In most cases, the surface from which the straight beam is used needs no further examination using angle beams. Personnel performing examinations to this standard should list the qualifying credentials in the examination report.

Other axtm materials can be examined using this practice provided reference standards can be developed that demonstrate that the e2700 material and weld can be successfully penetrated by an ultrasonic beam.

The values given in parentheses are for information only. It is important to produce a surface that is as? The modeled coverage in the upper portion of Fig.

The values given in parentheses are for information only. SE provides details to be considered in the procedures used.

ASTM E2700 – 14

More than one stand-off position may be required for thicker sections. 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.

Not all possible con? Examination from both surfaces of the web-plate plate should be used when access permits. Examination procedures recommended for common weld con? This practice provides procedural guidance for both manual and mechanized scanning of welds using phased array systems.

Generally using more focal laws requires more processing time so update rates of the B-scan or S-scan displays are slower as more focal laws are used. The method for the system used is best described for each instrument in the operating manual for that instrument. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Current edition approved Aug. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. 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.

Link to Active This link will always route to the current Active version of the standard. A remote portable PC connected to the instrument may also be used for this purpose.

Phased array probes e2700 be used with a removable or integral wedge, delay-line, or in an immersion or localized bubbler system mode. The distance forward and backward that the probe is moved is determined by the scan plan to ensure full volume coverage.

The technique used will e7200 on whether or not the weld reinforcement has been ground? 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. Set the signal from the reference re? Welds shall be inspected from both sides, where possible.

If this is the case, drill another hole at 1? When glycerin is used, a small amount of wetting agent is often added, to improve the coupling properties.

While some scan patterns emulate manual technology, other scans for example, S-scans are unique to phased arrays. 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. When water is used, it should be clean and de-aerated if possible.

Guide mechanisms such as probe holding frames or magnetic strips are used to ensure that the probe moves at a? The applicable edition of Practice E shall be speci?

The values given in parentheses are for information only. BoxArlingate Ln. 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 e27000 geometry 1. Apply the correction to all focal laws used for zstm examination. Users of this standard are s2700 advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

The practice or standard used and its applicable revision shall be identi? For double Vee welds, angle beam examinations should be carried out from both surfaces when access permits. The practice is intended to be used on thicknesses of 9 to mm 0. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice.

Typical couplants include water, oil, grease, glycerin, and cellulose gum. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. Use is made of all re? Therefore, it is necessary that the display used provide a uniform asgm code related to amplitude at all sound path distances.
