Non destructive testing
NDT is a method of testing material or product characteristics without damaging the product.
It is about testing whether the quality is okay relating to, for example, welding, material or design of products with high quality requirements.
This must be done throughout the product cycle, from production and installation to operation and maintenance, and the objective of the NDT is to identify defects.
NDT may in some cases be handled internally, but in many cases, the company chooses to use different subcontractors (accredited laboratories), and according to some regulations this is a requirement.
