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

It is now possible in CIVA UT to parametrically define counterbore / skidding slopes on internal and external walls around a weld. To do this, simply define a “Weld” geometry type in the “Specimen” panel, and activate the slopes in the ‘”imensions > Thickness, counterbore > Skidding > With skidding” panel. You must then define a length and an angle for each slope (single slope on external wall and double slopes on internal wall).

 

 

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!
