NDT or Nondestructive Testing also known as Nondestructive inspection, is a group of techniques employed in science and technology industry to assess the properties of a component, material or system without causing any harm. It is considered to be a highly valuable method for testing as it does not change the particles of the material being inspected permanently thus, saving both money and time in evaluating products, troubleshooting and researching on them. There are different methods of advanced NDT inspection in Singapore and Malaysia that can be grouped under conventional and advanced. Under the conventional NDT methods ultrasonic, magnetic-particle, liquid penetrant, radiographic, eddy-current testing are included, while in advanced NDT other methods are included which are as follows:
- Computerized Radiography
- Rapid Gear Scan
- Phased Array Ultrasonic Testing (PAUT)
- Time of Flight Diffraction (ToFD)
- Automated and Remote Ultrasonic Testing
- Magnetic Flux Leakage
- IRIS (Internal Rotational Inspection System)Testing
- Alternative Current Field Measurement (ACFM)
- Guided Wave Ultrasonics
- Acoustic Pulse Reflectometry
Training and Certifications for Advanced NDT
People who wish to become a part of this testing industry can undergo training to receive certificates making them eligible to work in this particular domain. Training on conventional as well as advanced techniques are provided by various organizations which double up as academic institutes for aspiring professionals. Training is provided by BINDT accredited company and they are usually of high quality. The companies providing training are also authorized qualifying bodies for such work.
The training facilities are geared towards providing training on enhanced skills and knowledge of the candidates. It increases his/her experience and confidence as well. Experts in the field provide training to the students which is effective in producing efficient professionals later on. The training courses are not just geared towards passing the examination but also towards making the candidate a successful professional. One of the commonest courses in this field is the ASNT or PCN.
Benefits of Advanced Nondestructive Training
The biggest benefit of providing an advanced nondestructive training is that the inspected data is more accurate and reliable. Also, it comes with an improved PoD which makes the data available to repeat and record time and again. Methods like Phased Array Ultrasonic Testing or PAUT offers more intuitive displays and improved ways of data presentation. It also generates better inspection reports of higher value for clients. For instance, a color-coded C-scan is a brilliant way of representing inspection data. Different colors can be used for displaying different aspects like wall thickness using these advanced methods like PAUT. Some clients will find it easy to interpret the simple ECA C-Scan in comparison to a more complicated and conventional eddy current display.
Advanced nondestructive techniques are better for utilization in specific inspections as they provide greater control over equipment configuration. Optimizing the use of equipment is also easier with this technique. Advanced NDT techniques can help store large amounts of data as well.
The advanced NDT techniques with all these advantages and certified courses have become a strong craze among the aspiring professionals. These are more effective, reliable and hence used more in various technologically advanced industries for inspection or testing.
