A typical mobile laboratory is equipped with personnel and equipment able to execute nearly all conventional NDE techniques including but not limited to Radiography (RT), Magnetic Particle Testing (MT), Dye Penetrant Testing (PT), Ultrasonic Thickness Testing (UTT) and Positive Material Identification (PMI). Contact TechCorr for your construction, fabrication or exploratory inspection project. GAMMA RADIOGRAPHY TechCorr’s gamma radiographic method uses radioactive isotopes to detect internal defects and inhomogeneities in weld quality and structural integrity or corrosion of asset material. We identify and report the small changes in thickness and density of the material that have a significant effect on the strength of penetrating radiation, according to the inhomogeneity of the radiographic image displayed as brighter or darker areas on the film.

Awkward weld geometry and the presence of a weld crown or bead typically require shear wave testing, which entails placing a probe to the side of a weld and generating beams at an angle toward the weld. Request Quote Contact Us MAGNETIC PARTICLE INSPECTION Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current, which may be either alternating current (AC) or some form of direct current (DC) (rectified AC). Request Quote Contact Us DYE PENETRANT INSPECTION TechCorr’s Penetrant Testing (PT) inspection services find surface-breaking discontinuities on relatively smooth, nonporous surfaces. Penetrant Testing (PT) – also known as dye penetrant testing – is based on the properties of surface wetting and capillary action, which causes a liquid to rise when confined to a small opening. After applying the penetrant and wiping away the excess, the penetrant that rises to the surface can indicate surface-breaking anomalies. TechCorr’s PT services are widely applicable to identify discontinuities in a variety of assets given its ease of use and minimal equipment requirements. Our technicians perform PT on assets in a variety of industries, with a wide range of shapes, sizes, and materials, including: Metals Composites Glass Ceramics Rubber Plastics Request Quote Contact Us ULTRASONIC THICKNESS TESTING Ultrasonic Thickness Testing (UTT) is a performing non-destructive method analysis of the local thickness of solid material and is based on the time taken by the ultrasound wave to return to the surface. UTM is frequently used to monitor metal thickness or weld quality in industrial settings such as mining. TechCorr’s technicians are equipped with portable UTM probes to reach steel plating insides, tanks, decks, and the superstructure. They can read its thickness by simply touching the steel with the measurement head (transducer). Accuracy is generally assured by first removing visible corrosion scale. The advantages of this method are: Does not require access to both sides of the sample Can be engineered to cope with coatings, linings, etc. Good accuracy (0.1 mm and less) can be achieved using standard timing techniques Can be easily deployed, does not require laboratory conditions EMAT does not require the use of couplant. EMAT can conduct thickness measurements through corrosion and other surface coatings on metals No need to remove the coating of the metal.

When doing a hardness test, the hardness tester applies a fixed load and the depth of penetration is measured. Request Quote Contact Us POSITIVE MATERIAL IDENTIFICATION Positive material identification (PMI) provides alloy chemistry and grade ID information in seconds using a hand-held scanner. PMI is also commonly used to ensure: the parent material in vessels and pipes is composed of the correct composition the correct filler material was used during equipment repair.
