Abstract: A quality assurance system includes an internet/wide area network interface configured to provide bidirectional communication with user terminals; a wireless interface configured to provide bidirectional communication with mobile user terminals; and a quality assurance database cooperatively coupled with a database manager. The data base manager is configured to populate the quality assurance database with identifications of individual ones of a plurality of construction project welders, weld inspectors and a plurality of weld data logs individual ones of which are associated with a specific welding operation of a construction project. Each weld data log is configured to store information that is at least descriptive of a welder, material used during the specific welding operation, specifics of a completed weld including at least weld location, weld type and weld dimensions, and information descriptive of a weld examination.
