The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Practice E covers setting up of phased arrays for weld inspections.
The values given in parentheses are for information only. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Set the signal from the reference re? S-scans have the advantage over E-scans that all the specified inspection angles can be covered at the same time. The practice is intended to be used on thicknesses of 9 to mm 0.
atsm An external storage device,? 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.
SE provides details to be considered in the procedures used. With their distinct features and capabilities, phased arrays require special set-ups and standardization, as addressed by this practice. Surface notches may be used under some circumstances but are not generally recommended. More than one stand-off position may be required for thicker sections.
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. BoxArlingate Ln. Use is made of all re? S-scans have the advantage over E-scans that all the speci? Historical Version s – view previous versions of standard.
Practices for specific geometries such as spot welds are not included. Sample illustrations are shown in Figs. Active view current version of standard.
Examination from both surfaces of the web-plate plate should be used when access permits. Only 1D arrays or dual arrays con? A remote astmm PC connected to the instrument may also be used for this purpose. The practice or standard used and its applicable revision shall be identi? For e2700 wall sections, multiple probe stand-offs or multiple focal law stand-offs will be required for linear scanning to ensure full volume coverage.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. A general standard practice document is required to de? For improved sizing capabilities techniques described in Guide E may be more suitable and can be adapted to phased array applications. Scanning speed speed at which the probe is manually moved forward and backward will be limited aatm the system update capabilities.
Summary of Practice 4.
For special applications, frequencies up to 20 MHz can be used, but may require special instrumentation with appropriate digitization, and special approval. Sensitivity amplitude reference standards that accomplish this are sidedrilled holes parallel to the major surfaces of the plate and perpendicular to the sound path,?
Probe placement will be de? Practice E recommends methods of assessing performance characteristics of phased array probes and systems. Inhibitors or wetting agents, or both, may be used. 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 can be inspected using this practice provided adequate coverage and techniques are documented and approved.
