Non-destructive testing (NDT) plays a crucial role in most industries where safety, reliability, and product quality take top priority. Using NDT, businesses can inspect materials, components, welds, and structures without damage to the items being tested.
However, everything depends on the NDT company you choose. Cheap NDT inspection services can lead to missed defects, unnecessary repairs, production delays, or serious safety risks.
Here are four key factors you should consider when looking for NDT services.
Check the NDT Company’s Qualifications and Experience
One of the first things to consider when choosing an NDT services provider is qualifications and industry experience. Non-destructive testing is a specialized field, and the reliability of test results depends on whether technicians have the appropriate training and certification.
Before you start talking about quotes, ask potential providers about the qualifications of their NDT technicians. Still on the same topic, determine whether the company operates as per relevant industry standards and procedures.
Industry experience is also important. A technician with experience working on machines similar to the ones you are using will offer more bang for the buck since they are more likely to understand potential defects and inspection challenges.
Consider Compliance and Quality-Control Procedures
NDT inspections are often performed on critical components where inaccurate results can have serious consequences. For this reason, quality control and regulatory compliance should be given top priority when evaluating service providers.
As we mentioned before, ask the company whether they follow the relevant standards, specifications, and procedures applicable to your project or industry. Top NDT service firms such as ARI will always provide you with the required documentation and safety procedures.
This documentation is particularly important if your business requires inspection records for regulatory, maintenance, insurance, or auditing purposes.
Evaluate the NDT Methods and Technology Available
There is no one test for all, with non-destructive testing services. The process encompasses several methods, each of which is designed to identify particular types of defects or material characteristics.
When looking for NDT services, make sure the provider offers the techniques appropriate for your specific application. Don’t let anyone dupe you into accepting that the most advanced method is automatically the ideal choice.
In fact, the best NDT technicians or service providers will first understand your inspection requirements and then recommend an appropriate testing method.
Compare Pricing and Turnaround Times
Last, ensure that at the end of the NDT inspection process you are getting value for your money.
When evaluating NDT firms, the evaluation process shouldn’t be a comparison between the most expensive vs the cheapest firm. Instead, your goal is to look at which technician or company offers the best value for the price.
When comparing quotes, make sure you understand exactly what is included. A company that looks cheap may exclude other services such as reporting, equipment mobilization, and additional testing in its quote.
Also worth asking about is the turnaround time. In industries such as oil and gas, construction, and power generation, delays can result in significant downtime and financial losses. Before finalizing the deal, ask potential providers how quickly they can get to your site, perform the inspection, analyze results, and deliver the final report.
