How can you choose the right NDT technique?

1 Define your objectives

Before you decide on an NDT technique, you need to have a clear idea of what you want to achieve with it. What are the defects or flaws that you want to detect, measure, or evaluate? How critical are they for the performance and integrity of your product or component? What are the standards and specifications that you need to comply with? How often and when do you need to perform NDT? These are some of the questions that will help you define your objectives and requirements for NDT.

2 Assess your material and geometry

The next step is to assess the characteristics of the material and geometry of your product or component. Different NDT techniques have different capabilities and limitations depending on the type, size, shape, and structure of the material. For example, some techniques are more suitable for metals, while others are more effective for composites or plastics. Some techniques can penetrate deep into the material, while others can only scan the surface or near-surface. Some techniques can handle complex or curved geometries, while others require simple or flat geometries. You need to choose an NDT technique that is compatible with your material and geometry.

3 Consider your environment and resources

Another important factor to consider is the environment and resources that you have for performing NDT. Where and how will you conduct NDT? Will it be in a laboratory, in a workshop, or in the field? Will it be offline or online, meaning will it interrupt or integrate with your production process? What are the environmental conditions, such as temperature, humidity, noise, or radiation, that may affect your NDT technique? What are the resources, such as equipment, personnel, time, or budget, that you have available for NDT? You need to choose an NDT technique that is feasible and practical for your environment and resources.

5 Consult an expert

Finally, if you are still unsure or need more guidance on choosing the right NDT technique, you can consult an expert in the field. An NDT expert can help you review your situation and recommend the most suitable technique for your needs. They can also provide you with training, advice, and support on how to perform NDT effectively and efficiently. You can find an NDT expert through professional associations, certification bodies, or service providers that specialize in NDT.

Choosing the right NDT technique is a crucial decision that can affect the quality, safety, and reliability of your manufacturing operations. By following these steps and asking these questions, you can make an informed and confident choice that will help you achieve your NDT objectives.
