ULTRASONIC TESTING (UT)
Ultrasonic Testing is a volumetric NDE method that introduces high frequency sound waves into material for the purpose of flaw detection, thickness measurements and condition assessments. ATS utilizes UT for new construction (Code) and in-service examinations for various types of environmental damage. ATS applies UT with manual and automatic scanning techniques.
PHASED ARRAY (PAUT)
Phased Array UT is an advanced UT technique that enhances detection potentials, particularly when examining welds. This is due to the “phasing” of multiple transducer elements, within a PAUT probe, by using focal laws that allows the control of sound beam construction, direction and focusing. This creates the ability to steer a beam through multiple angles simultaneously, which increases the probability of detection of “off-angle” flaws. ATS uses PAUT primarily for the examination of pressure vessel and piping welds.
ASNT LEVEL III SERVICES
Our ASNT Level III personnel are among the most knowledgeable in the industry. Our 80 years of collective experience spans through multiple industries such as aerospace, construction, manufacturing, marine, power, oil & gas, and process plants. Whether it’s training, testing or certifying personnel, or developing special techniques and procedures for our clients, ATS Level III’s are fully versed in the Codes and are able provide guidance to our clients.
MAGNETIC PARTICLE TESTING (MT)
Magnetic Particle testing is a non-destructive testing process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials. The process puts a magnetic field into the material being tested to identify surface discontinuities. The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals. Ferrous iron particles are applied to the material and if an area of flux leakage is present the particles will be attracted to this area.
LIQUID PENETRANT TESTING (PT)
Liquid penetrant inspection or penetrant testing is a method of non-destructive testing techniques that uses penetrant and developer compounds to locate surface-breaking defects in non-porous materials. Dye-Penetrant testing is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity and fatigue cracks on in-service components.
RADIOGRAPHIC TESTING (RT)
Industrial Radiographic Testing is a method of non-destructive testing where many types of manufactured components can be examined to verify the internal structure and integrity of the specimen. The vast majority of radiography concerns the testing and grading of welds on pressurized piping, pressure vessels, high-capacity storage containers, pipelines, and some structural welds.
POSITIVE MATERIAL IDENTIFICATION (PMI)
Positive Material Identification is an NDE technique for alloy analysis. ATS utilizes X-ray Fluorescence (XRF) technology to identify materials for verification, tracking or discovery work. PMI is extremely useful in process plants to confirm correct pipe material installation for the product(s) flowing through it.
REMOTE VISUAL INSPECTION (RVI)
Remote Visual Inspection is a technique under the Visual Testing (VT) Method. This is performed using cameras, borescopes, videoscopes, robotic crawlers and unmanned aerial vehicles. Depending on the situation, component and the damage mechanism sought, ATS selects the optimal tool for the project.
