The couplant used should not be injurious to the material to be examined, should form a thin? Amplitude shall be digitized at a resolution of at least 8-bit that is, levels. For thin sections, it may be possible to use a single stand-off position with either E-scans or S-scans.

Surface notches may be used under some circumstances but are not generally recommended. The modeled e2070 in the upper portion of Fig. The values given in parentheses are for information only. 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.
The practice is intended to be used on thicknesses of 9 to mm 0. For improved sizing capabilities techniques described in Guide E may be more suitable and can be adapted to phased array applications. NOTE—Butt welds should be examined from both sides of the weld and preferably from the bevel opening side when access permits.
When glycerin is used, a aetm amount of wetting agent is often added, to improve the coupling properties. Use is made e22700 all re? Alternative scanning techniques shall be used for different weld pro?
Examination from both surfaces of the web-plate plate should be used when access permits. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not sstm standard. 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. S-scans have the advantage over E-scans that all the speci?
This practice provides procedural guidance for both manual and mechanized scanning of welds using phased aztm systems. The system shall be capable of generating and displaying both B-scan and S-scan images, which can be stored and recalled for subsequent review.

Set the signal from the reference re? For double Vee welds, angle beam examinations should be carried out from both e700 when access permits. Note 1—This practice is based on experience with ferrous and aluminum alloys.
E — 09 7. 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 e2700. The values given in parentheses are for information only. 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.
Phased array probes may be used with a removable or integral wedge, delay-line, or in an immersion or localized bubbler system mode. Probe placement will be de? Where scanning is to be performed along the top or across this weld, the weld e27000 may be ground to provide a?
