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 modeled coverage in the upper portion of Fig. NOTE 1—This practice is based on experience with ferrous and aluminum alloys.
ASTM E2700-14 Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays
Surface notches may be used under some circumstances but are not generally recommended. In some cases a phased array probe may be used without xstm refracting wedge or delay-line that is, just e2700 hard wear-face surface.
An external storage device,? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is important to produce a surface that is as?
ASTM E2700 – 14
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. Link to Active This link will always route to the current Active version of the standard.
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.
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. If this is the case, drill another hole at 1? Alternative scanning techniques shall be used for different weld pro? 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.
With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. Therefore, it is necessary that the display used provide a uniform color code related to amplitude at all sound path distances. Set the signal from the reference re? This target may be considered the primary reference re? Where scanning is to be performed along the top or across this weld, the weld reinforcement may be ground to provide a? Basis of Application 6.
For special applications, frequencies up to 20 MHz can be used, but may require special instrumentation with appropriate digitization, and special approval. This may include the following information: The distance forward and backward that the probe is moved is determined by the scan plan to ensure full volume coverage. Current edition approved Aug.
Sensitivity amplitude reference standards that accomplish this are e27000 holes parallel to the major surfaces of the plate and perpendicular to the sound path,? Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements. Welds shall be inspected from both sides, where possible.
For 2D arrays, which ee2700 electronic oscillation, calibration should be performed at all skewed angles. Practices for specific geometries such as spot welds are not included. Personnel performing examinations to this standard should list the qualifying credentials in the examination report. If the source of sensitivity change is a result of change in the number of asfm elements compared to the baseline assessment it may require probe replacement.
Note 1—This practice is based on experience with ferrous and aluminum alloys.
Probe placement will be de? Use is made of all re? Ast, preferred probe placement for the angle aetm is on the surface where the weld bevel opening occurs.
The practice or standard used and its applicable revision shall be identi? A remote portable PC connected to the instrument may also be used for this purpose.
The lateral movement on each raster step shall not exceed half the element dimension in the lateral direction.
BoxArlingate Ln. The test equipment, probe sfocal law scouplant, etc. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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. Alternative welding techniques, such as solid state bonding for example, friction stir welding and fusion welding for example, electron beam welding e27700 be inspected using this practice provided adequate coverage and techniques are documented and approved.
This method is suitable for large planar? 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.
Note that this interval should be reduced when length sizing of? Practice E covers setting up of phased arrays for weld inspections.
