The distance forward and backward that the probe is moved is determined by the scan plan to ensure full volume coverage. Practice E recommends methods of assessing performance characteristics of phased array probes and systems. Greater aetm 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.
This target may be considered the primary reference re? Link to Active This link will always route to the current Active version of the standard. In some cases a phased array probe may be used without a refracting wedge or delay-line that is, just a hard wear-face surface.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
In manual scanning, the dominant display will be an S-scan with associated A-scans. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
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 values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Alternative scanning techniques shall be used for different 2e700 pro?
Where scanning is to be performed along the top or across this weld, the weld reinforcement astmm be ground to provide a?
Sensitivity amplitude reference standards that accomplish this are sidedrilled holes parallel to the major surfaces of the plate and perpendicular asgm the sound path,? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
For thin sections, it may be possible to use a single stand-off position with either E-scans or S-scans. In addition, the alternative method and its equipment shall meet all the performance requirements of this standard. Phased array probes may be used with a removable or integral wedge, delay-line, or in an immersion or localized bubbler system mode. 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.
Only 1D arrays or dual arrays con? AIAWilson Blvd. 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.
The values given in parentheses are ashm conversions to SI units that are provided for information only and are not considered standard. Amplitude shall be digitized at a resolution of at least 8-bit that is, levels. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. For thick wall sections, multiple probe stand-offs or multiple focal law stand-offs will be required for linear scanning to ensure full volume coverage.
Examination from both sides of the web plate should be used when access permits. 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 aetm by an ultrasonic beam. The applicable edition of Practice E shall be speci?
Apply the correction to all focal laws used for the examination. Therefore, it is necessary that the display used provide a uniform color code related to amplitude at all sound path distances.
An external storage device,? This standard is subject to revision at any time by the ast technical committee and must be reviewed every? The practice or standard used and its applicable revision shall be identi?
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 e22700 and approved.
For 2D arrays, which use electronic oscillation, calibration should be performed at all skewed angles. Use is made of all re?
Scanning speed speed at which the probe is manually moved forward and backward will be limited by the system update capabilities. This practice is based on experience with ferrous and aluminum alloys. The lateral movement on each raster step shall not exceed half the element dimension in the lateral direction.
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.
S-scans have the advantage over E-scans that all the specified inspection angles can be covered at the same time. For additional pertinent information, see Practices EEand E 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.
If this is the case, drill another hole at 1? When glycerin aetm used, a small amount of wetting agent is often added, to improve the coupling properties. Note 1—This practice is based on experience with ferrous and aluminum alloys.
When water is used, it should be clean and de-aerated if possible.
