Ultrasonic testing is a non-destructive testing method that is used commonly for -        Detecting cracks, defects and faults in a test piece; -        Measuring the dimensions of a test piece; -        Understanding the nature or character of a material; How is the test carried out? The testing unit or system consists of a receiver, transducer, and a display unit. The receiver or pulse is the unit that produces electrical pulses. The transducer then produces ultrasonic energy in high frequency. This sound energy or wave passes through the test piece. If the material has no-fault, it will behave as a standard piece – however, when there is a crack, fault, or break in between, the wave is intercepted by this fault line from where the wave reflects. This reflected wave or echo is then converted by the transducer into an electrical signal. This electrical signal gets displayed on the screen. The duration or period from wave generation to the echo is now displayed on the sc

UV light torches are used for typically seeing things that are invisible to the normal eyes. From detecting rodents in warehouses to detecting forgery with currency notes, from identification of oil leakages to detecting gemstone and minerals, arson detection, inspection of crime scenes and artwork, there are multiple uses of UV lights. These are some of innovative features of UV torch lights : ●    The wavelength of UV light is measured in nm or nanometers . ●    UV lights of only specific wavelengths can induce enough fluorescence – an aspect that is the most important feature that most applications of the UV torch light uses. ●    UV light that is around the range of 360 nm has the most forceful fluorescent glow. ●    The watts or power of the UV torch light will indicate the strength of the light. ●   UV torch lights can be powered by AA or AAA battery cells. These torches are good for occasional use. ●     UV torch lights that need to run for a longer time s

Eddy current testing or electromagnetic testing is based on the science of electric current being induced in conductors when the magnetic field around them changes. This flow of eddy current with changing magnetic field finds application in locating and sizing minute cracks and defects existing on the surface, can estimate the thickness of coatings, and can assist in determine the material make up (i.e. alloy) a test element. The current is characterised by closed loops that start to make a magnetic field of their own. As a result, the magnetic field produced by the eddy current and the initial magnetic field opposes each other. The eddy current produced by a material in its pure form will differ from the eddy current produced by the material when present in an altered or defect form. This difference in the creation of a magnetic field is what gets primarily used for NDT or non-destructive testing of materials. How the process works? In order to produce eddy current, alt

Portable hardness testers help perform hardness testing on-site or in-situ. This form of testing is required for two reasons – to confirm that the test piece meets required specifications and to check the quality of a new sample test piece. There are different known methods of conducting portable hardness test . However, before choosing a particular method over another, these parameters of the material and the process needs to be considered thoroughly: The material type of the sample that is being tested. If there is an approximate value of the hardness of the material? Whether the material is homogeneous or heterogeneous? What is the size of the material being tested? Does the testing result need to be compliant with a specific standard? How accurate the testing result needs to be? What are the number of samples that need to be tested? Whether the test piece needs to be mounted or not for carrying out the test? Other factors

It’s safe to say we are in the midst of a technological revolution. The fourth industrial revolution or Industry 4.0 as it is also known, is rapidly transforming the way businesses operate. Even NDT hasn’t been able to escape the advances in automation, “Internet of Things”, artificial intelligence, sensor technology, big data and analytics. Industry 4.0 promises to revolutionise business models and outcomes, meaning that the NDT we see today will likely not be the same as the NDT we see in the next decade. NDT and the Cloud  NDT goes where the work is. In Australia that often means onto remote sites both inland and offshore. Quality control and collaboration become difficult when colleagues are thousands of kilometres apart. NDT technology that utilises cloud storage provides a unique solution to a problem that grows with an increase in workload and distance. One example of the integration of cloud storage into NDT is the Logbook used by Proceq’s live series of equipment. Ev

Non-destructive testing methods are cost-effective and will enable you to save a lot of time, money, and effort in getting the results you need to make informed decisions about your project. One of these is the dye penetrant inspection (DPI) or dye penetrant test, which is specifically used to identify surface breaking flaws. Sometimes referred to as, ‘liquid penetrant inspection’ (LPI), this method can assist in detecting cracks, seams, laps, porosity, and other kinds of surface breaking voids. This inspection method can be used on non-porous materials both ferrous and non-ferrous, which includes materials such as ceramics, metals, and plastics. Dye Penetrant inspection is often used to find defects in welded joints, forgings, and castings. It is applicable to multiple industries, including aerospace, petrochemical, and power generation. Provided you have the correct equipment, and follow approved and consistent procedures, inspections can be conducted on-site or in remote areas
