Abstract

The possibilities of the radioscopic detection of defects such as remnant joint lines, which occur during friction stir welding, have been evaluated. In addition to common radioscopy, a microfocus source of X-ray radiation and metallography were applied to attain high geometric magnification. It was shown that this defect type can be detected using high geometric magnification; defects such as foreign inclusions may occur as a result of tool wear.
