Frequently Asked Questions About NDT Services

What are the main types of NDT testing methods?

The six primary NDT methods are Ultrasonic Testing (UT), Radiographic Testing (RT), Magnetic Particle Testing (MT), Liquid Penetrant Testing (PT), Eddy Current Testing (ET), and Visual Testing (VT). Advanced methods include PAUT, TOFD, and Guided Wave Testing.

How do I choose the right NDT method for my application?

The right NDT method depends on the material type, defect type you are looking for, geometry of the component, and applicable codes/standards. Use our free NDT Method Selector tool or consult with certified inspectors on NDT Connect.

How much does NDT testing cost?

NDT testing costs vary by method, location, and complexity. Ultrasonic testing typically ranges from $300-$1,500 per inspection, while radiographic testing can range from $500-$3,000. Get instant quotes from multiple providers on NDT Connect.

What certifications should an NDT inspector have?

NDT inspectors should hold certifications such as ASNT SNT-TC-1A or ACCP (USA), ISO 9712 (international), PCN (UK/Europe), or API certifications for specific equipment types. All NDT Connect providers are verified and certified.

Can I book NDT inspections online?

Yes, NDT Connect allows you to search for certified NDT providers, compare quotes, and book inspections online with real-time tracking for any NDT method worldwide.
