The metals industry is a major user of automated ultrasonic systems and USL has been a principal supplier since 1990. The current USL multi-channel ultrasonic instrumentation is ideally suited to these applications, in combination with both off-line immersion and in-line irrigated mechanical systems.
Products inspected using USL systems include:
Some products, such as steel and titanium plate require multiple probes using the same basic settings for rapid coverage and maximum throughput. Others, such as rail wheels and axle forgings, need probes set at different angles for detection of longitudinal, axial and circumferential defects. The USL multiplexed electronics can switch all settings at full pulse repetition frequency rates up to 20kHz to suit both types of test. Configurations from 2 to 32 channels are available. Software is available for different applications, such as:
Customers include Alcoa Europe (Flat Rolled Products), Timet UK, Timken Steel, Voest Alpine Steel, Tata Steel, Firth Rixson Forgings, Alro and Southwest Aluminium Company.
