This paper describes the application of the ACFM technique for weld inspection and focuses on recent experience in both Europe and Central America in the use of the technique for the inspection of steel storage tanks. Inspection of the tank floor is usually conducted using magnetic flux leakage methods but it is recognised that this cannot be applied to the detection of cracking in the welds jo...

Software development is constrained by time, cost and quality requirements. The problems of managing software projects have been well defined by the software engineering community. Software defects are one of the most influential factors affecting the success of a software project. Software inspection has become an essential solution for managing software defects. A variety of software inspecti...

Recently the industries provide visual inspection processes in the plants for keeping and guaranteeing product quality. Many visual inspection processes are normally operated by the manual visual inspection. The results of the manual visual inspection are often unstable because the results are depended on the inspection worker skill. Currently the automated visual inspection technologies are ge...

The measurement and inspection of manufactured parts play a vital role in manufacturing industry and is considered an integral part of the quality control. Though this is recognized, the state of the art in measurement and inspection of components is still recognized as a separate island of automation with no formal overall integration of standards and specifications. Although the introduction ...

Broken rails are the most frequent cause of freight-train derailments in the United States. Consequently, reducing their occurrence is a high priority for the rail industry and the U.S. Federal Railroad Administration. Current practice is to periodically inspect rails to detect defects using nondestructive technology such as ultrasonic inspection. Determining the optimal rail inspection frequen...

Nowadays, wood companies are ever more interested in automatic vision systems (Li & Wu, 2009), (Åstrand & Åström, 1994), for an effective surface inspection that greatly increases the quality of the end product (Smith, 2001), (Armingol et al., 2006). The inspection process, in most visual inspection systems, pursues online defects identification, to reach optimum performance (Malamas et al., 20...

Comprehensive and accurate inspections of welded components have become of increasing importance as NASA develops new hardware such as Ares rocket segments for future exploration missions. Simulation and modeling will play an increasing role in the future for nondestructive evaluation in order to better understand the physics of the inspection process, to prove or disprove the feasibility for a...

As a visual inspection system can’t meet all the testing demands of various types of piston assembly, a visual inspection reconfigurable model for piston assembly was designed. A five-layer gray box model was established based on analyzing the process of visual inspection, and expressed by extension element; On this basis, a foundation scheme library was made using extension transform and gener...
