PHASED ARRAY MODE: OVERVIEW and PERFORMANCE
Phased Array Mode Overview Phased Array Mode: Standard Group Menus
Phased Array Mode - Overview u Phased Array Imaging The EPOCH 1000 Series provides manual phased array imaging capabilities, either standard or optional, based on the following: – EPOCH 1000 – Optional imaging requiring hardware/software upgrade – EPOCH 1000 i. R – Optional imaging requiring only software upgrade – EPOCH 1000 i – Standard imaging capabilities u Manual Imaging Manual imaging means that the images acquired cannot be encoded. The EPOCH 1000 Series phased array capabilities is designed for hand scanning applications to augment conventional techniques.
Phased Array Mode - Overview Angle Beam Inspections Phased array angle beam inspection typically provides two views: u Sector Scan This image represents a composite of A-scans across a range of angles (typically 40°to 70°). This sector scan shows amplitude data of each angle in the angular coverage area at the same time. u A-scan An individual A-scan is displayed from the sector scan. This A-scan represents a single angle, and is selected using a cursor. A-scan at 60°(selected)
Phased Array Mode - Overview Straight Beam Inspections Phased array straight beam inspection typically provides two views: u Sector Scan This image represents a composite of A-scans across a range of angles (typically -30° to +30°). This sector scan shows amplitude data of each angle in the angular coverage area at the same time, including the 0° A-scan. u A-scan An individual A-scan is displayed from the sector scan. This A-scan represents a single angle, and is selected using a cursor. This is usually the 0° A-scan in straight beam applications. A-scan at 0°(selected)
Phased Array Mode - Performance u Automated Gain (Sensitivity) Calibration The EPOCH 1000 Series features an automated sensitivity calibration procedure during phased array setup. This automated procedure, based on the Omni. Scan sensitivity calibration, allows the user to capture the peak amplitude response from a single reflector (usually side drilled hole) across all imaging angles (focal laws). The instrument then uses this amplitude capture to adjust gain at each angle (focal law) to position the amplitude from this reflector at 80% FSH for every A-scan. Gain Calibration Curve
Phased Array Mode - Performance u Automated Wedge Delay Calibration The EPOCH 1000 Series features an automated wedge delay calibration procedure during phased array setup. This automated procedure, based on the Omni. Scan wedge delay calibration, allows the user to capture the TOF/distance measurement from a single reflector across all imaging angles (focal laws). The instrument then uses this TOF/distance capture to adjust the wedge delay at each angle (focal law) to provide correct TOF/distance measurements for every A-scan. Wedge Delay Calibration Curve
Phased Array Mode - Performance u Image Smoothing Phased array imaging is based on composited amplitude responses of multiple A-scans. In many instances, A-scans can have multiple peaks when reflected from a single defect. This can affect the clarity of the S-scan. The EPOCH 1000 Series, therefore, allows the user to select stepped image smoothing, applied to both the A-scan and S-scan, to provide clearer images without significant impact on the precision of the measurement.
Phased Array Mode - Performance u Frozen Image Analysis The EPOCH 1000 i allows A-scan and image review and analysis while in FREEZE mode – Raw A-scan data available for all angles/focal laws – Full Gain, Gate and Cursor adjustment – A-scan indication measurements live – Image sizing cursors available for X 2 – X 1 and/or Y 2 – Y 1 indication sizing
Phased Array Mode - Performance Phased Array Specifications The EPOCH 1000 i is a powerful conventional flaw detector with basic, manual phased array imaging capabilities. The specifications below are critical when compared to other phased array instruments to understand the benefits and limitations of the EPOCH 1000 i.
Phased Array Mode - Performance Phased Array Imaging for the Conventional Inspector u u Better probability of detection through imaging Comply with Conventional Codes and Procedures! – Use imaging for faster and more confident detection – Use fixed-angle A-scan for standard defect characterization – No compromise to conventional performance u More efficient inspections – One Probe – One Calibration – Full Inspection u As easy to use as a conventional flaw detector!
Phased Array Mode - Performance Conventional Inspections Made Easy with Phased Array! Tip Diffraction Application Video AWS Application Video
PHASED ARRAY MODE DEMONSTRATION The following topics should be demonstrated using a live instrument and demonstration probe/test piece: – Auto Probe ID – Beam Menu Setup – Custom Probe/Wedge Setup (Intent) – Display Views – Gate Setup – Auto-XX – Calibration Overview » Zero and Angle » Velocity » Wedge Delay » Gain » Multi-Point Gain – Image Overlays – Image Cursors
Phased Array Software Features Standard Sizing and Evaluation Techniques Coming soon in early 2009! u As with conventional UT mode, the phased array mode incorporates the following standard sizing techniques: – DAC/TVG – DGS/AVG – AWS u These techniques are critical to allowing the EPOCH 1000 i to be fully compliant with conventional codes, while still providing imaging benefits.
Phased Array Mode – Software Features DAC/TVG The EPOCH 1000 i has the capability to create a TVG setup during sensitivity (gain) calibration, as demonstrated earlier. This TVG setup is the same process as acquiring a DAC curve – it allows the user to reference the amplitude response of a known reflector at varying depths within the test piece. The EPOCH 1000 i will allow the user to utilize this simple TVG setup mode during sensitivity (gain) calibration to create an individual DAC curve for every focal law. – – DAC curve will only be viewable on the selected A-scan DAC measurements will be active for the selected A-scan S-scan will always display in TVG view Available in early 2009
Phased Array Mode – Software Features DGS/AVG The EPOCH 1000 i also has the capability to create a DGS/AVG setup. However, since DGS/AVG is only valid for qualified probes at certain fixed angles, the DGS/AVG curves will not apply to all focal laws. The EPOCH 1000 i will allow the user to utilize a similar setup menu as the DGS/AVG conventional setup, to calculate DGS/AVG curves for specified focal laws (typically 45°, 60° and 70°). – Atlas-DGS Phased Array Probes must be used » 4 L 16 -DGS 1 » 2 L 8 -DGS 1 – DGS/AVG curve will only be viewable on the selected A-scan – DGS/AVG measurements will be active for the selected A-scan – Available in early 2009
Phased Array Mode – Software Features AWS D 1. 1/D 1. 5 Weld Rating Software The EPOCH 1000 i will have the capability to evaluate the ‘D’ weld indication value according to the AWS calculation of A-B-C=D for all three standard inspection angles (45°, 60° and 70°). This will allow the user to comply with the AWS code while gaining inspection speed and confidence. The EPOCH 1000 i will allow the user to turn on the AWS feature and select a desired reference gain level (AWS stipulates over 50% FSH). The user will then use a tool similar to the sensitivity calibration tool to acquire a Ref. B value for all focal laws at once. – AWS Phased Array Probe should be used » 2, 25 L 16 -AWS 1 – Multi-law mode will be active, allowing the operator to only view A-scans that represent 45°, 60° and 70°. – Available in early 2009
Troubleshooting Techniques It is important, especially early in a product release, to identify ways to correct common issues or software glitches. This section describes three methods of correcting instrument failures and/or problems. – Instrument Resets – Hard Reset – Compact Flash® Reset
Troubleshooting Techniques Instrument Resets The EPOCH 1000 Series has several instrument resets built into the software u u u Location: FILE group menu, RESETS parameter menu Corrects symptoms: – Parameter cannot be adjusted – Function/parameter seems to be missing – Instrument is operational but “acting funny” Resets include: – Master/Database – clears data logger, restores default parameters – Parameters – maintains data logger, restores default parameters
Troubleshooting Techniques Hard Reset The EPOCH 1000 Series features an external, hard reset function u Create a file on a USB memory stick called ‘reset. txt’ – File does not need to contain anything, just have this exact name/extension u u Turn off the instrument Plug USB memory stick into instrument Turn on the instrument Corrects Symptoms: – Unit will not finish loading after initial start up – Strange functions and crashes that instrument resets do not solve u Reset clears data logger and restores factory default settings to instrument
Troubleshooting Techniques Compact Flash® Clear The EPOCH 1000 i stores limited phased array probe information on the Compact Flash® card. If this data gets corrupted, clearing the flash card may solve any issues. u u Resets any custom phased array probe setups Corrects Symptoms: – Instrument displays a ‘PA_Benchmark. exe’ error upon boot up – Instrument will not complete boot up after a software upgrade u u u Rare requirement User must have a Compact Flash® reader to perform the clear Simply delete all files on flash card, return to instrument and turn on
