A. Product Overview

The Metrix Plus UTFD 80 Ultrasonic Flaw Detector is an advanced digital NDT instrument used for identifying internal defects and discontinuities in materials.

Unlike destructive testing methods where a component may need to be cut or damaged for inspection, ultrasonic flaw detection allows technicians to examine the internal condition of a component while keeping it intact.

The UTFD 80 is designed for professional ultrasonic testing applications and can help identify defects including:

• Internal cracks
• Voids
• Porosity
• Pits
• Weld discontinuities
• Internal material abnormalities
• Imperfections within components

Important capabilities include:

• Frequency range: 0.5 to 20 MHz
• Measuring range: up to 10 m
• A scan and B scan capability
• Storage for up to 1000 A scan frames
• Gain up to 120 dB
• Material velocity range from approximately 1000 to 15000 m/s
• Automatic calibration
• Automatic gain functions
• DAC functionality
• TCG functionality
• AVG functionality
• AWS D1.1 evaluation support
• DGS curves
• Automatic flaw location measurement
• Straight beam and angle beam probe support
• Backlit color display
• Adjustable gain, gate and rectifier settings
• PC interface
• Solid metal housing
• IP65 protection
• Rechargeable built in battery
• Portable construction for field inspection

These capabilities make the UTFD 80 suitable for detailed ultrasonic testing, weld inspection, material integrity testing and industrial NDT inspection.

B. Working Principle

The Metrix Plus UTFD 80 works using ultrasonic flaw detection technology.

An ultrasonic probe sends high frequency sound waves into the material being inspected. These ultrasonic waves travel through the material.

When the sound wave encounters a boundary or an internal discontinuity such as a crack, void or porosity, part of the ultrasonic energy is reflected back toward the probe.

The flaw detector receives these returning echoes and displays them as ultrasonic waveforms.

The technician analyses factors such as:

• Echo position
• Echo amplitude
• Sound path
• Depth
• Distance
• Gain
• Material velocity

to determine whether an internal discontinuity is present and where it is located.

A Scan

A scan displays ultrasonic signals as waveform peaks. The position and amplitude of the echoes help the operator evaluate the depth and relative response of a flaw.

B Scan

B scan provides a sectional representation created from multiple ultrasonic measurements, helping the technician understand the position and distribution of internal discontinuities.

Using these ultrasonic responses, an experienced NDT technician can evaluate the internal condition of the component without cutting or damaging it.

C. Why Is the Metrix Plus UTFD 80 Used?

The UTFD 80 is primarily used when engineers need to inspect the internal condition of a material without damaging the component.

It can be particularly useful for detecting hidden defects that may not be visible during normal visual inspection.

Common applications include:

Weld Inspection

Used for checking welded joints for internal cracks, porosity, voids and other weld discontinuities.

Metal Inspection

Used for inspecting metal components for internal defects that could affect structural integrity.

Fabrication Quality Control

Fabricators can use ultrasonic testing to verify critical components before installation or delivery.

Pipeline Inspection

Ultrasonic flaw detection can be used as part of inspection procedures for pipes and pipeline components.

Storage Tank Inspection

Useful for checking components used in storage tanks and industrial vessels.

Oil and Gas Industry

Suitable for NDT inspection requirements involving pipelines, fabricated structures and other industrial components.

Aerospace Inspection

Ultrasonic flaw detection is commonly used where internal material integrity is important.

Preventive Maintenance

Maintenance departments can inspect critical components for developing defects before they result in unexpected failure.

Quality Assurance

Manufacturers and inspection departments can incorporate ultrasonic flaw detection into quality control procedures.
