Abstract
This project was aimed at developing an automated weld inspection system
comprising image capture hardware and weld interpretation software for weld
quality inspection in various industries, such as oil and gas, power plants and
chemical processing plants. The quality of weld is determined from a radiograph
taken normally using gamma radiation. The radiographs are processed and
inspected manually by qualified weld inspectors. In a typtcal constnK.'1ion of a
plant, hundreds of radiographs must be inspected within a short duration. Manual
inspection is tedious, slow and very subjective. An automated weld inspection
system will overcome most of the problems retating to manual Inspection,
particularly speed and subjectivity of manual interpretation. This project was
proposed to develop such as system.
