A number in parentheses indicates the year of last reapproval. Codes and code cases have been astj, or are being developed, to cover phased array weld inspection requirements by organizations such as ASME.
For 2D arrays, which use electronic oscillation, calibration should zstm performed at all skewed angles. If the source of sensitivity change is a result of change in the number of active elements compared to the baseline assessment it may require probe replacement.
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 that this interval should be reduced when length sizing of? The lateral movement on each raster step shall not exceed half the element dimension in the lateral direction. Typical couplants include water, oil, grease, glycerin, and cellulose gum. The test equipment, probe sfocal law scouplant, etc.

The couplant used should not be injurious to the material to be examined, should form a thin? Generally using more focal laws requires more processing time so e700 rates of the B-scan or S-scan displays are slower as more focal laws are used.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Xstm 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.
With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. This practice provides procedural guidance for both manual and mechanized scanning of welds using phased array systems. Historical Version s – view previous versions of standard.

S-scans have the advantage over E-scans that all the speci? While some scan patterns emulate manual technology, other scans for example, S-scans are unique to phased arrays.
The practice is intended to be used on thicknesses of 9 to mm 0.

For double Vee welds, angle beam examinations should be carried out from both surfaces when access permits. Use is made of all re?
While some scan patterns emulate manual technology, other scans for example, S-scans are unique to phased arrays. Therefore, it is necessary that the display used provide a uniform color code related to amplitude at all sound path distances. This feature will be used only for assessment 7 of data quality as the scan is progressing and may allow for one or more channels to be monitored.
ASTM E2700 – 14
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. Current edition approved Aug. Welds shall be inspected from both sides, where possible. The method for the system used is best described for each instrument in the operating manual for that instrument.
Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements. Practices for specific geometries such as spot welds are not included.
