| Summary: | Scanning contact potentiometry (SCP) is used for defects detection and for determine the coordinates of the defects localized in welded joints. Studied samples are welded by manual arc welding of two halves austenitic steel 321H (Chromium-Nickel-titanium stainless Steel) dimension of each 200×110×13.5 mm. Thereafter welding, seam width is about 12 mm. Subsequently welded sample is inspected using X-ray radiographic testing system. In order to compare techniques capabilities, plotted potentiograms and weld radiograph are compared. Experimental outcomes prove that defects can be detected by SCP technique. SCP results are complied with mathematical signal analysis of defects. This method may substitute some destructive or nondestructive methods. |
