How to Choose the Right NDT Inspection Company
You need to choose the right NDT inspection company based on the scope of your project, industry needs and your inspection goals. First, determine the inspection method that corresponds best with the type of defect or asset condition you wish to inspect. For instance, ultrasonic testing might be suitable for the detection of flaws inside the material, while radiography could be used to get a detailed picture of the integrity of welds.
Checking for certifications and qualifications, such as ASNT, NAS-410, ISO 9712, and customer approvals are also important. Experience is important since there are differences between various industries, such as pipelines, manufacturing, power generation, and aerospace.
Check if the provider will be able to carry out any advanced NDT techniques like PAUT, TOFD, AUT, eddy current or if they can come to your facilities to conduct the check. Lastly, consider the turnaround times, reporting quality and digital inspection features to guarantee the successful execution of the project.
