Hardness Testing Basics.  Hardness is a characteristic of a material, not a fundamental physical property.  It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.

What we do

Hardness Tests are extensively used to characterize a certain material, and to identify if it is appropriate for its intended purpose.  All Hardness Tests involve the utilization of a particularly shaped indenter that is harder than the material under testing.  The indenter is pressed onto the test surface with the use of a certain amount of force.  The size of the depth of the indent is measured in order to determine the hardness value.

Benefits of Hardness tests:

• The Hardness Test is easy to conduct
• Results can be obtained within 30 seconds
• Tests are relatively cost-effective
• Finished components can be subjected to testing without being damaged
• Any shape and surface size can be subjected to testing

The major applications of Hardness Tests are to verify the type of heat treatment to be used on a part, and to identify if a material possesses the required properties for it’s intended use.  This makes Hardness Tests beneficial in industrial applications.

The five most common hardness scales are:

• Knoop
• Vickers
• Rockwell
• Brinell
• Shore

Most popular Questions

What is Brinell’s hardness test?

Brinell Hardness (BH) Test.  Method of measuring the hardness of a material by pressing a chromium-steel, or tungsten-carbide ball (commonly one centimeter or 0.4 inch in diameter) against the smooth material surface, under standard test conditions (generally between 300 to 3 000 kilograms of force for 5 to 30 seconds).

What is hardness testing?

Hardness is a characteristic of a material, not a fundamental physical property.  It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.  The Rockwell Test is generally easier to perform, and more accurate than other types of Hardness Testing Methods.

How do hardness testers work?

A Hardness Test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing.  The hardness is determined by measuring the depth of indenter penetration, or by measuring the size of the impression left by an indenter.

Measuring the amplitude of the reflected signal is a relatively unreliable method of sizing defects because the amplitude strongly depends on the orientation of the crack. Instead of amplitude, TOFD uses the time of flight of an ultrasonic pulse to determine the position and size of a reflector.                                       

What we do

ToFD is an ultrasonic technique originally developed for crack detection. Unlike conventional Pulse Echo, the transmitter receiver in arrangement in ToFD floods the region between the probes with ultrasound. Crack tips are identified by diffraction but it is also very effective for the detection and sizing of Weld Root Erosion or Corrosion (WRE or WRC)

The nature of the reflection of the ultrasound from eroded/corroded areas in the TFD pitch-catch arrangement makes it ideal for the detection of Weld Root Erosion/Corrosion. This approach has a proven track record as an accurate method for the detection and monitoring of corrosion and erosion damage in the weld and heat affected zones.

Most popular Questions

What is Tofd inspection?

TOFD offers rapid weld inspection with excellent flaw detection and sizing capacities. The diffraction technique provides critical sizing capability with relative indifference to bevel angle or flaw orientation. TOFD can be utilized on its own or in conjunction with other NDT techniques.

What does TOFD stand for?

Time-of-flight diffraction (TOFD) method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington in 1975 which paved the way for TOFD.

(PA) is an advanced method of Ultrasonic Testing that has applications in Medical Imaging and Industrial Non-Destructive Testing.  Common applications are to non-invasively examine the heart or to find flaws in manufactured materials such as welds.

What we do

Ultrasonic Phased Arrays use a multiple element probe, whereby the output pulse from each element is time delayed in such a way, as to produce constructive interference at a specific angle and a specific depth.  These time delays can be incremented over a range of pre-defined angles to sweep the beam inside the area of inspection.  Due to the possibility to control parameters, such as beam angle and focal distance; this method is very efficient regarding the defect detection and speed of testing.  Apart from detecting discontinuities in welds and components, Phased Arrays can also be used for, Thickness Measurements and Corrosion Inspection

Our Technicians design and developed their own scanners to ensure that the inspections cover all the requirement and for accurate repeatability of defect monitoring.

Most Popular Questions

Why is radiography test required?

Radiographic and Ultrasonic Weld Inspections are the two most common methods of Non-Destructive Testing (NDT) used to detect discontinuities within the internal structure of welds.  Energy not absorbed by the object, will cause exposure of the Radiographic Film.  These areas will appear dark when the film is developed.

How do X rays differ from gamma rays?

X-Rays and Gamma Rays differ only in their source of origin.  X-Rays are produced by an X-Ray Generator and Gamma Radiation is the product of Radioactive Atoms.  They are both part of the Electromagnetic Spectrum.  They are waveforms, as are light rays, microwaves, and radio waves.

How is radiography done?

Industrial Radiography 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.  Industrial Radiography can be performed utilizing either X-Rays or Gamma Rays.

Most Popular Questions

What is the principle of liquid penetrant testing?

The principle of Liquid Penetrant Testing is that the liquid penetrant is drawn into the surface-breaking crack, by capillary action and excess surface penetrant is then removed;  a developer (typically a dry powder) is then applied to the surface, to draw out the penetrant in the crack, which produce a surface indication.

Which type of penetrant is most sensitive?

Fluorescent Penetrant systems are more sensitive than visible penetrant systems, because the eye is drawn to the glow of the Fluorescing Indication.

Which type of developer is considered the most sensitive?

Non-aqueous developers are generally recognized as the most sensitive when properly applied.  There is less agreement on the performance of dry and aqueous wet developers, although the aqueous developers are usually considered more sensitive.

Most Popular Questions

What is MPT test?

Magnetic Particle Testing (MPT), also referred to as Magnetic Particle Inspection, is a non-destructive examination (NDE) Technique used to detect surface and slightly sub-surface flaws in most ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys

Can you magnetic particle inspect stainless steel?

It is true that you can perform Magnetic Particle Testing on Ferritic Stainless Steel.  The easiest method of determining if the material can be Magnetic Particle Inspected is to see if a Permanent Magnet is attracted to the material.  The three elements which are Ferromagnetic:   Iron, Nickel and Cobalt.

What is the basic principle of magnetic particle testing?

In theory, Magnetic Particle Inspection (MPI) is a relatively simple concept.  It can be considered as a combination of two Non-Destructive Testing methods:  Magnetic Flux Leakage Testing and Visual Testing.  Consider the case of a bar magnet, it has a magnetic field in, and around the magnet.
