ARC Inspection Services, LLC

Arc Inspection Services takes pride in offering top-notch conventional radiographic testing (RT) services. RT is a non-destructive testing method that harnesses the power of short-wavelength electromagnetic radiation to inspect materials for concealed flaws.

RT, with its ability to penetrate various materials, empowers technicians to uncover hidden discontinuities. These can include cracks, incomplete penetrations, burn-throughs, slag, and more. By identifying these issues, RT plays a vital role in minimizing the risk of future failures, saving your company both money and protecting the environment.

Arc Inspection Services is your trusted partner in ensuring the integrity and reliability of your materials and structures through the precision of conventional radiographic testing.

Dye Penetrant Testing (DPI) or Liquid Penetrant Inspection (LPI), commonly referred to as PT, represents a widely applied, cost-effective non-destructive testing process. It is instrumental in identifying surface-breaking defects in all non-porous materials.

In the PT process, the technician commences by meticulously preparing the surface for cleaning. The surface must be entirely free from any oil, grease, water, or other contaminants that could impede the penetrant from entering flawed areas.

The next step involves the application of a penetrant, typically done using a brush, allowing it to dwell and seep into the defect area.

After the prescribed dwell time, a thin layer of developer is applied to the sample, effectively drawing the penetrant from the flawed areas back to the surface. This ensures that the flaws become visible and easily detectable.

The final step involves a thorough cleaning of the part, leaving it ready for further inspection or use.

Magnetic Particle Testing, a non-destructive testing (NDT) process, serves as a powerful method for identifying surface and shallow subsurface discontinuities within ferromagnetic materials. This technique is highly effective for materials like iron, nickel, cobalt, and select alloys.

In Magnetic Particle Testing, a magnetic field is introduced into the part being examined. This can be achieved through direct or indirect magnetization. In direct magnetization, an electric current is passed through the test object, generating an internal magnetic field. On the other hand, indirect magnetization involves applying a magnetic field from an external source without the need for an electric current.

The magnetic lines of force created during this process are oriented perpendicular to the direction of the electric current. This current may be either alternating current (AC) or some form of direct current (DC), which can be rectified by AC.

When a surface or subsurface discontinuity is present within the material, it allows the magnetic flux to escape, as air cannot sustain as much magnetic field per unit volume as metals.

To identify these leaks, ferrous particles, whether in dry form or as a wet suspension, are applied to the part. These particles are attracted to areas of flux leakage, forming what is known as an "indication." The indication is meticulously assessed to determine its nature, cause, and the appropriate course of action.

Magnetic Particle Testing represents a precise and reliable method for flaw detection, ensuring the integrity of materials and components in critical applications.

Ultrasonic Testing (UT) stands as a non-destructive testing technique that hinges on the transmission of ultrasonic waves within the object or material under examination.

In typical UT applications, extremely brief ultrasonic pulse waves, boasting center frequencies typically ranging from 0.1 to 15 MHz, and occasionally extending up to 50 MHz, are propagated into materials. The primary objectives are to identify internal flaws within the material and to characterize its properties.

Ultrasonic Thickness Testing (UTT) is a specialized branch of UT specifically employed to gauge the thickness of a given material. This valuable technique is instrumental in ensuring materials meet precise thickness specifications, critical for numerous applications across various industries.
