    unfortunately I’m not aware of any field portable equipment with these capabilities but would also be interested in seeing this functionality being implemented.

    As you seem to have quite extensive experience with TCMP steel: What would be your approach for calibration when checking welds in a sheet steel construction? For welds in rolling direction and transverse to the rolling direction its manageable as you mentioned. But there are also all the angles in between, sometimes even within one weld, for example with a circular part in a cutout.
    Our approach so far is to calibrate for one speed and for the highest losses of amplitude and if indications are found, we recalibrate for that specific area of interest and reevaluate.
