What is Non Destructive Testing?

Non Destructive Testing is the art of inspecting objects without destroying, or weakening the material. NDT encompasses many different methods of testing. Non Destructive Testing is preferred over Destructive testing due to the fact that the objects our customers send us are not destroyed or damaged in order to gauge material integrity. This allows the customer to use every piece.manufactured without waste.

Processes in Detail

1. Gamma Ray (Steel)

Ir192 and Co60 are man made radioactive isotopes used primarily for industrial applications. Iridium is capable of penetrating up to 4” of steel while the shorter wavelength Co60 will penetrate a maximum of about 8”.

2. Gamma Ray (Concrete)

With the capability of penetrating up to 22” of concrete, performing Rt on a concrete slab will supply the customer with information such as rebar, conduit and PT cable location all contained on a piece of film the customer gets to have for future reference.

3. X-Ray

A 320 Kv X-ray tube produces a radiograph with greater contrast than Iridium or cobalt and together with a fine grain film will produce a film sensitivity of 1T. X-ray is capable of penetrating up to 3-4 inches of steel.

4. Ultrasonics

Ultrasonic testing uses a piezoelectric crystal to introduce soundwaves into an object. By measuring the amplitude and shape of the back reflection, ultrasonics can give a detailed description ranging from defect size and location, to part thickness.

5. Phased Array

Using the newest technology available, phased array ultrasonics is used to give detailed information about a variety of materials ranging from carbon steels and high alloy steels to carbon fiber composites and plastics. This information unlike traditional ultrasonics can be encoded and stored digitally to give an objective test that can be reviewed by multiple parties after the test has been completed.

6. Penetrant

Penetrant testing is used primarily to test for surface defects on stainless steel and aluminium. Penetrant testing provides an expedited and economical testing solution for petrochemical, aerospace, and automotive industries.

7. Magnetic Particle

Magnetic Particle testing is unparalleled in the detection of defects up to a .25” deep in most ferrous materials. MTI has the ability to detect fine cracks and non fusion areas in welds, thereby saving our customers time and money.

8. Hardness Testing

Hardness testing is essentially the ability to gauge the object’s resistance to deformation, it can be used to calculate an object’s tensile strength. Hardness testing is used extensively in the oil and gas industries, where different metal alloys react differently to the chemicals they are being subjected to.

9. Alloy Analysis (PMI)

PMI is most commonly used in fabrication industries for alloy identification. Due to the quick scanning capabilities of the equipment, vast quantities of alloys can be sorted, as well as verifying material supply.

10. Ground Penetrating Radar (GPR)

GPR is a quick reliable tool to check for voids, reinforcing steel, and electrical services through up to 12” thick concrete. Excellent technique for slab on grade inspections. When the x-raying concrete is not an option, such as public spaces or in areas that x-raying a material is not an option, such as seeing through concrete slabs.

11. Welder Certification

Providing certification of numerous types of welding (SMAW, GMAW, GTAW, SAW)

12. NDT Level 1 & 2 Training
