Ultrasonic Phased Array:
MAC can offer Phased Array technology to allow simple testing of both round corner square billets and large round billets. MAC has a unique Phased Array cassette system that allows quick change between the two major geometries (round or square). The transducer assemblies follow the product surface and allow the testing to be optimized relative to the bar center.
Eddy Current/Ultrasonic Multi-Test:
Custom Eddy Current system tests billets using rotary probes to inspect flat surfaces and tangent coils for the corners
MAC can supply a combined Eddy Current and Ultrasonic system for inspecting hot rolled square and round billets up to 9” (228.6mm) in diameter.
- The 8-channel eddy current test uses both sector and rotary test probes to spot defects on the flat surfaces and corners. Square or round corner billets can be tested.
- The UT system can be Phased Array or conventional array type testing. The UT method detects internal defects and makes it possible to volumetrically inspect large bar product.
- These tests meet MIL STD 2154 standards.
MultiMac® Eddy Current Billet System
Eddy Current tangent coils test billet corners
- Detects longitudinal defects in the flat surfaces, detects transverse and longitudinal flaws on the corners.
- MultiMac® electronics have eight test channels.
- Test frequencies can be selected from 1 kHz to 5 MHz with a flaw bandwidth
up to 5 kHz.
- Set-up can be accomplished in less than 10 minutes and a size change only requires an adjustment of the headplate probes.
- The MultiMac® electronics used in the billet test system have a full Windows® based user interface, making it easy and intuitive to operate.
Echomac® FD6 Ultrasonic Billet Inspection System
- Echomac®FD6 UT test electronics with 48 channels are expandable to 64 channels.
- Mechanical operation consists of four transducer test heads, each with three surface ride shoes containing three or four transducers, and one bubbler for coupling purposes.
- A tracking and marking system is available to identify indications.
- Features an offline calibration station and an integrated water circulating and cooling system.
