Dahlgren Non-Destructive Testing Services
Certified Welding Inspector (CWT) in Dahlgren, VA
Many jobsites ranging from pipelines, fabrication shops, bridges and structural steel fabricators need or require a Certified Welding Inspector (CWI) to help run their quality program, certify welders, perform visual inspections on fit-ups, root passes and final inspections of completed welds. CWIs come from different backgrounds, some have welding experience only, Some have inspection experience only and some have an engineering degree. All CWIs need to know how to interpret the welding procedure, welding qualification, acceptance criteria for defects, welding machines, and consumables. Integrity Testlabs can provide a CWI for your long- or short-term projects.
Dahlgren, VA Ultrasonics
Using high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization. The sound energy is introduced and propagates through the material in the form of waves. When there is a discontinuity or crack in the wave path, part of the energy will be reflected. back from the flaw surface. The reflected wave signal is transformed into an electrical signal by the transducer and is displayed on a screen. Advanced Ultrasonics takes many on the job hours and classroom training to become a skilled technician in Ultrasonics. Integrity Testlabs has technicians to cover all your Ultrasonic (UT) needs.
ANST Level I and Assistants
Becoming certified or learning about Nondestructive testing can be achieved in two ways. Enrolling in a school that provides a certificate or degree or getting hired on with a company with no knowledge of the industry and learning on the job. Typically 40hrs of radiation safety is the first step/certificate that is needed to get started. Once the Assistant has had some time in the industry the company will provide them with classroom training either in house, computer based or sending them to a course provided by a known 3rd party. When the Assistants meets the required OJT hours and classroom time. They will test with the company they are with by completing a specific, general and practical exams. When this is completed, they are now a Level II technician.
API 510 Inspector in Dahlgren, VA
This is an individual certification that is achieved through API testing program that test individuals on their knowledge of inspections, maintenance, repairs and alteration of pressure vessels. This certificate is recognized worldwide. Most individuals have many years of inspection experience of the internals of a pressure vessel, performing Ultrasonic Thickness readings, Visual Inspections and other various NDT methods. Having an understanding of how the operations of the facility work also helps you understand where failures might occur in the different variety of vessels. Integrity Testlabs has API 510 in house and contractors that can help your company keep up with planned and unplanned maintenance and help start or maintain corrosion programs.
ACFM; Alternating current field measurement in Dahlgren, VA
Integrity Testlabs was one of the first companies to provide this inspection technique in the Northeast. ITL technicians have completed hundreds ACFM inspections on equipment shells in oil refineries in the Northeast. ACFM is a electromagnetic technique used for detecting cracks breaking the surface. Capable of also sizing the defect. ACFM can be used on ferrous and nonferrous metals. ACFM can be fast and effective inspection. It does need the area to be cleaned and electric available to run the ACFM unit. Wet Fluorescent Magnetic Testing (WFMT) can be used as an alternate inspection to confirm the findings of the ACFM.
C-scan, Shearwave and Phased Array
Automated Corrosion Mapping uses C-scan to do corrosion maps to find flaws on the shells of equipment and piping. AUT can produce very detailed reports for clients to visually see where the corrosion is happening. Shearwave uses high frequency sound waves to identify flaws in the material. Sensitive to surface and subsurface discontinuities it’s a superior inspection tool wen compared to other NDT processes. Phased Array is known for its capabilities to send multiple singles into material to produce highly repeatable results and detailed and accurate cross sections of components. This makes Phased Array a needed to tool to inspect complex shaped parts.
