This technique is not generally considered to be as effective as the technique described in Fig. It is important to produce a surface that is as? 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. In addition, the alternative method and its equipment shall meet all the performance requirements of this standard. For improved sizing capabilities techniques described in Guide E may s2700 more suitable and can be adapted to phased array applications.
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? 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.

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 thin sections, it may be possible to use a single stand-off position with either E-scans or S-scans. Note the amplitude responses from the side drilled holes is the same for each hole even though the angle used to detect the hole and the sound path to the hole is different in each instance.
Summary of Practice 4. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The practice is intended to be used on thicknesses of 9 to mm 0. When water is used, it should be clean and de-aerated if possible. If the equipment has changed by more than the agreed upon tolerances, it shall be re-standardized. 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.
For special applications, frequencies up to 20 MHz can be used, but may require special instrumentation with appropriate digitization, and special approval. Sample illustrations are shown in Figs. This method can be used only if the instrument is provided with electronic distance amplitude compensation circuitry TCG.
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.

Consideration must be given to these re? Training programs for phased arrays have been set up worldwide. This method is suitable for large planar? The method for the system used is best described for each instrument in the operating manual for that instrument.
Set the signal from the reference re? 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. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice.
The values given in parentheses are for information only. Basis of Application 6. S-scans have the advantage over E-scans that all the speci? A remote portable PC connected to the instrument may also be used for this purpose.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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. 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.
Additionally, there should also be training or knowledge and experience related to phased array equipment and techniques. The lateral movement on each raster step shall not exceed half the element dimension in the lateral direction. Examination procedures recommended for common weld con?
