The values given in parentheses are for information only. An external storage device,?
Apply the correction to all focal laws used for the examination. If laterally focused beams are used, this can be considered for data collection increments as above. Greater and lesser thicknesses may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry. Range standardization shall include correction for wedge travel time so that the zero-depth position in the test piece is accurately indicated for each focal law.
For certain combinations of thin wall and small diameter pipe side drilled holes may not be practical and surface zstm may be used with agreement between contracting parties.
For improved sizing capabilities techniques described in Guide E may be more suitable and can be adapted to phased array applications.
Only 1D arrays or dual arrays con? The preferred probe placement for the angle beam is on the surface where the weld bevel opening occurs.
Since acceptance criteria are not sstm Greater and lesser thicknesses may be tested ee2700 this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry.
BoxArlingate Ln. Some phasedarray systems may include options for entering some items into a report format and incorporating S-scan or B-scan images as part of the report.
With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Examination from both sides of the web plate should be used when access permits. The modeled coverage in the upper portion of Fig.
Alternative welding techniques, such as solid state bonding for example, friction stir welding and fusion welding for example, electron beam welding can be inspected using this practice provided adequate coverage and techniques are documented and approved. The practice is intended to be used on thicknesses of 9 to mm 0. This practice provides procedural guidance for both manual and mechanized scanning of welds using phased array systems.
Practices for specific geometries such as spot welds are not included. A remote portable PC connected to the instrument may also be used for this purpose. For 2D arrays, which use electronic oscillation, calibration should be performed at all skewed angles. A number in parentheses indicates the year of last reapproval. Inhibitors or wetting agents, or both, may be used.
Where scanning is to be performed along the top or across this weld, the weld reinforcement may be ground to provide a?
This target may be considered the primary reference re? The technique used will depend on whether or not the weld reinforcement has been ground? Greater and lesser thicknesses may be tested using this standard practice if the technique can be demonstrated to provide adequate detection on mockups of the same wall thickness and geometry 1.
Link to Active This link will always route to the current Active version of the standard. SE provides details to be considered in the procedures used. Your comments are invited either for revision of this standard or for additional standards and should be addressed xstm ASTM International Headquarters.
Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements.
The practice is intended to be used on thicknesses asstm 9 to mm 0. Data, in the form of A-scans from each focal law used, shall be collected at increments of not greater than 2 mm with at least three increments for the length of the smallest required detectable defect, that is, a defect length of 3 mm would require increments of not greater than 1 mm along the scan axis.
The test equipment, probe sfocal law scouplant, etc. Welds shall be inspected from both sides, where possible.
NOTE—Butt welds should be examined from both sides of the weld and preferably from the bevel opening side w2700 access permits. This method can be used only if the instrument is provided with electronic distance amplitude compensation circuitry TCG. Guide mechanisms such as probe holding frames or magnetic strips are used to ensure that the probe moves at a?

e27000 If instruments do not inherently store A-scan data, such as some manual instruments, the? For thin wall sections, a single probe stand-off may be possible for linear scanning if the probe parameters are adequate for full volume coverage.
This practice is based on experience with ferrous and aluminum alloys.
