Keeping People, the Environment, Assets Safe with Non-Destructive 测试 (NDT)

Non-destructive testing (NDT) is critical to ensure the infrastructure and assets that we use daily remain safe. 执行测试，例如 数字放射显影术,传统 放射检测(RT), Liquid Penetrant 检查 (LPI), Magnetic Particle 检查 (MPI), 超声波检测(UT), 目视检查 give assurance that the 产品 and materials we use are fit-for-purpose.

NDT is essential for quality assurance; appropriate testing methods are used to gather information on a material without damaging it. It is critical for ensuring buildings, 桥梁, 火车, 电站, the infrastructure that each of us come into contact with regularly are reliable and perform as expected.
Some of the world's recent disasters could have been avoided if the proper NDT testing techniques were performed:

萨姆索涡轮机坍塌

On November 28, 2015, the nacelle, hub, blades of a wind turbine collapsed into the sea. The findings indicate a fracture in the weld connecting the tower top flange with the tower. The crack then developed over time, leading to a separation of the top of the tower. 

The welding at the time of installation was made according to the industry welding standards of 2002. 在很多情况下, non-destructive testing follows these standards and is the final operation conducted on a product to ensure it fits its designed purpose. The test method utilized is geared to interrogate the part for discontinuities in accordance with the controlling specifications and standards.

In the case of the turbine collapse, these standards have been subsequently changed, there have been no further cases of this occurring.

Metal Fatigue on Boeing 777: Denver

One of the fan blades on the Boeing 777 that failed shortly after take-off showed signs of metal fatigue on the Denver plane engine. This is likely to have been due to improper NDT inspection on the fan blade. Once the aircraft was in operation, 维护, including Eddy Current 测试, 超声检测, Magnetic Particle 检查, should be used on a routine basis to identify any signs of fatigue cracking and avoid failure in service.

It is essential to include NDT testing during the component's life-cycle to assist with in-service fatigue issues and investigations.

Although these are some of the more publicized disasters, 大多数时候, NDT works as expected to avoid these failures occurring in the first place. It is vital to perform NDT testing throughout the product life-cycle to ensure your 产品 and equipment remain safe.
