ASTM E – 14 Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays

Typical couplants include water, oil, grease, glycerin, and cellulose gum. Historical Version s – view previous versions of 2e700. Training programs for phased arrays have been set up worldwide.

A number in parentheses indicates the year of last reapproval.

The system shall be capable of generating and displaying both B-scan and S-scan images, which can be stored and recalled for d2700 review. The distance forward and backward axtm the probe is moved is determined by the scan plan to ensure full volume coverage. If laterally focused beams are used, this can be considered for data collection increments as above.

Descriptive sketches are usually recommended. Scanning speed speed at which the probe is manually moved forward and backward will be limited by the system update capabilities. S-scans have the advantage over E-scans that all the speci?

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. For certain combinations of thin wall and small diameter pipe side drilled holes may not be practical and surface notches may be used with agreement between contracting parties.

Inhibitors or wetting agents, or both, may be used. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. The applicable edition of Practice E shall be speci? Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements.

BoxArlingate Ln. This method can be used only if the instrument is provided with electronic distance amplitude compensation circuitry TCG. In most cases, the surface from which the straight beam is used needs no further examination using angle beams. A remote portable PC connected to the instrument may also be used for this purpose.

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. Practices for specific geometries such as spot welds are not included. Phased array probes may be used with a removable or integral wedge, delay-line, or in an immersion or localized bubbler system mode.

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.
