Ultrasonic NDT for Steel in Bangladesh

Key Features of Ultrasonic NDT for Steel

• Internal Defect Detection: Identifies internal cracks, inclusions, laminations, and discontinuities.

• Non-Destructive Inspection: Evaluates steel components without damaging the material.

• Thickness Measurement: Measures steel thickness and monitors corrosion or material loss.

• Weld Inspection: Detects and evaluates defects in welded steel joints.

• Portable Testing: Supports on-site inspection of steel structures and industrial components.

• Accurate Evaluation: Provides test data to support material quality assessment and inspection decisions.

• Digital Reporting: Compatible models support data storage, waveform analysis, and inspection reporting.

Types of Ultrasonic Testing for Steel

Depending on the inspection requirements, different ultrasonic testing techniques can be used:

• Conventional Ultrasonic Testing (UT): Detects internal discontinuities in steel components using straight-beam and angle-beam probes.

• Ultrasonic Thickness Measurement: Measures steel thickness and identifies material loss caused by corrosion or erosion.

• Weld Ultrasonic Testing: Examines welded joints for internal defects, including cracks, lack of fusion, and incomplete penetration.

• Phased Array Ultrasonic Testing (PAUT): Uses multiple ultrasonic elements to generate and steer sound beams for advanced inspection and imaging.

• Time of Flight Diffraction (TOFD): Uses diffracted ultrasonic signals to detect and size weld defects.
