Flaw Detection

Arizona non-destructive testing

Ultrasonic Inspection [UT]

Ultrasonic inspection is used to locate surface and subsurface defects in many materials including metals, plastics, and wood. Ultrasonic inspection is also used to measure the thickness of materials and otherwise characterize properties of material based on sound velocity and attenuation measurements.

High frequency sound waves are sent into a material by use of a transducer. The sound waves travel through the material and are received by the same transducer or a second transducer. The amount of energy transmitted or received and the elapsed time at which the energy is received are analyzed to determine the presence of flaws.

Advantages of UT

  • Depth of penetration for flaw detection or measurement is superior to other NDT methods.
  • Only single-sided access to the test part is required.
  • Provides information about flaw size and location.
  • Minimum part preparation is required.
  • Method can be used for much more than just flaw detection.

Limitations of UT

  • A liquid or gel couplant must be used to eliminate air trapped between the transducer and part to be inspected.
  • A part surface must be accessible to the probe and couplant.
  • Inspector skill and training required is more extensive than other techniques.
  • Part surface finish and roughness can interfere with inspection.
  • Thin parts may be difficult to inspect.
  • Linear defects oriented parallel to the sound beam can go undetected.
  • Reference (calibration) standards are typically needed.

Acoustic Resonance Inspection [AT]

Acoustic Resonance Inspection uses a technique called Resonant Ultrasound Spectroscopy, also popularly known as Resonant Inspection (RI). Resonant Inspection can detect imperfections such as variances in overall shape, weight, presence of cracks, and density of parts. It can also detect if process have been missed, such as  machining, secondary operations or heat-treating processes. It is very well suited to identifying manufacturing process variation.

Resonant frequencies are determined by dimensions and material properties of the “whole part,” and every part has a unique vibration signature; its resonant frequency. This resonance will be almost exactly the same from good part to good part. However, it will change when there is an internal or external imperfection or difference of some kind.

Pipe organs, bells, carillons and xylophones are examples of how controlled incremental changes in a part create incremental changes in “resonance” or tone. When a bell cracks, however, it doesn’t have a clear ring; the ring is flat or dull sounding. It loses the ability to hold its tone, as its resonance has been altered from that of a good bell.

The same is true of a part that has a flaw. Using the Resonant Inspection technique, we can detect this difference in resonance between the subject part and the population of known good parts.

Advantages of AT:

  • Evaluates the structural integrity of the whole part.
  • No part preparation needed prior to testing.
  • Has high throughput and can keep pace with serial production volumes.
  • Detects significant structural defects of all types.
  • Minimal inspector training needed – inspection is go / no-go.

Limitations of AT:

  • Cannot determine type, size or location of flaws.
  • Very small defects may not be detectable.

Eddy Current Inspection [ET]

Alternating electrical current is passed through a coil producing a magnetic field. When the coil is placed near a conductive material, the changing magnetic field induces current flow in the material. These currents travel in closed loops and are called eddy currents. Eddy currents produce their own magnetic field that can be measured and used to find flaws and characterize conductivity, magnetic permeability, and dimensional features.

Eddy current inspection is used to detect surface and near-surface flaws in conductive materials, such as metals. Eddy current inspection is also used to sort materials based on electrical conductivity and magnetic permeability, and can be used to measure the thickness of thin sheets of metal and nonconductive coatings such as paint.

Advantages of ET:

  • Detects surface and near surface defects.
  • Test probe does not need to contact the part.
  • Method can be used for more than flaw detection.
  • Minimum part preparation is required.

Limitations of ET:

  • Only conductive materials can be inspected.
  • Ferromagnetic materials require special treatment to address magnetic permeability.
  • Depth of penetration is limited, making it difficult or impossible to detect sub surface flaws.
  • Flaws that lie parallel to the inspection probe coil winding direction can go undetected.
  • Inspector skill and training required is more extensive than some other NDT techniques.
  • Part surface finish and roughness may interfere with inspection.
  • Reference (calibration) standards are needed for setup.

Visual Inspection [VT]

Visual testing is the most commonly used test method in industry. Because most test methods require that the inspector look at the surface of the part being inspected, visual inspection is inherent in most of the other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by direct viewing, using line-of sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, borescopes, and computer-assisted vision systems (remote viewing). Corrosion, misalignment of parts, physical damage, tears, laps and cracks are just some of the discontinuities that may be detected by visual examinations.

Advantages of VT

  • No part preparation is needed, and most inspections are carried out with simple aids.
  • Detects volumetric surface breaking defects.
  • Can easily be combined with other methods with minimal added inspection time.

Limitations of VT

  • Typically, human based, with reliability highly dependent on inspector training and skill level.
  • Can detect only volumetric surface breaking defects.
  • Cannot reliably detect small flaws.
  • When human based cannot reliably detect flaws at mass production volumes.

Components can be screened for a variety of functional characteristics either prior to or after NDT examination to suit your company’s needs. Evaluation of fit to mating parts, proof load, operating characteristics and other characteristics can be conducted in-line with NDT in a bespoke inspection system, or they can be applied in a standalone, secondary process.

Cleaning & Finishing

Non-Destructive Testing auto parts

Pass Through Cleaning

Advanced Material Solution’s high speed pass through cleaning systems feature a 3-stage conveyor based approach to cleaning that washes, rinses and dries parts, leaving them ready for packaging. Both the wash and rinse stages utilize customized nozzle designs that spray parts from above, below and from the side to ensure effective cleaning of both interior and exterior part surfaces. When needed, cleaning can be performed in combination with a variety of NDT testing techniques, for example, ultrasonic or eddy current testing.

Immersion Cleaning

Advanced Material Solution’s fully automated 4-stage immersion washing systems are designed for high volume precision cleaning, rinsing, and drying of components in batch quantities. We rapidly process components in a continuous feed system that simultaneously processes and transfers multiple baskets. The consistency delivered by the automation enhances part cleanliness and quality, and reduces failures down the assembly/test line. The steps are PLC controlled with dual phases within the precision washing and rinsing stages, sequencing powerful ultrasonics with turbo/agitation.

The ultrasonic system combines powerful sweep frequency ultrasonics with turbo/filter/agitation washing. Using mechanical agitation washing to remove gross contamination and ultrasonic cleaning to remove finer and/or more resistive deposits is a most effective processing routine.

Top Coat Application

In addition to cleaning, Advanced Material Solution’s automated and manual metal finishing work centers can be used to apply top coat to your specifications to address lubricity, corrosion resistance and rust prevention.

Flash Rust Removal

Seasonal flash rust can be a nagging problem, interfering with your normal plant operations, risking component safety. Additionally, scrap costs and lost production can be minimized.

Advanced Material Solution’s automated and manual metal finishing work centers can be used to remove flash rust and return parts to proper conditions, suitable for assembly.

Rust Preventative Application

Advanced Material Solution’s automated and manual parts cleaning processes include the application of rust preventative to provide protection from rust during transport. And for those cases where our cleaning services aren’t needed, the processes can be designed to simply apply the rust preventative, dry and pack.
