Nondestructive Testing (NDT) and
Inspection Services

CTC is an innovative and progressive Nondestructive Testing (NDT) and inspection company offering a full list of field inspection services throughout the West Coast. Our primary focus is northern California, however, we do provide mobile services wherever the project takes us.
CTC Services Inc. is a fully Certified Nondestructive Testing (NDT) Company staffed with American Society for Nondestructive Testing (ASNT) Level IIIs, Level IIs, American Welding Society (AWS) Certified Welding Inspectors, American Petroleum Institute (API) Certified Inspectors.
CTC is a Certified Federal Aviation Administration (FAA) repair station for Nondestructive Testing and inspection services on Aircraft.
Although every type of nondestructive method is unique in its own technology and limitations they complement each other to ensure we locate and properly identify the indication, defect, or nonconformity necessary to determine the disposition of the item we are inspecting.

Each Nondestructive Testing (NDT) method has unique qualities and capabilities for detecting the types of indications or defects that may be detrimental to the use or operation of the items being inspected.

An example of the methods and their capabilities are Magnetic Particle, Penetrant, and Visual Inspection. The primary use of these methods is for inspection of indications that are open to the surface; such as cracks, hot tears in castings, surface porosity, etc. Whereas, Radiographic and Ultrasonic inspections detect or identify subsurface indications or defects contained within the item of inspection. Additionally, Eddy Current inspection provides the capabilities to detect surface indications and in subsurface applications such as multi-layer aircraft skins and laminates. There are many different applications for this type of inspection.

The following list is an overview of the Nondestructive Testing (NDT) methods that CTC performs both in the field and laboratory:

  • Eddy Current (ET)
  • Magnetic Particle (MT)
  • Penetrant (PT)
  • Positive Material Identification (PMI)
  • Radiographic (RT)
  • Ultrasonic (UT)
  • Visual (VT)
