Internal and external counterbore slopes around a parametric weld in CIVA UT

 

Parametric definition of counterbore slopes around a weld

 

For the specimen profile to be valid, it is necessary to respect the construction constraint of a welded metal thickness smaller than the base metal thickness. The addition of counterbore slopes (symmetrical or not on either side of the weld) is compatible in planar and cylindrical weld configurations, thus allowing the construction of plate, tube, tube and elbow junction. This new CIVA functionality then allows the evaluation of the sensitivity of a UT inspection process to variations in slopes around a weld in the context of parametric studies!
