ASTM E 164 Document Information:
Title
Standard Practice for Ultrasonic Contact Examination of Weldments
ASTM International
Publication Date:
Aug 10, 2003
Scope:
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].
NOTE 1 - This practice is based on experience with ferrous and
aluminum alloys. Other metallic
materials can be examined using this practice provided reference
standards can be developed that
demonstrate that the particular material and weld can be successfully
penetrated by an ultrasonic
beam.
NOTE 2 - For additional pertinent information see Practice E 317,
Terminology E 1316, and Practice
E 587.
Values stated in inch-pound units are to be regarded as the standard.
SI units are given for
information only.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
