ULTRASONIC WELD ANALYSIS FOR ORTHOTROPIC STEEL DECKING SYSTEMS IN BRIDGES

摘要

A system provides for the calculation of the penetration depth of a weld inan orthotropic steel decking system. Weld scan section data is accessed andeachscan section along the weld seam is processed to find the amount ofpenetrationas a percentage of the thickness of the rib leg metal at the weld location.Theamount of penetration is calculated by finding ultrasonic reflections recordedasvoxels that have the greatest magnitude within an area of contiguousmagnitudesand then determining the location of those voxels relative to the weldgeometryand distance along the thickness of the rib leg steel. A report for eachsectionscan and the entire weld seam may be generated for review by a weld inspectorthat allows for spot inspections of specified areas along the weld seam forpossible weld remediation.
