FIELD: physics.
SUBSTANCE: ultrasound shear oscillations are introduced and received. Oscillation source and receiver is moved along and across welded seam. Pour-like defects are detected and their size is determined. Distance from radiation source to revealed defects is measured. Defect depth and distance between defects are defined in the chain of defects in their depth allowing for diametre of the two greatest adjacent defects.
EFFECT: simple method of defining crystallographic texture.
