Ultrasonic Testing (UT)

Lingtec Ultrasonic Testing UT – Best Ultrasonic Inspection Provider in Malaysia

Welcome to Lingtec Ultrasonic Test Industry, the best provider site of ultrasonic testing services in Malaysia. If you’re not familiar with ultrasonic testing techniques (UT), don’t worry – we’re here to give you an overview and guide you through it.

What is Ultrasonic Test (UT)?

Ultrasonic testing, also known as UT, is a non-destructive testing (NDT) method used to detect and evaluate flaws or inconsistencies in materials or structures of products. It works by sending high-frequency sound waves into the part and analyzing the waves that bounce back. Ultrasonic inspection system is widely used in various industries, including manufacturing, construction, and aerospace, to ensure the integrity and safety of current critical components.

When performing ultrasonic testing solutions, a technician uses a handheld device called an ultrasonic transducer. This transducer emits ultrasonic waves into the object being tested. The waves travel through the material until they encounter a boundary or flaw. At this point, some of the waves are reflected back to the transducer, while others continue to scan through the object to test the rest of the part.

The reflected waves are picked up by the transducer and converted into electrical signals. These signals are then processed by a computer or specialized equipment, which analyzes the amplitude, frequency, and time of flight of the waves. Ultrasound testing is often performed on steel, other metals, alloys, or even piping tube materials, though it can also be used on concrete, wood, and composites, albeit with less resolution. It is used in many industries including steel and aluminum construction, metallurgy, manufacturing, aerospace, automotive, and other transportation sectors.

Features of Ultrasonic Testing (UT)

Accurate and Reliable Results

One of the key features of UT engineering techniques is its ability to provide accurate and reliable results. The advanced technology used in UT allows for precise flaw detection and characterization, ensuring that even the smallest defects of products are detected.

Non-Destructive Testing Method

UT is a non-destructive testing (NDT) method, meaning it doesn’t require the material to be damaged or destroyed in order to perform the inspection. This makes it an ideal choice for testing critical components without compromising their integrity.

Fast and Efficient Inspection

With UT management, inspections can be performed quickly and efficiently. The high-speed data acquisition capabilities of UT equipment allow for rapid scanning and analysis, reducing inspection time and increasing productivity.

Wide Range of Applications

UT can be applied to a wide range of materials without penetrant, including metals, plastics, composites, and ceramics. It can be used to detect various flaw types, such as cracks, voids, welds, and delaminations, making it a versatile testing method for different development industries.

How to Choose The Correct Equipment for Ultrasonic Testing (UT)?

Application Requirements

When choosing the correct equipment for UT, it’s important to research and consider the specific requirements of your application. Different materials and flaw types may require different frequencies, probe types, and features. Consulting with our experienced professionals can help you determine the most suitable equipment for your needs.

Budget Constraints

Another factor to consider is your budget. UT equipment comes in a wide range of prices, depending on their capabilities and features. It’s essential to find a balance between your budget and the quality of equipment you require. Our experts can work with you to find the most cost-effective solution.


Using UT equipment should be intuitive and user-friendly. Look for equipment with user-friendly interfaces and ergonomic designs that facilitate ease of use and minimize operator fatigue. Our range of UT equipment is designed with user experience in mind, ensuring efficient and comfortable inspections.

Technical Support and Training

Technical support and training are crucial when it comes to using UT equipment effectively. Ensure that the equipment supplier provides comprehensive training and support to maximize the performance and capabilities of the equipment. At Lingtec, we not only provide top-quality equipment but also offer training and ongoing support to our customers.

Main Components of Ultrasonic Testing (UT)

The main components of an ultrasonic testing system include the ultrasonic thickness gauge (UTTG), ultrasonic flaw detector (UTFD), phased array ultrasonic testing (PAUT), NDT industrial scanner, transducer, and probe, and ultrasonic couplant. Each component plays a vital role in the overall UT inspection process.

Ultrasonic Thickness Gauge (UTTG)

The ultrasonic thickness gauge, also known as UTTG, is a handheld device used to measure the thickness of materials. It utilizes ultrasonic waves to determine the thickness by measuring the time it takes for the sound wave to travel through the material and back. UTTG is commonly used in applications where material thickness is critical, such as corrosion monitoring and ensuring structural integrity.

Ultrasonic Flaw Detector (UTFD)

The ultrasonic flaw detector, also referred to as UTFD, is a versatile device used to detect and evaluate flaws in materials. It provides real-time images and data of the inspected material, allowing for accurate flaw detection, sizing, and characterization. UTFD is widely used in industries such as aerospace, manufacturing, and construction, where the quality and safety of critical components are of utmost importance.

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing, or PAUT, is an advanced technique that uses multiple ultrasonic beams to inspect materials. By controlling the timing, frequency, and amplitude of the ultrasonic waves, PAUT allows for precise control over the inspection process. It offers faster scanning and improved defect detection compared to traditional UT methods, making it a preferred choice for complex inspections.

NDT Industrial Scanner

An NDT industrial scanner is a robotic device used in automated ultrasonic testing. It is equipped with a variety of sensors and scanners that can perform detailed inspections in various environments and conditions. NDT industrial scanners offer high-precision scanning capabilities, reducing human error and increasing inspection efficiency.

Transducer and Probe

The transducer and probe are essential components of the ultrasonic testing system. The transducer converts electrical energy into ultrasonic waves, while the probe emits and receives the waves. The choice of transducer and probe depends on the specific application and materials being inspected. Our experts can guide you in selecting the most suitable transducer and probe for your requirements.

Ultrasonic Couplant

Ultrasonic couplant is a gel or liquid medium used to improve the transmission of ultrasonic waves between the transducer and the material being inspected. It helps to eliminate air gaps and ensure optimal contact, allowing for accurate and reliable wave transmission. Choosing the right ultrasonic couplant is crucial for obtaining accurate results during UT inspections.

Are There Any Safety Considerations during Ultrasonic Testing (UT) Procedures?

While ultrasonic testing is generally a safe and non-hazardous procedure, there are a few safety considerations to keep in mind:

  • Ensure that operators are trained and follow proper safety protocols when working with UT equipment.
  • Protect the operator and surrounding individuals from exposure to excessive noise levels by using appropriate hearing protection.
  • Be aware of any potential electrical hazards and take necessary precautions when handling UT equipment.
