Nondestructive Testing

At Inspec Testing Inc., we offer a comprehensive range of nondestructive testing (NDT) services that allow us to perform inspections without causing damage. These provide an excellent means of evaluating materials, systems, and components without disruption, which is key to overall safety, efficiency, and reliability in primary industries like manufacturing, construction, energy, and aerospace. We are a well-established California NDT services company, and each NDT method we employ is designed to effectively address industry-specific challenges while bolstering the safety and quality of industrial applications.

Visual Testing

Visual testing (VT) refers to visually inspecting specific building components, making it a basic form of NDT services that plays a critical role in overall effectiveness. VT is performed by trained specialists who are certified in compliance with ASNT Recommended Practices, and the tests are conducted with the naked eye, along with some optical aids. This is often the first step in the NDT process, and it helps to ensure that all applicable specifications are met.

Videoscope

Videoscope allows us to expand on visual inspections with specialized tools. With a videoscope and probes of up to 30 feet, we can access areas that basic visual testing does not permit, including the interior surface of pipelines. 

Magnetic Particle Testing

Magnetic particle testing (MT) is used to locate discontinuities at the surface and near the surface of ferromagnetic materials like steel. The process involves magnetizing the part that is being tested and applying ferromagnetic particles to highlight any defects. MT can be performed in our offices or on your jobsite.

Demagnetization

Demagnetization is a crucial step in the process of removing residual magnetism from ferromagnetic parts, which is usually performed after magnetic particle testing. The goal is to prevent concerns like the following:

• Interference with electronics
• Chips that cling during machining
• Arc blow and other welding problems

Liquid Penetrant Testing

Liquid penetrants are applied to the surface of solid, nonporous materials in order to identify any discontinuities like cracks or cavities via ultraviolet or visible light. This is a highly effective means of detecting defects that are likely to be missed by the naked eye, and it is especially relevant to aerospace applications.

Ultrasonic Testing

Ultrasonic testing uses high-frequency sound waves to detect discontinuities at the surface or subsurface level. This form of testing can check for thickness, inspect welds, monitor corrosion and erosion, assess residual stress and bolt tension, and measure dimensions. Common applications include inspecting bridges, machinery, and pressure vessels. 

Conventional and Computed Radiography

Conventional radiography penetrates materials with X-rays or gamma rays, which create shadow images of internal defects on film. Computed radiography, on the other hand, employs a digital technique that requires no film. Instead, special plates that are designed to capture images are ultimately scanned by a laser reader, which creates a digital file that can be analyzed instantly.
