NON-DESTRUCTIVE TESTING WELDING
TEC Eurolab
TEC Eurolab’s non-destructive testing service for welding evaluation and qualification
WHAT NON-DESTRUCTIVE TESTS OF THE WELDED PRODUCT CAN TEC EUROLAB CONDUCT?
In the welded product verification process, non-destructive testing is generally the starting point of the validation activity, as it does not involve permanent damage or modification of the structures being investigated.
TEC Eurolab can provide NDT inspection services in accordance with all major standardized methods
SUPERFICIAL METHODS
- Visual method – vt
- Liquid penetrant method – pt
- Magnetoscopic method -mt
VOLUMETRIC METHODS
- Radiographic method – RT
- Ultrasonic Method – UT
- Industrial computed tomography
allowing the customer to submit its welding process for qualification according to prior determined applicability ranges and validation criteria.
TEC Eurolab’s decades of know-how allow it to offer the optimal inspection strategy to the customer, selecting the best combination of inspection techniques and identifying the appropriate standards for the verification of the welded product related to the relevant industrial sector and indicating the best methodology for a correct execution of the examination.
