Gazahn The indications to be investigated are: This is the fourth time the race has been held. Every verification is considered adequate ifthe drift noted stay smaller as k 2 dB. It is therefore applicable for all items having at least one element inCast steel and constituing one Part of a hydraulic machine. Sorry, your blog cannot share posts by email. We need your help!

In the absence of specification, the founder will usethe technique described in part 1. On this occasion, any useful information shouldbe transmitted to the party concerned. The surfaces should bewithout ondulations which could hinder the contact between the probe and the part.
The products used shall be of high sensitivity. QP followed by a number: The Operator manually shifts the probe by applying it on the surfaceto be inspected which is coveredwith couplant contact technique.
Acceptance of a non conformity by the Customer in no way discharges theFounder, the Manufacturer or the Designer from their respective responsibilities. Please ask for a confirmation of the amount required by email before sending any payment, by contacting jhecker uol. Surface preparation intensity depends on the need to reveal finer discontinuities.
These processes are not equivalent to each other with regard to: The methods of use are specified in the Quality Sheet. The probe is shifted along parallel lineswith recovering so as to examine the entire area successively. This document is available in the following versions: These criteria only apply to 4ndications to be confirmed, according to the present specification.
They may be undertaken by theManufacturer or the Designer after the approval ofthe Founder in accordance with the agreed and qualified welding procedure.
The race was organised with good security. As a reference, the above example contains 6 indications, all taken into consideration. T0 facilitate the control of large parts through local magnetization, the surfaces can be marked out in Squares in elementary areas using chalk.
This report will be submitted to the Designer. We are a non-profit group that run this website to share documents. It will be the responsibility ofthe issuer of Quality Sheets QS to clearly complete those sheets, so as to define without ambiguity the place of examination and consequently the state of advancement required for the various controls prescribed.
If the Designer so requires, a reportwith Sketch will be established andtransmitted to him. Table 2 gives the characteristic values: The repartition of the areas subject to the thickness of the part can be definedaccording to the legend 9.
The inspection will be made using aprobe with a separatetransmitter receiver of4 MHz wherever possible for thicknessesor 2 50 mm. Scratching, hammering, shot blasting which may dull the Casting surface and thus hinder the penetration the of dye, the dye penetrantinspection should be preceded by a grinding of the surfaces to be inspected.
You are commenting using your Facebook account. Summary The present specification comprises: Any other method may be applied after previous agreement.
DAC Metbod The adjustment of amplification and intensity is carried out on indications obtained from artificial reflectors cylindrical holeswith flat bottom of the reference blocks. Incaseof doubt supplementaryinvestigationsmust be carried out afterhaving modified the examination conditions improvement of the surfacecondition, modification of the conditions of magnetization, etc The decision to repair or to perform a radiographic inspection for confirmation is left to the Founder see technical specification UT Table 1 The surfaces shall be prepared according to acceptance criteria.
These blocks are made of Cast steel and presentthe acoustic characteristics which are similar to the material to be inspected. TOP Related Posts.
Mauhn But the track was very nice, clean and green. For inspection of parts of more than mm, one or severalextra blocks of defined thickness relativeto the Order are added to the basic Set. C Probes with separate transmitter and receiver SE type for longitudinalwave or angle probes for transverse wave. In this case each party will have to be aware of several Quality Sheets produced. These devices and their instrumentation, if any, must be verified periodically using modalities defined by the User. Cumulation of 2 neighbouring indications 1. During these adjustments the intensity must be maintained as low as possible, the height adjustment of the reference echoes is obtained only through the adjustment of amplification.

Kagagami The outline ofthe defect defines the surface S of this defect; the length of the defect is the largest dimensionof the whole defect. The magnetic powder spread over thearea should be made up of a fine coating by adequate meansduring magnetization. Every verification is considered adequate ifthe drift noted stay smaller as k 2 dB. The degree of the indication is expressed in equivalent diameter 1.
