Important Notice

Please read the following information prior to use of any

Krautkramer instrument.

General Warning

The correct and effective use of ultrasonic test

equipment requires the interaction of three essentialfactors:

The test equipment itself

The specific test applications

The operator

The principal purpose of this operating manual will be to

give instructions in the basic set-up and functionaloperation of the test equipment. Such information is

covered in detail within the manual.

Other variable factors, some of which are noted below,and the actions necessary to control them, are the

responsibility of the customer/user. Details regarding

these factors are beyond the scope of the operatingmanual.

Training

The customer must provide for adequate training of theoperators to assure competence in the operation of theequipment and in the associated factors. The operator

must be trained both in general ultrasonic testingprocedure and in the set-up and performance of a

particular test or application. The requirements forformalized training, qualification, and certification of

operators are included, for example, in SNT-TC-1A, andare referenced in many other industry specifications.

Ultrasonic Theory

Knowledge of soundwave propagation theory, including

the effects of velocity of sound, attenuation, reflection,and the limitation of the sound beam must be

understood by the operator.

Test Application Requirements

These include a definition of the test problem, selection

of suitable techniques, adequate probes, propercouplant, evaluation of discovered conditions in the test

material, and the selection of acceptance or rejectionlimits. Knowledge of the probability of occurrence ofdefective conditions is often based on experience as

well as engineering knowledge of the system and itsstresses.

Customer engineers should supply specific testapplication requirements to the operator.

Coverage and Location of Test

In ultrasonic testing, the information obtainedinstantaneously represents only the data from withinthe limits of the sound beam. Selection of test

locations as well as the degree of scanning or coverageof the part, is based on customer knowledge of

expected defective areas, material being tested,environment and similar factors. Geometry of the part,

or presence of flaws or other interfaces, may shadowcertain areas located deeper in the test material, even

though within the limits of the sound beam, thuspreventing detection of possible conditions in theshadowed area.

In testing extended areas beyond the expected soundbeam path, extrapolations or other assumptions are

sometimes based on statistical and other modificationsof actual data obtained. Such results and their use andinterpretation are the sole responsibility of the user.

Flaw Size Evaluation

In present test practice there are basically two methodsof assessing flaws. If the diameter of the sound beam

is smaller than the extent of the flaw, then the beamcan be used to explore the boundaries of the flaw to

determine its area.

If, however, the diameter of the sound beam is greaterthan the size of the flaw, the maximum echo response

from the flaw must be compared with the maximumecho response from an artificial flaw provided for

comparison purposes.

Flaw Boundary Method:The smaller the diameter ofthe sound beam, the more accurately the boundaries

can be determined. If, however, the sound beam isrelatively broad, the flaw area determination can differfrom the actual. Care should be taken to select a probewith sufficiently narrow beam at the position of the flaw.

Echo Comparison Method:The echo from a smallnatural flaw is usually smaller than the echo from anartificial comparison flaw of the same size. This isoften due to irregularity or oblique orientation of the flawsurface. This fact should be considered whenevaluating flaw size to avoid underestimating size.

In cases of very jagged or fissured flaws, e.g. shrinkholes in castings, an echo may not be detected. Insuch cases a different method may be required, suchas measuring loss of transmission through the piece.

When testing large parts, distance of the flaw from theprobe is significant. It is important to choose anartificial comparison flaw that is as near as possible thesame distance as the flaw being assessed.

Ultrasound is subject to attenuation as it passesthrough any material. Some materials attenuate lessthan others. However, if the sound travels a long

distance through the medium, then even at lowattenuation, a large effect can result.

The danger here is that natural flaws may be under-assessed. Therefore, an estimate should be made ofthe effect of attenuation on test results and appropriatecorrections applied.

If the test part has a rough surface, part of the

incident sound energy will be scattered at the surfaceand lost to the test instrument. The larger thisscattering, the smaller the echoes, and greater theunderestimation of detected flaws. It is important tomake allowance for surface roughness and apply acorrection to observed echo heights.

Specifications and Procedures

The customer must understand and provide forinterpretation and compliance with the specificationscovering its work, generated by such groups as in-house Quality Assurance, Technical Societies, IndustryGroups, or Government Agencies.

The danger here is that natural flaws may be under-assessed. Therefore, an estimate should be made ofthe effect of attenuation on test results and appropriatecorrections applied.

If the test part has a rough surface, part of theincident sound energy will be scattered at the surfaceand lost to the test instrument. The larger thisscattering, the smaller the echoes, and greater theunderestimation of detected flaws. It is important tomake allowance for surface roughness and apply acorrection to observed echo heights.

Specifications and Procedures

The customer must understand and provide forinterpretation and compliance with the specificationscovering its work, generated by such groups as in-house Quality Assurance, Technical Societies, IndustryGroups, or Government Agencies.

Ultrasonic Thickness Measurements

Ultrasonic thickness measurements are the result ofthe mathematical product of the velocity of sound in amaterial and the transit time of the soundwaves throughthe material. The transit time is the data obtained bythe ultrasonic equipment.

Velocity of SoundThe accuracy of ultrasonic thickness measurementsand of flaw location depends to a major degree on thevelocity of sound through the material. This velocityvalue is dependent on characteristics of the materialbeing tested, and is generally independent of theoperation of the test instrument.

This manual describes means for calibrating theinstrument and its internal calculations for the velocityof sound value of the test material when it is known, orfor finding the velocity of sound empirically using testblocks of the test material which are accessible forconcurrent mechanical thickness measurement. Noclaim, explicit or implied, is included as to theuniformity of the velocity of sound throughout any given

part or batch of parts. Any non-uniformity of velocity ofsound in the test material may result in erroneousthickness measurements.

Temperature Dependence

Velocity of sound is affected to varying degrees by thetemperature of the material through which the sound

travels. When temperature variables are expected,frequent checks must be made to maintain instrumentcalibration for the changing test conditions. Velocitychanges due to temperature variation may affect thematerial being inspected, transducer delay lines andother equipment components.

Doubling of Thickness Readings

When measuring relatively thin walls, with thicknessesbelow the minimum thickness specified for a particularinstrument/probe combination, down to about half

the specified minimum thickness, the first echo mayoccur while the instrument is electronically blocked toprevent false triggering. When this occurs, undercertain combinations of thin wall dimensions, surface

The USN 58R also has a Test Menu that s displayedwhenever X is pressed. This menu contains thecontrol capabilities most commonly used while testingmaterial. The Test Menu features, and their functionsare shown in Figure 1-4. Note that the function bardisplayed when X is pressed continues to bedisplayed when the Test Menu is active. Pressing Xthree more times returns to the previous menu

configuration.

1.5 Display Screen Features

The USN 58Rs displays are designed to be easy tointerpret. In Figure 1-5 youll find an example of the adisplay configuration. This specific display includes adata logger file navigation window (which allows you tonavigate through and store thickness measurements inan existing data logger file), an active A-Scan, the
