Non-destructive ultrasonic testing of sheet steel – Quality assurance at UnionStahl

Ultrasonic testing of sheet metal is a proven non-destructive testing method for quality assurance and for identifying inhomogeneities inside heavy plates. This method makes it possible to detect defects such as blowholes, inclusions or binding defects, thereby ensuring the safety and reliability of the end products.

Why is ultrasonic testing of sheet metal important?

Industrial sectors such as mechanical engineering, offshore wind power and steel construction place the highest demands on the quality of sheet metal. Material defects can not only cause economic losses, but also have safety-critical consequences. Non-destructive material testing ensures that the sheet metal supplied complies with national, European and international testing standards.

Methodology of ultrasonic testing

Manual for flexibility and precision

UnionStahl performs ultrasonic testing manually using high-precision ultrasonic testing devices. This approach enables flexible and individual adaptation to specific customer requirements.

How does ultrasonic testing work?

Ultrasonic testing is based on the transmission of high-frequency sound waves into the material. These waves are reflected at interfaces and make it possible to precisely analyze the inner structure of the sheet metal. Defects such as cavities or inclusions are made visible by altered reflections. The inspector can thus assess the material quality in real time and document any irregularities.

Ultrasonic testing according to international standards

Thanks to these standardized test methods, we ensure that our customers receive sheet metal that meets the highest technical requirements:

• DIN EN 10160 –
• ASTM A578/A578M –
• ASTM A435/435M

Areas of application for ultrasonic testing

Ultrasonic testing is used in various industries, including

• Steel construction and bridge construction – ensuring load-bearing capacity and avoiding material failure
• Mechanical engineering – Testing components for freedom from defects to ensure long-term functionality
