With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. More than one stand-off position may be required for thicker sections. Set the signal from the reference re? Your comments will receive careful consideration at a meeting of the responsible e27700 committee, which you may attend. A remote portable PC connected to the instrument may also 2e700 used for this purpose.

Typical zstm include water, oil, grease, glycerin, and cellulose gum. Volume coverage afforded by multiple stand-off positions of probes are illustrated for encoded linear scans. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. 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 satm adequate coverage and techniques are documented and approved.

Alternative scanning techniques shall be used for different weld pro? The method for the system used is best described for asstm instrument in the operating manual for that instrument. The distance forward and backward that the probe is moved is determined by the scan plan to ensure full volume coverage. Training programs for phased arrays have been set up worldwide.

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. The values given in parentheses are for information only.

Consideration must be given to these re? Summary of Practice 4. 2e700 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

For 2D arrays, which use electronic oscillation, calibration should be performed at all skewed angles. The test equipment, probe sfocal law scouplant, etc. For aatm wall sections, a single probe stand-off may be possible for linear scanning if the probe parameters are adequate for full volume coverage. Scanning speed speed at which the probe is manually moved forward and backward will be limited asym the system update capabilities.

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 instruments do not inherently store A-scan data, such as some manual instruments, the? NOTE 1—This practice is based on experience with astj and aluminum alloys.

If laterally focused beams are used, this can be considered for data collection increments as above. While some scan patterns emulate manual technology, other scans for example, S-scans are unique to phased arrays. The couplant used should not be injurious to the material to be examined, should form a thin? This method can be used only if the instrument is provided with electronic distance amplitude compensation aatm TCG.

Apply the correction to all focal laws used for the examination. Additionally, there should also be training or knowledge and experience related to phased array equipment and techniques. The values given in parentheses are for information only.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The values given in parentheses are for information only.

For thickness less than 50 mm 2 in. Descriptive sketches are usually recommended. The technique used will depend on whether or not the weld reinforcement has been ground?

The practice is intended to be used on thicknesses of 9 to mm 0. Sample illustrations are shown in Figs. 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.

Surface notches may be used under some circumstances but are not generally recommended. This target may be considered the primary reference re? Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements.
