Non Destructive Testing (NDT)

 

NDT stands for Non-Destructive Testing. It refers to an array of inspection methods that allow inspectors to test, evaluate and collect data about a material, system, or component without permanently altering it.

Each method has advantages and disadvantages. Some will be ideal for certain applications but of little or no value in another situation. So it is important to choose the NDT methods that are right for the job.

Indications found with all methods are noted as either relevant or irrelevant. Relevant indications are evaluated until they are deemed acceptable or unacceptable. 

If you would like advice from an experienced professional about about which NDT method will best meet your needs, ask us!
