Positive Material Identification

ABC Testing was incorporated in December 1982 by Carleton A. Richardson. Since then the company’s number one commitment has been customer service. The company is certified as ASNT SNT TC 1A, level III in Ultrasonic, Radiography, Magnetic Particle, Liquid Penetrant and Visual Testing.

ABC Testing provides inspectors certified by the NYDOT in ultrasonic testing. This testing can be used to identify defects such as cracks, laminations, shrinkage cavities, gas holes, slag inclusions, incomplete fusion, incomplete penetration and lack of bond in a wide variety of materials. Radiographic testing is used when volumetric inspections are necessary to insure part reliability and a permanent record gets stored on film.

Magnetic particle helps detect surface flaws that would not be visible otherwise on ferrous materials. Liquid penetrant, on the other hand, helps detect surface flaws on non-magnetic materials that would not be seen visually. Visual testing is a cost effective examination used to check weld size and appearance. The company also offers various destructive tests to aid in welding procedure qualifications. It has several AWS Certified Welding Inspectors on its staff. They use Bend Testing, Tensile Testing and Charpy Impact Testing to test ductility, strength and material resistance, respectively. Destructive tests also include Hardness Testing which is used to verify whether heat treatment was done properly and Salt Spray Testing which helps in determining corrosion resistance.
Positive Material Identification is another technique that is used to give immediate results about the alloy in question with minimum surface penetration. It uses X-ray fluorescence to identify ferrous and non-ferrous materials without having to cut the sample out for analysis. Eddy current is normally used to check chiller system tubing for detecting defects, sorting materials, testing thickness and conductivity.
