Automated Inspection using X-ray Imaging

With increasing concern on environmental contamination due to pipeline leak, the electronics industry is coming under increasing pressure to develop and apply automated inspection techniques for the inspection of welding line of steel tubes and structural casting. Automatic X-ray inspection systems are taking the high cost out of production inspection for casting manufacturers who previously relied on manual inspection methods while simultaneously wiping out the drudgery and potential for human error common to manual inspection methods in processing and manufacturing applications. Based on the analysis of basics of X-ray Imaging Principle, the interactive process of automatic X-ray inspection was discussed and a new defect inspection method using tophat operator was put forward. Lastly, this method is applied for many samples of X-ray images, and proved to be effective.
