Weld Inspection
Welds are commonly used to join two or more metal surfaces. Such welds are designed to meet a certain design criteria which is set out to meet a specified design code such as ASME V. These codes will specify the acceptable size of any defects that may occur in a weld during manufacture or in-service. Typical welding defects, lack of fusion of the weld to the base metal, cracks or porosity inside the weld, and variations in weld density, could cause a structure to break or a pipeline to rupture. Welds may be inspected using a variety of NDT techniques including ultrasonic testing and liquid penetrant/MPI testing.
The following Sonatest Flaw Detectors have built in software for the evaluation of defect indications in accordance with all standard inspection codes eg AWS D1.1, AVG/DGS, API 5UE, DAC Curves.
DAC Curves meet the requirements of EN1714, JIS & ASME standards.
The above specified on board software are user selectable options on the Sitescan D+ series units.
For advanced semi-automated weld inspections, phased array technology enables the imaging of defects with increased speed; meeting the above stated codes; the Veo 16:64 is the instrument of choice.
