Bars & Billets
We offer ultrasonic, Magnetic flux leakage (MFL), Magnetic particle inspection and hybrid bars & billets testing systems. These systems can be categorized into different categories Ultrasonic is for internal, sub surface and surface defects, MFL for surface longitudinal defects and MPI for surface and near surface defects.
Ultrasonics Systems for Bars & Billets
These systems are designed for the inspection of bars, billets and profiles. Systems come with an immersion tank in which the probes are submerged and employ conventional/phased-array methods to provide increased flexibility and the capability to detect internal, subsurface and surface defects.
Salient Features

- Length from 3000 mm to 14000 mm
- Diameter 10 – 200 mm
For big bars (200 – 500 mm)scanning type system is available - Flat bars Sections range: from 15x15mm to 90x110mm
- Material – steel, aluminum etc
- Test speed up to 2 m/s depending on diameter
- Type of UT probes – multi-channel arrays
- High signal-to-noise ratio
- Sensitivity – upto FBH 0.7 mm
- Small untested zones
- Hybrid option for square shape and round bars shape
- Surface inspection with Rayleigh waves option for square shape and round bars shape
- Meets all international standards & specifications including AMS, NADCAP, BOEING, AIRBUS, ASTM, EN, IGC
MFLT Systems for Round Bars
These system is used to detect the flaws on the surface of material which has rough surface such as black steel round bar. Rotating magnetizing yoke and detecting probe are equipped in it, it performs the detection by making tested material pass through inside.
Salient Features
- Round bars in rolled condition
- Diameter 10 – 200. For higher diameters scanning type system available
- Minimum defection size 0.1 mm width & depth, 10mm length
- Test Speed 1000-19000RPM (depends on diameter)
- Contactless rotary transformer as signal transduction of rotating mechanism
- Automatic sizing (optional)
MPI Systems for Bars & Billets
Our Semi-automated magnetic particle inspection (MPI) system consists of material handling equipment with an integral magnetic Inspection station. The MPI unit provides low-voltage, high-amperage current for magnetization and AC for demagnetization.
Salient Features
- Magnetization Options: Alternating Current (AC), Half Wave Direct Current (HWDC), and Full Wave Direct Current (FWDC).
- Magnetization Modes: Circular and Longitudinal, both independently adjustable
- Safety Features: Includes emergency cut off, current assurance indication
- Demagnetization: Automatic AC demagnetization facility with coil only
- Current Range – 2000 Amps to 8000 Amps
- Clamping – Horizontal & Vertical Clamping
- Duty cycle – 2 second “ON” and 8 seconds “Off”
- Amperage Meter – Digital/Analog
- Control System – Thyristor based stepless current control up to 8 steps controller
- User Interface – Features a user friendly HMI with password protection
- Electric supply Requirement – 415 V, 3Phase, +N, 50Hz, 150 Amps
Ultrasonics Immersion Scanner (as per SEP 1927)
To meet the requirements of SEP 1927 (inspection of round and rectangular cross sections with diameters/sizes up to 100 mm), we have designed a 4 axis immersion tank equipped with multiple fixtures, including a turntable, rotating device, and supports for flat specimens, enabling inspection of work pieces with various geometries.
We have also developed a dedicated software for data recording and evaluation in accordance with the SEP 1927
Salient Features
- 4 axis Immersion Scanner with Aluminum Frame
- Motorized X, Y, Z & R
- High quality encoders and DC servo motors
- Real-time A, B and C-Scans
- Data analysis & reporting
- Windows based, multi-tasking software
