The Solution

In order to test plates for hydrogen-induced cracks, samples are cut out of plates and exposed to a sour medium containing hydrogen sulfide, then tested with ultrasound to establish characteristic variables with which resistance to hydrogen-induced cracking is measured. ROSEN designed, developed and manufactured an automated ultrasound testing system with a 3-axis gantry scanner tailored to the customer’s quality control process and environment. An immersion basin allows samples on the sample carrier to be automatically tested with ultrasound. In preparation for the test, the system operator manually places the prepared samples on the dry sample carrier, and enters the layout plan and test parameters into the system software. An alternative method is to download the layout and the test parameters from the main production planning system into the system software. Following that, the test basin is raised and the samples immersed in the water bath are automatically scanned. The ROSEN evaluation software automatically determines the characteristic variables in accordance with the applicable standards and quality criteria. When the test procedure is complete, the test basin is lowered and the samples are dried with an automatic blower.
