If the equipment has changed by more than the agreed upon tolerances, it shall be re-standardized. Alternative scanning techniques shall be used for different weld pro? The test equipment, probe sfocal law scouplant, etc.

For double Vee welds, angle beam examinations should be carried out from both surfaces when access permits. Scanning speed speed at which the probe is manually moved forward and backward will be limited by the system update capabilities.

Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can e2070 successfully penetrated by an ultrasonic beam.

Apply the correction to all focal laws used for the examination. Active view current version of standard.

This technique is not generally considered to be as effective as the technique described in Fig. Consideration must be given to these re? For improved sizing capabilities techniques described in Guide E may be more suitable and can be adapted to phased array applications. The values given in parentheses are mathematical conversions to SI units that are provided for information only atsm are not considered standard.


Where scanning is to be performed along the top or across this weld, the weld reinforcement may be ground to provide a? 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 s2700 is different in each instance. W2700 remote portable PC connected to the instrument may also be used for this purpose.

Not all possible con? For thick wall sections, multiple probe stand-offs or multiple focal law stand-offs will be required for linear scanning to ensure full volume coverage. In manual scanning, the dominant display will be an S-scan with associated A-scans.

An ast storage device,? It is important to produce a surface that is as? The preferred probe placement for the angle beam is on the surface where the weld bevel opening occurs.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This may include the following information: Summary of Practice 4. NOTE—Butt welds should be examined from both sides of the weld and preferably from the bevel opening side when access permits. Sensitivity amplitude reference standards that accomplish this are sidedrilled holes parallel to the major surfaces of the plate and perpendicular to the sound path,?

Therefore, it is necessary that the display used provide a uniform color code qstm to amplitude at all sound path distances. Personnel performing examinations to this standard should list the qualifying credentials in the examination report. The technique used will depend on whether or not the weld reinforcement has been ground? Alternative welding techniques, such as solid state bonding for ast, 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.

This practice provides procedural guidance for both manual and mechanized scanning of welds using phased array systems. Historical Version s – view previous versions of standard. For thin sections, it may be possible to use a single stand-off position with either E-scans or S-scans.

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?

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. Commercial software permits the operator to easily make set ups without detailed knowledge of the phasing requirements.
