What’s the most popular Advanced NDT technique in the UK (according to Google)?

When we launched NDT Innovation, we set out to embrace the most cutting-edge advanced NDT technologies. 

What is the most popular advanced or digital NDT technique in the UK? Amongst the plethora of technologies available, what NDT techniques are people searching for at the moment? 

In this blog post, we will unravel the story behind the most popular advanced/digital NDT technique in the UK by looking at what people are searching for on the world’s largest search engine. 

Understanding Advanced/Digital NDT

Before we delve into finding the most popular technique, let’s understand what advanced/digital NDT is.  

Traditional NDT methods involve inspecting materials and structures without causing damage, typically using techniques like visual inspection, magnetic particle testing, and ultrasonic testing.

However, advanced/digital NDT takes this a step further by leveraging cutting-edge technologies such as digital radiography, computed tomography, and phased array ultrasonics. 

These techniques offer higher sensitivity, faster inspection times, and digital records that facilitate easier analysis and reporting. They are often more cost-effective, time-efficient, sustainable and useful. 

Why Google?

As the biggest search engine in the world, Google serves as a barometer for public interest and trends. Google controls a staggering 91.54% of the global search engine market and processes 5.9 million searches per minute.

By examining search patterns and queries, we can gain valuable insights into the popularity of pretty much every topic under the sun, making it perfect for determining what different NDT techniques users are looking for. 

How can we do this?

SEO digital platforms collect data from search engines like Google and produce an overview that shows how popular a particular search term (known as a keyword) is. They calculate how many times each keyword is typed into search engines. This figure is known as the “search volume”. 

The search volume provides insights into how many people actively seek information related to a specific subject.

By focusing on keywords that suggest users are looking to hire a company to conduct a particular NDT test, we can put a figure next to the number of people interested in that service.

According to Google, the advanced/digital NDT technique that stands out prominently in the UK is Pulsed Eddy Current (PEC) Testing.

Let’s find out more about this technique. 

Pulsed Eddy Current: a closer look 

Pulsed Eddy Current works by using the basic idea of electromagnetic induction.

When an alternating current is passed through a coil, it generates a magnetic field around the coil. This magnetic field induces eddy currents in the conductive material being tested. 

The presence of anomalies, such as corrosion or material degradation, alters the induced eddy currents, leading to variations in the magnetic field. These variations are then measured and analysed to detect and characterise flaws within the material.

At NDT Group, we offer Pulsed Eddy Current testing alongside other advanced NDT techniques. Contact us to find out how we can help you. 

Advantages of PEC

The popularity of pulsed eddy current testing in the UK can be attributed to several key advantages it offers:

  • Thickness Measurement: PEC excels in measuring the thickness of conductive materials, providing precise data on material thickness without the need for direct contact.
  • Large Area Coverage: The technique is well-suited for inspecting large surfaces quickly, making it particularly effective for applications where efficiency and speed are paramount.
  • Penetration of Coatings: PEC can penetrate non-conductive coatings, allowing for inspections beneath layers of paint or other protective coatings without the need for their removal.
  • Sensitivity to Corrosion: PEC is highly sensitive to corrosion, making it a valuable tool for industries where corrosion assessment is critical, such as in oil and gas pipelines or maritime structures.
  • Adaptability: PEC is adaptable to various materials, including metals and alloys, making it versatile for applications in industries such as manufacturing, construction, and infrastructure.

Pulsed eddy current testing can be used in a number of different industries, such as oil and gas, infrastructure inspection, aerospace, and manufacturing quality control, making it a versatile option. 

Digital NDT techniques on the rise

As industries in the United Kingdom continue to prioritise safety and quality, the adoption of advanced/digital NDT techniques is on the rise. 

According to Google, Pulsed Eddy Current Testing emerges as the most popular choice, driven by its ability to provide rapid and accurate inspections, particularly in applications where thickness measurement and corrosion assessment are crucial, highlighting its significance in ensuring the structural integrity of critical assets across various industries. 

This trend underscores the industry’s commitment to leveraging cutting-edge technologies to ensure the integrity of critical assets, laying the foundation for a safer and more reliable future.
