gathering corrosion mapping data for your larger pressure equipment. On-line inspection techniques like this can save thousands in outages and downtime.
