Anotácia textu normy ASTM E273-15 :

This practice describes the general ultrasonic examination procedures for the detection of discontinuities in the weld and adjacent heat affected zones of welded pipe and tubing by scanning with relative motion between the search unit and pipe or tube. When contact or unfocused immersion search units are employed, this practice is intended for tubular products having specified outside diameters and wall thicknesses. And when properly focused immersion search units are employed, this practice may also be applied to material of smaller diameter and thinner wall. This practice does not establish acceptance criteria for this procedure. A pulsed ultrasonic angle beam shall be propagated in the wall of the pipe or tube by either the surface contact or immersion method. The weld line shall then be examined from both sides to ensure detection of imperfections with a shape or orientation that produces a preferential direction of reflection.
