Due to the negative demand shock from the COVID-19 pandemic, the global ultrasonic testing market declined hugely by -14.9% across all regions in 2020. However, as the pandemic subsides and demand returns to pre-pandemic levels, our market analysis shows ultrasonic testing will rebound at an accelerated 9.43% CAGR between 2020 and 2027.

Ultrasonic testing (UT) is primarily involved in service defect monitoring of industrial equipment, machinery, aircraft spare parts, and components. It is a technologically advanced technique that transmits ultrasonic waves through a testing material to penetrate a material’s thickness. The UT methodology consists of high-frequency sound waves, which are transmitted into several materials, such as aircraft metal structures, metal components, and industrial equipment, to identify material cracks.

Slower Growth in the Aviation Industry Amid COVID-19 Pandemic to Hamper the Market

According to a pre-pandemic report of the International Bank for Reconstruction and Development (IBRD), around 4.25 million air passengers were carried around the globe. The air passenger count has been hampered owing to the ban on international travelling during the COVID-19 pandemic. The aviation industry faces major challenges due to the COVID-19 effect, such as economic recession, declining air passenger traffic, and fluctuating oil prices.

The International Air Transport Association’s (IATA) Financial Outlook Report (2020) estimated a USD 84.3 billion loss for the global air transport industry. Total revenue fell by 20% during the financial year of 2019-2020. Airbus, for instance, registered zero orders in the first quarter of 2020. The UT methodology is a prime technique to identify damages to the aircraft mainframe and other components. The declining deliveries of fixed-wing commercial aircraft will inevitably hamper the growth of the ultrasonic testing market in the financial year 2020-2021.

Strong Demand for Ultrasonic Testing in the Aerospace Industry to Boost Market Growth

The aerospace industry maintains the highest quality standards regarding material, structure, and strength. The technique is based on the ultrasonic methodology and is also called non-destructive examination (NDE), non-destructive evaluation (NDE), and non-destructive inspection (NDI). The failure in strength, surface, and development of cracks may lead to several risks in the form of fatal accidents and the subsequent loss of lives.

UT is majorly used in the aviation industry to inspect the composite parts of an aircraft. The technique is used to maintain the aircraft's flying safety by analyzing the destruction of several aircraft parts, such as landing gear, aircraft mainframe, and aircraft engine. The transition towards the Internet of Things (IoT) is a new opportunity in the aviation industry to analyze the health of avionics components, such as autothrottles, collision avoidance systems, and flight management systems.

Rapid Expansion of Railway Infrastructure to Augment the Demand for UT

The increasing demand for affordable transportation through railway infrastructure is a major factor driving market growth. According to the World Rail Market report on behalf of the European Rail Supply Industry Association, UNIFE has estimated an average growth of 2.6% worldwide from  2021 to 2023. The Middle East & Africa, and Latin America regions are projected to grow the fastest at 5.1% and 4.8%, respectively, annually.

According to the Federal Railroad Administration report (2019), accidental events have been mainly caused by railway track defects in the U.S. The leading causes of track defects include bending, thermal stress, residual stress, and corrosion. The transportation infrastructure is heavily dependent on the railway system, monorail, speed trains, metro rails, and bullet trains. Ultrasonic inspection plays an important role in examining track flaws, track cracks, and uneven structure, leading to tragic rail accidents occurring worldwide. Thus, the rapid expansion of railway infrastructure in the U.S. and Asia Pacific will fuel the demand for this ultrasonic type of testing in future years.


High Cost of Ultrasonic Equipment May Impede Market Growth

The UT method is highly dependent on the most sophisticated technologies and instrumentations. The machinery and instruments are an expensive set of equipment due to several sensors, components, and high-quality parts integrated into them. This Ultrasonic type of testing is primarily involved in service defect monitoring of industrial equipment, machinery, and several systems in which conventional methods are utilized. The major key players are also experimenting with new methods, such as using nanorobots, which are built with UT capacity for defect monitoring and inspection processes. The nanorobots are majorly used for the inspection process of pipeline systems in the oil & gas industry. High costs are involved in maintaining these robots with the help of the Internet of Things (IoT).

UT methods and techniques have different sizes, and a variety of machinery is involved in the process. Therefore, service providers need rental types of machinery, equipment, and accessories for better evaluation by testing. This factor is expected to limit the future growth opportunities of the ultrasonic testing market.
