ASTM E 164 - 97. Standard Practice for Ultrasonic Contact Examination of Weldments

American Society for Testing and Materials (ASTM), 1997, 23 pages.
This practice covers techniques for the ultrasonic A-scan examination of specific weld configurations joining wrought ferrous or aluminum alloy materials to detect weld discontinuities (Note 1). The reflection method using pulsed waves is specified. Manual techniques are described employing contact of the search unit through a couplant film or water column.
This practice utilizes angle beams or straight beams, or both, depending upon the specific weld configurations. Practices for special geometries such as fillet welds and spot welds
are not included. The practice is intended to be used on thicknesses of 0.250 to 8 in. (6.4 to 203 mm).
