DAC/TVG R f C tDAC/TVG Reference CorrectReference Correction: While inspecting using DAC/TVG, it is common to digitally compare

the height of a reflector to the height of the curve. It is also common to use scanning i hil i i f d f S i i i h h i h f h h i hgain while inspecting for defects. Scanning gain increases the height of the echo without

changing the level of the curve.

An echo compared to a curve (in % or dB) while using scanning gain will not yield a true p ( ) g g g ydigital comparison. Reference Correction automatically removes scanning gain from the digital comparison only to allow the inspector to scan with scanning gain while still making a correct digital comparison between the echo and the curve.

DAC/TVG I tiDAC/TVG InspectionAfter building or recalling a DAC/TVG curve, inspection adjustments can be made using the different parameters in DAC/TVG menu on the EPOCH 600.

These adjustments include:– DAC GAIN– GAIN STEP– CURVE NO– VIEW

DAC/TVG I tiDAC/TVG InspectionDAC Gain adjustment either raises or lowers the gain of both the echo and the curve.

Since DAC codes require that any indication be sized above 20% full screen height, the usable range of a basic DAC curve is often limited.

DAC Gain allows an operator to inspect indications that occur at longer sound paths in a material by simply adjusting the overall gain to bring the curve and indication higher than 20% FSH.to bring the curve and indication higher than 20% FSH.

Warning Curves allow inspectors to more accurately size indications that are relatively larger or smaller than the main DAC curve.

Typical warning curves are set at +/- 6.0dB from the main curve, as well as -14.0 dB (ASME-3).

An echo below the main curve that An echo below the main curve that exactly matches the height of a -6.0dB warning curve indicates a flaw ½ the size of the reference reflector.e ecto

DAC/TVG I tiDAC/TVG InspectionVIEW adjustment toggles between the DAC curve view and TVG view.

TVG (Time Varied Gain) represents indications from the same sized reflector at varying depths within a material as a 80% FSH echoes by varying GAIN across the EPOCH 600’s screen rangethe EPOCH 600 s screen range.

TVG allows faster flaw scanning by bringing potential defects to code-compliant sizing heights without constant adjustment of DAC GAIN.

VIEW adjustment allows dynamic switching from DAC to TVG based on a single DAC setup providing the power ofsingle DAC setup, providing the power of both methods to an operator without extensive setup time.

DAC/TVG C tDAC/TVG Custom Various inspection codes exist in different markets that prescribe the use of DAC and/or TVG for flaw

sizing.

Within these codes, Warning Curve levels are often defined to meet the code’s sizing requirements. Examples are:

– ASME – One DAC curve representing the reference reflector height– ASME-3 – Three DAC curves at Reference, -6.0dB and -14.0dB

JIS Positive and Negative curves at every +/ 3 0dB– JIS – Positive and Negative curves at every +/-3.0dB

The EPOCH 600 features CUSTOM DAC/TVG Mode, which allows the operator to define up to 3 Warning Curves (in addition to the main Reference curve) fromWarning Curves (in addition to the main Reference curve) from -24.0dB to +24.0dB from Reference.

DAC/TVG C tDAC/TVG CustomCUSTOM DAC/TVG Mode also allows the operator to define the Curve Type for these custom Warning Level curves:

POLYNOMIAL – Connects the acquired reference points with a curved line which interpolates the attenuation of sound between each reference reflector (similar to ASME and ASME-3 code requirements).

STRAIGHT – Connects the acquired reference points with straight line segments (similar to the JIS code requirements).

AWS D1 1/D1 5AWS D1.1/D1.5The EPOCH 600 includes AWS weld rating software as an optionalfeature. The EPOCH 600 AWS software is intended to assist weld inspectors performing AWS-compliant inspections.

AWS D1 1/D1 5AWS D1.1/D1.5The AWS code provides inspectors with a method to classify discontinuities found in welds using ultrasonic inspection. This code uses the following formula to develop an indication

i f fl f d d i i irating for a reflector found during an inspection:

A – B – C = DA B C D

A = Discontinuity Indication Level (dB)B = Reference Indication Level (dB)C = Attenuation Factor: 2 x (soundpath in inches – 1 inch) (dB)D = Indication Rating (dB)

An AWS D1.1 inspector must take the Indication Rating (D) that is calculated based on A, B, and C to an Ultrasonic Acceptance – Rejection Criteria table produced by the AWS in order to classify the severity of the discontinuity that has been located.

DGS/AVGDGS/AVGThe EPOCH 600 offers on-board DGS/AVG capabilities as an optional feature. The DGS/AVG software option features a comprehensive library of transducers from both Olympus NDT and competitors.

DGS/AVG O iDGS/AVG OverviewDGS/AVG is a flaw sizing method that compares the height of a reflector to a curve which

represents the expected height of a known defect size at various sound path lengths within a part. DGS/AVG is similar to the DAC flaw sizing method, but with notable p g ,differences:

Reference Curve(s) not built point by point using reference reflectors – instead, curve(s) based on DGS Diagrams which predict the echo response (and attenuation) of multiple reflector sizes over a particular sound path range in carbon steel.

DGS/AVG ParametersDGS/AVG Parameters

DGS/AVG setup includes up to 10 parameter selections/adjustments before the operator can begin inspections:p g p

Probe Type – The operator must select the type of probe used in the inspection (either Straight Beam, Angle Beam, or Dual Probe)

Probe Name – The operator must indicate exactly which probe is to be used in the inspection (DGS curves are based partially on the response of a specific probe in steel)

Reflector Type – A single reference reflection is required to build the DGS curve(s) on the EPOCH 600 – this can be from a Backwall, Flat-Bottom Hole (FBH), Side-Drilled Hole (SDH), K1/IIW Block Radius*, or K2/DSC Block Radius*

*used only with Angle Beam probe

DGS/AVG P tDGS/AVG Parameters Reflector Diameter – When a Reflector Type of SDH or FBH is selected, the operator

must indicate the size of the reference hole.

Delta VT – Also known as Transfer Correction, Delta VT is a calculated value the accounts for an overall attenuation difference between a reference/calibration block and the actual inspection piece (typically caused by surface conditions or subtle material variation)

Registration Level – The value of the “critical” reference reflector for the inspection. This defines the relative height of the DGS curve and the comparison to unknown flaw g preflections for rejection/acceptance criteria.

Warning Level – DGS/AVG allows for one Warning Curve in addition to the main DGS curve This can be set from +6 0dB to -14 0dB below the main curve or to 0 0dB to turncurve. This can be set from +6.0dB to 14.0dB below the main curve, or to 0.0dB to turn this curve off.

DGS/AVG P tDGS/AVG Parameters ACV Specimen – An attenuation compensation value for the inspection piece. This

value is used to adjust the DGS curve, which is based on attenuation in an “ideal” or “ f ” b l fl i i “ l ld”“perfect” carbon steel, to reflect accurate attenuation response in a “real-world” test piece. This is especially important for longer sound paths. The calculation for this attenuation adjustment is defined in the code EN 583 and other documents.

ACV Calibration Block – An attenuation compensation value for the calibration block. This value serves the same purpose as ACV Specimen, but is used when capturing a reference reflector from the calibration block.

X-Value – This parameter is only used with Angle Beam probes. This value is the distance from the Beam Index Point to the front of the angle beam probe/wedge. It is used to remove this wedge distance from the Surface Distance measurement and allows operators to locate a flaw on a test piece by measuring from the front of the transducer, p p y g ,instead of from the Beam Index Point, which can be less accurate or difficult during inspection.

API 5UE

API 5UEAPI 5UEThe EPOCH 600 includes API 5UE crack sizing software as an optional feature. The EPOCH 600 API 5UE software is intended to aid operators using API Recommended Practice 5UE in the evaluation of crack height sizing during the pipe fabrication process.

API 5UE O iAPI 5UE OverviewThe API Recommended Practice 5UE was developed specifically for OCTG manufacturers to inspect and characterize inner-diameter (ID) cracking in newly fabricated pipe. The API 5UE code uses two crack sizing methods to characterize ID cracking: the Amplitude5UE code uses two crack sizing methods to characterize ID cracking: the Amplitude Comparison Technique (ACT) and the Amplitude-Distance Differential Technique (ADDT). The software developed for the EPOCH series aids in performing the ADDT method, which uses the following formula to determine ID crack size:

di = Amax*(T2-T1)*k

di = imperfection sizedi = imperfection sizeAmax = Maximum amplitude returned from defect area (usually 80%)T1 = 6dB drop point from leading peak of Amax (distance or time)T2 = 6dB drop point from trailing peak of Amax (distance or time)k = a constant calculated from calibration to a reference notch

An inspector utilizing API 5UE must use the formula above to establish a crack height and refer to the API code for rejection or acceptance criteria.
