Nondestructive Testing (NDT) is the examination of an object with technology that does not affect the object’s future usefulness. NDT provides an excellent balance between quality control and cost-effectiveness. NDT is used in all phases of a product’s design and manufacture, including materials selection, research and development, assembly, quality control, and maintenance.

From appliances, autos and aircraft, to the endeavors of our space exploration program, the detection of defects and hidden flaws due to manufacturing or service is paramount to the safety of most products.

Nondestruction testing processes we offer include 1) Penetrant Inspection, and 2) Magnetic Particle Inspection.

This is a nondestructive testing method that locates discontinuities open on the surface of a metal component. First, a penetrating dye is allowed to infiltrate the discontinuity. Next, the excess penetrant is removed, and then a developing agent is applied. The developing agent causes the penetrant to weep back out of the discontinuity and register as an indication. Penetrant inspections are generally suitable for both ferrous and non-ferrous materials, but limited to the detection of open surface discontinuities in non-porous solids.

This is a nondestructive method of inspection to determine the existence and extent of surface and near surface cracks in ferromagnetic materials. Finely divided magnetic particles, applied to a part during magnetization, are attracted to any magnetic-leakage fields created by discontinuities. The magnetic particles are attracted to the discontinuous areas and outline these areas so surface and near surface cracks can be identified.
