Non-destructive Testing of Duplex Welding Joints
This paper presents results of non-destructive examination of welding belt and the heat affected zone. The samples were made using sheets of duplex stainless steel, welded through the method of manual welding with coated electrode, by utilizing 4 types of electrodes. The specimens were subjected to different nondestructive examination methods in order to identify the defects, to establish new efficient procedures and to achieve high productivity in detection of defects appeared.
