The NDTs (Non Destructive Examinations) are a historic milestone during the Quality Control of base materials and welded joints. In the Italian Institute of Welding Group's Laboratory, conventional and advanced Non Destructive Examinations are available for integrating more complex analyzes (suc as in case of the Failure Analysis) and for evaluating the quality level of welded coupons before the mechanical testing (such as in case of the Qualification of Welders or the Qualification of Welding Procedures).
Moreover, we can also carry out NDTs for evaluating the compliance of base materials or welded joints with predetermined quality levels, on the basis of the Client applicable acceptance criteria or specifications.
In the Italian Institute of Welding Group's Laboratory the following methods are available:
- Visual Examination (VT)
- Ultrasonic Test (UT)
- Advanced Techniques Ultrasonic Test (AUT)
- Film or Computer Radiographic Examination (RT)
- Magnetic Particle Examination (MT)
- Dye Penetrant Examination (PT)
- Leak Testing (LT)
The NDTs are usually performed in accordance with the EN ISO International Standards or with the ASME BPV Section V requirements; other Client Standard or Specifications can be applied on request.
The Laboratory staff executing the NDTs is qualified and certified in accordance with the Standard EN ISO 9712 and / or the ASNT Recommendation SNT-TC-1A.
