Paut based techniques developed for power industries and refinery in taiwan ...Yung how Wu
Although conventional ultrasonic method is still widely used elsewhere, PAUT technique is applied increasingly for improving the ISI of utility, refinery and as well the emerging wind power in Taiwan. PAUT together with scanner is one of the major advantages to precede conventional UT by enhancing the defect characterization or inspection speed. In this study, special scanners were designed and employed with PAUT for the inspection of composite blades, bolts of wind turbine and anchor bolts of nuclear RPV skirt. Results showed that delamination of composite and fatigue crack of bolt may be detected and sized in more confidence and convenience for in-situ inspections. Moreover, PAUT was also used to characterize carefully the inner crack of pressure vessel for FFS assessment. Crack was found in safe margin and hence remained to operate. In conclusions, PAUT together with manipulator designed for specific purpose may facilitate the applications of PAUT technique widely in ISI of various industrial sectors.

Scalable NDT Instruments for the Inspection of Variable Geometry ComponentsOlympus IMS
For the past several years, the aviation industry has seen above normal growth due, in part, to lower oil prices, saving major aircraft operators millions of dollars. As a result of this outstanding growth, production rates for new airplanes have increased and new aircraft programs are being launched. Consequently, aviation component manufacturers are facing new challenges including a rise in production rates, a high probability of detection (POD) due to the critical nature of the parts being manufactured, lack of skilled operators, and parts with increasingly complex geometry.
Ultrasonic phased array (PA) instruments have evolved, enabling an increase in inspection speeds and the implementation of advanced acquisition strategies. The introduction of scalable instruments and advanced acquisition strategies helps manufacturers address the inspection challenges they are facing. Scalability can now be used for nondestructive testing (NDT), enabling system integrators and manufacturers to improve the performance of their solutions by using multiple instruments in parallel. The evolution of electronic components enables advanced acquisition strategies, such as adaptive ultrasound, to be implemented. Adaptive ultrasound simplifies the inspection of complex components and improves the POD by using innovative signal-processing algorithms.
This paper presents an overview of scalable NDT instruments with the goal of helping NDT integrators and manufacturers to address the challenges they are facing in terms of system performance, production output, and quality control.

Question: For precision sizing of weld flaws using OmniScan phased array inspection, which is the preferred technique: Shear wave tip diffraction or amplitude drop sizing?
Answer: The decision to use shear wave tip diffraction or amplitude drop sizing is dependent on the flaw type, size, and orientation. In general, if the flaw is larger than the beam size and is near perpendicular to the beam as is typical in side wall lack of fusion, amplitude drop sizing will produce most accurate results. If the flaw is smaller than the beam size such as a crack ligament then tip diffraction will be most accurate.

Advances in Phased Array Weld Inspection Scan Plan DesignsOlympus IMS
The compound S-scan improves on traditional phased array weld inspection scan plan strategies by combining the S-scan and E-scan inspections as defined in ASME V, Article I into a single acquisition group providing more inspection coverage of the weld volume and heat affected zone. The compound S-scan improves the range and performance of existing phased array 1D pulse-echo probes, wedges, and instrumentation via new functionality in focal law calculators that are commercially available today from Olympus and other manufacturers.
Additional benefits of the compound S-scan inspection include ability to use pre-defined configurations over a larger range of weld bevels and thicknesses, enforcement of fewer essential variables in the inspection work procedure, and a more efficient work flow for phased array inspection setup, calibration, acquisition, and data analysis IAW ASME V, Article 4, Phased Array Mandatory Appendixes IV and V.

Eddy Current Array Inspection of Carbon Steel Welds with Dynamic Lift-Off Com...Olympus IMS
The use of eddy current array (ECA) technology has already been shown to increase the speed of inspections and the reliability of the surface inspection process. However, surface inspection of carbon steel welds used in pipelines and pressure vessels represents many challenges for this technology. The geometric shape of the weld crown, the paint thickness, the presence of crest and crowns, and the ferromagnetism of the carbon steel are constraints.
New tools have recently been developed to help overcome these challenges. A new orthogonal-type ECA probe based on flexible printed circuit board (PCB) technology conforms to the shape of the weld to help ensure flaw detection. Dynamic lift-off compensation and depth sizing tools were then added to a modern flaw detector, resulting in a leading-edge solution that can potentially replace Magnetic Particle Inspection for carbon steel weld inspection. With these inspection tools, users can fully benefit from the portability, imaging, data archiving, and reporting capabilities of eddy current array instruments.
In this paper, we review this new carbon weld inspection solution and present results that demonstrate the solution’s effectiveness for inspecting carbon steel welds. This presentation is technically advanced and is addressed to NDT operators and engineers.
When using ultrasonic flaw-detection equipment, it is essential that the performance characteristics are known.
Calibration should be repeatable and operator-independent, especially in situations where flaw growth is being monitored at discrete intervals. In order that changes due to wear, component temperature or other causes may not go un-noticed, the calibration measurements should be repeated at frequent intervals.
Probes, especially, must be checked before commencing and after completing critical work to ensure the validity of the entire measuring results.
Prior to the release of the ISO 19675:2017 calibration block, the techniques to calibrate and assess these performance characteristics for an ultrasonic phased array inspection were performed in a variety of ways in different parts of the world. Existing calibration blocks did not allow checks for all the necessary phased array code and standard requirements, therefore adapted blocks for calibration procedures were implemented by a select minority of expert engineers.
The ISO 19675:2017 block allows for all ultrasonic testers, worldwide, a simple and consistent tool and allows for widespread adoption of phased array ultrasonic inspections across many industries. It was also designed to allow to check probes as specified in other ISO standards.
the new ISO 19675:2017 is a flexible and simple tool for calibrating combined equipment and it offers more than the ISO 2400 block for both conventional and linear phased array setups. This calibration block will become a useful tool that is used in industry for calibration of ultrasonic inspections. The workflow structures and calibration wizards in modern portable flaw detectors have been designed for easy, repeatable calibration.
Proceq’s own developed broadband probes show greater sensitivity than traditional PZT transducers, the necessary gain to detect a 1.6 mm hole in the ISO 19675 block was over 9 dB lower, however further development of different probe types using this proprietary crystal is necessary to expand the application and usages in the field of NDT.

Probes, especially, must be checked before commencing and after completing critical work to ensure the validity of the entire measuring results.
Prior to the release of the ISO 19675:2017 calibration block, the techniques to calibrate and assess these performance characteristics for an ultrasonic phased array inspection were performed in a variety of ways in different parts of the world. Existing calibration blocks did not allow checks for all the necessary phased array code and standard requirements, therefore adapted blocks for calibration procedures were implemented by a select minority of expert engineers.
The ISO 19675:2017 block allows for all ultrasonic testers, worldwide, a simple and consistent tool and allows for widespread adoption of phased array ultrasonic inspections across many industries. It was also designed to allow to check probes as specified in other ISO standards.
the new ISO 19675:2017 is a flexible and simple tool for calibrating combined equipment and it offers more than the ISO 2400 block for both conventional and linear phased array setups. This calibration block will become a useful tool that is used in industry for calibration of ultrasonic inspections. The workflow structures and calibration wizards in modern portable flaw detectors have been designed for easy, repeatable calibration.
Proceq’s own developed broadband probes show greater sensitivity than traditional PZT transducers, the necessary gain to detect a 1.6 mm hole in the ISO 19675 block was over 9 dB lower, however further development of different probe types using this proprietary crystal is necessary to expand the application and usages in the field of NDT.

Benefits of 3D Visualization for High-Resolution Video MeasurementOlympus IMS
Industrial videoscopes continue to improve with advanced features like high-resolution imaging and stereo measurement. While these advancements help inspectors obtain more accurate RVI measurements, this accuracy still relies on one thing—how precisely the inspector picks their reference and measurement points.
So, how can inspectors confidently select the correct points? The answer lies in 3D modeling.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

NDT PV100 series
1. Olympus NDT PV100 Series
Nicholas Bublitz
Global Products Support Specialist
2. PV Series Description
The PV Series is a “solution” package. Different configurations can
meet customer’s applications.
3. PV (Pressure Vessel) Series Description
The “PV” Series solutions
include:
– Acquisition unit
– Scanner
– Applicable Accessories
– Setup and Analysis Tools
5. Applicable Customers and Codes
♦ PV100 is predominately geared towards
the following two customers
– Manufacturing companies utilizing
AWS, API and ASME codes for weld
inspection (pressure vessels, piping
etc.).*
– Service companies performing weld
inspection to AWS and ASME and
API requirements*
*and other codes outside North America
6. Wind Tower Manufacturers
♦ Typically inspected with manual
shear wave to AWS D1.1, a typical
tower weld is 14-40’ in circumference
taking hours to manually inspect a
single weld with no record of data
♦ Radiography is often used as well.
Besides disruption of production or
movement of parts to a safe area,
radiography does not provide depth
information for repairs
7. Service Providers
♦ Many manufacturing weld inspection services are
outsourced to an outside source.
♦ Also, many welds in oil and gas, structural and other
industries require regular inspection to ensure safety.
♦ AUT systems like the PV100 series offer many
unique advantages over more conventional
ultrasonics and radiography.
9. PV100 Description
♦ PV100 is a generic description for a weld inspection
package utilizing more conventional ultrasonic
techniques (Shear wave, TOFD, Creeping Wave)
♦ Package tools are determined predominately by wall
thickness and code conformance
♦ Although we use PV100 generically, there are
actually several packages available based upon
customer requirements (PV100-101-102)
10. PV100 Technique
♦ Technique varies on applicable code
requirements and wall thickness
– PV100 Wall thickness ~10-30 mm
– PV101 Wall thickness ~30-160mm
– PV102 Wall thickness ~150-300mm
♦ Application Example: Typical wind
towers have a thickness range of 12
– 46mm. They might utilize both the
PV100 and 101 techniques.
11. PV100 Ultrasonic Techniques
♦ PV100 incorporates TOFD for the
volume and shear wave Pulse
Echo for the weld cap and root
(from each side)
♦ PV101 incorporates 2 channels of
TOFD (volume and root) and
Creeping wave for the weld cap
♦ Other configurations of these and
other conventional ultrasonic
methods (refracted longitudinal
wave etc.) may still be referred to
as PV100 generically
12. TOFD
♦ Uses send and receive
probes
♦ The incoming wave vibrates
the defect and emits energy
in all directions
♦ The receiver gets one or
more signals from the defect
14. TOFD Limitations
Blind areas :
– Near surface Due to the width of the lateral wave as well as timing
inaccuracies Can be reduced by reducing PCS, using higher frequency probes,
incorporating highly dampened broadband transducers, as well as software
tools (lateral wave removal). These minimize, but do not eliminate the near
surface dead zone.
– Back wall Large signal from reflected energy at the back wall
creates a dead zone as well
15. Recommended Solution
♦ TOFD is a very good tool for weld
inspection.
♦ However, it does have some
limitations, Pulse Echo can cover
these limitations.
♦ SOLUTION: Incorporate both TOFD
and PE simultaneously
♦ Pulse Echo channels can be targeted
on the cap and root, TOFD’s weak
spot for a full volumetric inspection.
17. TOFD Data
♦ Side View
♦ Grey scale palette
♦ Sized with cursors
Top
Volume
Back Wall
18. PV100 Principles
A combination of both TOFD &
Pulse-echo channels, proves
to cover the weld zone
generously when setup
correctly
19. PV101 Technique
♦ PV101 adds multi-zone TOFD
with the addition of the
creeping wave technique
♦ This is implemented to address
possible poor detection and
sizing with pulse echo at the top
on thicker material
♦ Creeping waves are designed
to cover just a few millimeters
below the surface for defects.
20. Radiography Replacement
♦ The PV series is suitable for
codes where radiography
replacement by ultrasonics is
allowed
♦ Some of the benefits include
no radiation hazards to
contend with, no need to stop
other productions, and height
sizing

Editor's Notes
The PV Series of solutions are designed to offer improved weld inspection equipment for a variety of customers from manufacturing to in service. It has been very successful in the wind tower manufacturing market and for replacement of radiography applications. It can be applied to a wide range of applicability of diameters and wall thickness as seen in this slide.
The PV100 is a complete product offering geared toward circumferential weld scanning with encoded data. The solution is made up of an acquisition unit, a scanner, all applicable probes and wedges and other accessories, as well as setup and analysis tools. The actual components can vary by customer applicable components, codes, and other needs. The solution is either a semi-automatic (encoded but operator driven) or fully automatic solution. PV stands for pressure vessel as it was originally derived to fulfill pressure vessel oriented codes like ASME CC 2235-9.
Olympus NDT employs several different ultrasonic techniques pictured above. The PV 100 series of techniques focuses on Pulse echo, Time of Flight Diffraction, and the use of Creeping wave transducers as required. More detail on these techniques will be shown in later slides.
The PV100 solution is primarily geared towards two customers: Customers who manufacture new welds and service companies who inspect welds that have already been put into service. The most common codes governing these type of welds in the United States are AWS, ASME, and API. Common applications include: pressure vessels (ASME Section I/VIII Div I and II/XII), as well as structural welds like the windmill tower base shown here which is usually governed by AWS D1.1.
Wind Mill Tower base customers usually fall into one of two categories, either the manufacturing or sub-manufacturing companies. These companies often are already inspecting the welds with conventional flaw detectors and/or radiography as well as possibly magnetic particle and liquid penetrant inspection. Manual shear wave of these very large weldments can take hours since the outside diameter of various sections typically varies from 14 to 40 feet. The typical output from manual inspection is a signed report with no auditable data. Radiography, while able to produce an auditable output, has several disadvantages including: safety, the need to clear an area or move the component and a lack of depth and height of flaw information.
Inspection companies are also a great potential customer for the PV100 Solution.
PV100 is a generic term used freely to represent a scanning solution utilizing the combination of conventional pulse echo shear wave techniques along with TOFD (Time of Flight Diffraction) to provide volumetric weld inspection for in-service and newly manufactured welds. Based on code and coverage requirements other techniques (Creeping wave, double zone TOFD etc.) can also be part of the total PV solution. There are actually several pre-packaged solutions to start from when examining a customer’s requirements. They are split up by the thickness of the weld to be inspected and can be tailored to fit any number of other customer requirements as needed.
As mentioned the PV100 can vary in the exact technique employed. The main deciding factor is code requirements and part thickness. The main techniques for most thicknesses are TOFD and shear wave pulse echo. As the thickness increases we utilize other techniques like creeping wave and focused sets of Tofd to comply with the code and get sufficient coverage. Typical wall thicknesses seen for wind mill tower bases is 12-46 mm, but can vary by tower design and manufacturer.
Tofd is used as the primary technique in the basic PV100 technique to cover the volume of the weld. Shear wave at varying angles are then used to compliment this technique to cover the uppermost and bottom most portions of the weld (Cap and Root). As the materials get thicker it may be necessary to utilize a PV101 approach of dual Tofd (volume and root) and creeping waves for the top surface. Special applications may include other ultrasonic techniques including refracted longitudinal waves which is common for austenitic material, these also may be referred to generically as PV100 packages.
Tofd or Time of Flight Diffraction utilizes diffracted energy versus the commonly utilized reflection technique of shear wave inspection. Using a send transducer to input the sound into the material on one side of the weld and a receive transducer on the opposite side of the weld to “listen” for any sound diffracted off any weld anomalies. Because of its wide beam nature of tofd we are able to cover large areas of the weld with a single pair of Tofd transducers.
The technique lends itself to be very sensitive to all weld anomalies regardless of orientation unlike pulse echo techniques. Once a discontinuity is struck it will vibrate and it will emit diffracted energy in all directions allowing it to be readily detected. Height and length measurements can also be more precise than reflection techniques since the TOF or time of flight is analyzed versus the amplitude of the reflected energy.
Tofd is relatively assumed industry wide to have two weak areas because of the wave physics, one near the top surface , and one at the far surface or back wall of the component. Although these can be minimized they always exist to some extent.
To overcome the weakness at the near and far surfaces, pulse echo shear wave transducers are focused at the cap and root areas. When we combine these techniques we arrive at the PV100 solution, full volumetric weld inspection.
The PV100 solution follows this technique, allowing for simultaneous cap, root and volume inspection giving full coverage with a single data set. All probe positions and angles are input linking the individual channels into a single acquisition file in one scan or pass around or down the weld. When either acquired or post analyzed in TomoView software all channels are visible at one time. Here we see a typical PV100 inspection in the TV Software program.
Side Views (B or D scans) are typically utilized for both the Tofd and shear wave channels. Once a defect is identified it would be measured with cursors for its length and thru-wall height with acceptance/rejection criteria applied.
When employing the PV100 system, all setups can be saved into the OmniScan for recall when applicable. For probe positioning companies with common welds usually produce a setup chart to facilitate changing from one weld configuration to another. Because of the wide beam nature of Tofd a single set of probes and wedges can cover a large range of thicknesses without the need for changing out equipment. Here we can see the sections from 14 mm to 25 mm all being covered with the same type of Tofd and shear waves probes and wedge angles at different index positions (position from center of weld). Procedure development programs like NDT Setup Builder facilitate proper probe and wedge selection and placement.
As mentioned previously, as welds get thicker we often use creeping waves to assist in code compliance and coverage. Here a scanner is shown utilizing Tofd at both the root and volume and a pair of creeping wave transducers covering the very top of the weld. The creeping wave transducers are designed and setup to cover only a few millimeters below the surface where the first zone of Tofd will have a weakness. By refocusing the second pair of Tofd lower into the volume we are able to get sufficient coverage and detection at the back wall area.
It has been very popular in recent years to use AUT techniques to replace radiography applications. Ultrasound lends itself to safe deployment without interrupting work going on around it. It also offers accurate depth and thru wall height sizing which often can allow for fracture mechanics or ECA criteria to be applied. With radiography the depth and height of the discontinuity are often unknown . Shown here is a comparison of the Tofd technique and radiography technique on the same weld specimen.
Typically the first part of an encoded PV100 examination is designing a scan plan to ensure coverage and detection capability. The part is drawn in and the applicable transducers are placed accordingly. This is usually also a code requirement to document this plan. With NDT Setup Builder this setup can then be imported into the OmniScan platform to do the acquisition.
Typically the OmniScan platform with an 8 channel conventional ultrasound module is used for acquisition. It can be operated directly off the mainframe or driven by a laptop with the TomoView software. The main difference between choosing to use TomoView or OmniScan only for acquisition is data display while scanning. The OmniScan will offer a single channel view, while TV will allow for all acquisition channels to be viewed simultaneously while scanning. The OmniScan platform allows for further expansion into phased array Ultrasonics by changing the acquisition module while keeping the same general user interface.
Typically only a semi-automatic scanner is required. The HTSM-Flex offers all the necessary probe holders and other capabilities to perform the PV100 technique, including space for a preamp for the Tofd channels, water manifold for Couplant delivery, magnetic wheels, and rulers for probe positioning. The HSMT-X03 is another option. It is also possible to utilize an automated scanner like the Weld Rover to perform PV100 techniques. An automated option will typically offer improved data as the acquisition speed and control of the scanner is more controlled then the manually driven semi-automatic scanners. Full details of each scanner option can be seen in the Industrial Scanner Brochure
Water is typically utilized as Couplant to ensure adequate consistent coupling during the scanning. Regulated pumps like the CFU-03 can be used, or portable manual water sprayers can be used. In some environment additives can be added to keep the water from freezing.
Post analysis of data can be done on the OmniScan but the use of a PC and analysis software is usually preferable. OmniPC or TomoView can be used for this purpose. OmniPC has the advantage of having the same user interface as analysis on the OmniScan itself so it is easy to use and requires little to no training. TomoView has some advanced processing tools like file merging and offline gain adjustment. These features are used often in phased array inspections but less in the typical PV100 application. A configured Industrial style laptop can be acquired with all the necessary software to analyze and report findings. Shown above is a typical data display in both OmniPC and TomoView. The shear wave channels are typically set to an amplitude response pallet, so defects reaching reject level can be easily discerned by color. Measurements can be quickly acquired by cursors and readings . The results can be reported directly out of either software into a Windows friendly format for easy distribution.
Depending on the customer’s needs there are a lot of smaller components that typically go into a PV100 solution as well including: cabling, probes, wedges, spare parts etc. All necessary components can be identified based on the welds to be inspected so a total solution package is offered. If needs change, other accessories can be added later. Umbilical or divisible cable style wiring is typically used to group all the necessary inputs into one strand.
Typically the length, height, amplitude and position of an indication are needed for reporting. These and other user selected readings are readily available and will be included on the report. The standard report can be customized with a variety of views and readings, or screenshots can be taken for custom reports in other software programs as needed.
Performance and Calibration blocks are used to calibrate the velocity, wedge delay, sensitivity, as well as any material attenuation correction needed. They are also used to demonstrate that the technique is valid and to test operators ability to run the system and size defects adequately. These blocks typically cover a range of thicknesses, the number of blocks needed will depend on the welds being inspected and the procedure/code criteria. They typically use notches and Side drill holes (SDH) for calibration and demonstration capabilities. Typically one to two performance blocks will be required to cover a typical wind tower base manufacturers range of thicknesses, service companies may have to make job specific blocks as jobs are acquired. The location of calibration reflectors and other requirements of these blocks should be spelled out in the applicable procedure and codes.
