Abstract: The x-ray imaging is one of the important non-destructive testing methods in the inspection of welding defect. The defect of welding joint can cause severe failure of the products, so the inspection of welding area is an essential issue in various industrial fields. We have studied the x-ray linear laminography system to imaging the welding defect. We investigated the effects of focal spot size and step interval on reconstructed images. The larger focal spot decreases the spatial resolution and smaller step interval reduces the noise of the image. Those parameters should be determined with considering of scanning time of welding sample.
