Nans, could you share what inspired you to specialize in ultrasonic imaging and the field of Non-Destructive Testing (NDT) in general? What drives your passion for this area of expertise?
Like a lot of people, I came across non-destructive testing somewhat by chance. I think that I like this domain because I am a technically oriented individual who enjoys problem-solving and values expertise. What I find most interesting about NDT is the wide variety of projects we get to work on. It is utilised in many different fields, each with its own unique characteristics, making it very challenging.
TPAC prides itself on being 'Unique in NDT'. Could you elaborate on what sets TPAC apart from other companies in the industry, particularly in terms of the services and solutions you offer?
Our company stands out as a unique entity in the field of Non-Destructive Testing (NDT) not only for our cutting-edge technology but also for our distinctive organisational culture and client support system. We operate on a neuronal structure where individuals are empowered to take ownership and responsibility for their work. Our team is united and there is a lot of mutual assistance. Unlike traditional setups, our customer support system is designed to provide direct access to the right person. We prioritise direct communication with knowledgeable experts to address customer needs promptly and effectively. The company places a strong emphasis on research and development. It allows us to provide customised solutions to our customers and to address specific needs. Finally, we provide open and fully programmable equipment for ultrasonic testing, giving our clients unprecedented flexibility and control.
As a Research Engineer and Scientist at TPAC, could you give us insight into how your team approaches solving the most challenging ultrasonic technique needs for clients? What is the typical process involved in finding the best method and equipment for specific testing needs?
Our organisation takes a very practical approach. When faced with a challenging issue, we form a dedicated team of experts specialised in the relevant subjects. We have specialists in mechanics, electronics, software, acoustics, and NDT applications, allowing us to cover a broad spectrum of expertise. Some challenging problems may require specific developments, such as dedicated electronics or software, a specialised probe design, a new imaging technique, etc.
TPAC offers an extensive probe library and custom probe design services. Can you share a notable example of a custom probe solution you've developed for a unique design or application?
One notable example of a custom probe solution we've developed is a Matrix 512-channel array with varying pitch, specifically tailored for crack detection in reactor pressure vessels. Additionally, I recently had the opportunity to work on a project involving a curved array designed for inspecting hub slots in aircraft engines.
In industries like oil and gas, railways, aeronautics, and others, what are some common challenges that clients face in NDT inspections, and how does TPAC address these challenges with its tailored ultrasonic solutions?
NDT inspections commonly encounter various challenges, including difficulties in accessing components and structures, navigating hazardous environments, and managing time and cost constraints. At TPAC, we specialise in data acquisition and processing for NDT inspections. We have to ensure proper detection and characterization of defects that can take various sizes and shapes and have a wide spectrum of ultrasonic responses. In TPAC, we have experts in physics, acoustics, and signal processing to take the best advantage out of ultrasonic data.
Could you walk us through the process of developing a custom ultrasound solution at TPAC, from the initial feasibility study to the final implementation?
In developing a custom ultrasound solution at TPAC, our primary goal is to ensure that our approach is tailored to the customer's specific needs. Here's a typical path:
- Analysis of the material geometry and acoustic properties
- Analysis of the type of flaws and design of the strategy of detection and sizing
- Simulation (ultrasonic beam, flaws detection and sizing)
- Design of the calibration method
- Preliminary feasibility study
- Transducers design
- Adaptation and SW development if needed.
- Experimentations
- Iterative optimisation
TPAC provides advanced training in phased array, ultrasonics, physics, and probe technology. How does this training contribute to ensuring that clients get the most out of their NDT equipment and solutions?
We don't provide standard training courses. Instead, when a customer requires training on a particular topic, we offer personalised assistance tailored to their specific needs. This could involve training in the use of electronics, software development, instruction on our software, or teaching specialised inspection techniques.
With advancements in technology, particularly in areas like robotics and automation, how do you see the future of NDT inspections evolving, and how is TPAC positioned to adapt to these changes?
Robotics and automation technologies will play a major role in the future of NDT.
Robots can perform inspections with greater speed and precision, reducing the need for manual intervention and minimising human error. Robots are also very interested to do remote inspections in hazardous or hard-to-reach areas without putting human inspectors at risk. In TPAC, we are already working on interfacing our electronics with different robots. In addition, our electronics are compact with low power consumption making them very practical to be integrated into a robot.
I also believe the integration of artificial intelligence (AI) and machine learning algorithms will revolutionise NDT inspections by improving data analysis capabilities. Finally, augmented reality and 3D imaging should provide immersive visualisation of NDT data and therefore, transform the way data are analysed. In TPAC, we try to stay alert in order to produce equipment that will be compatible with future technologies.
For young professionals aspiring to enter the field of NDT and ultrasonics, what advice would you offer based on your experience and expertise in the industry?
Entering the NDT and ultrasonics field takes time because it's broad and always changing. Be patient to gain experience, stay up to date with new tech, and always be curious to learn more.
Finally, Nans, reflecting on your journey with TPAC, what aspect of your work brings you the most satisfaction, and what motivates you to continue pushing the boundaries of ultrasonic testing technology?
In our job, we are contributing to ensuring the safety, reliability, and integrity of critical infrastructure and assets through ultrasonic testing technology, that's very rewarding. Of course, NDT is a conservative field because it is dealing with safety, but it's very motivating to know that there are still many inspection techniques that could be improved thanks to new technologies.
