Conventional and Phased Array UT Solution
In many industries, such as in the oil and gas industry, countless welded tubes and pipes must be inspected throughout their entire service life. Olympus NDT has introduced an integrated weld inspection solution based on the field-proven OmniScan flaw detector and a new series of probes dedicated to manual weld inspection.
The Manual Weld Inspection Solution from Olympus NDT, which includes the OmniScan M instrument and a new phased array (PA) Weld Probe Series, provides major benefits: higher inspection speed, greater probability of detection, and better reporting and traceability. New features and improvements in the OmniScan M Weld software make this solution easy to use and well suited for both PA and UT inspections. The solution is compliant with the most important standards: AWS, API, DGS, ASME-V, and JIS.
In addition, a very helpful RayTracing™ feature allows the weld area covered by your PA configuration to be visualized in real time. An added benefit of PA is that only one phased array probe is needed to produce all inspection angles.
The Manual Weld Inspection Solution Offers:
- OmniScan M instrument
- OmniScan M Weld software adapted for manual weld inspection, featuring:
- UT flaw detector user interface and features
- Familiar menu-driven interface
- Sizing curves (DAC/TCG, ASME, JIS, and DGS)
- AWS and API code wizards
- Intuitive RayTracing™ feature provides a visual display of the phased array beams in the part
- Weld overlay feature simplifies data interpretation
- PA Weld Probe Series (WPS)
- Ergonomic design and smaller footprint
- DGS and AWS code-compliant PA probes
OmniScan M Instrument
The low-cost, entry-level OmniScan M module brings the advantages of phased array imaging to manual testing, while keeping all the benefits of a proven product.
Manual Phased Array Module (16:16M/16:64M)

Manual Weld Software
Flaw Detector User Interface
Because the OmniScan Weld software (MXU-M-2.1-WELD) is very similar to the standard software version (MXU-M-2.0), operators will be comfortable with what they already know. The OmniScan Weld software user interface provides access to parameters using three menu levels. The illustration to the right indicates the elements of the navigation syntax used to select menus, submenus, and parameter buttons, and to enter or select parameter values (
Menu > Submenu > Parameter = Value).
The order in which the menu items, submenus, and parameter buttons appear corresponds to their typical sequence of usage.
Conventional UT Flaw Detector Features
Many of the features typically found in conventional UT flaw detectors have been provided by the new MXU-M-2.1 Weld software, giving operators all the same functionality as conventional UT flaw detectors available on the market (for example, the Epoch XT) through the conventional UT channel of the OmniScan M.
- ADT - (Advanced DAC/TCG)
- ASME , ASME-3, JIS, custom curves
- Readings related to gates and curves measurements:
A%Curve, Max%Curve, AdBCurve, MaxdBCurve
- Onboard DGS/AVG
- ERS reading (equivalent reflector size)
- AWS D1.1/D1.5
- AWS rejection critera reading (AWS D)
- AWS class reading (AWS CL)
- API 5UE
- Crack height reading (API-DL)
- Half-wave reading (API-HW)
Advantages of Phased Array Imaging
Using phased array imaging is an improved way of visualizing what are in fact the same signals as those obtained using conventional UT. Improved imaging becomes possible simply by color encoding the A-scan signals. Why not apply the advantages of phased array imaging to conventional flaw detector sizing methods? This is exactly what we have done for you! All the sizing curve types and readings available in UT mode are also available in PA mode:
- ADT (Advanced DAC/TCG) phased array
- Onboard DGS/AVG phased array
- AWS D1.1/D1.5 phased array
Phased array software developments allow crack sizing to be performed the same way as with conventional UT-but phased array technology brings these added advantages:
- FASTER speed of inspection
- BETTER probability of detection
- REPORTING and traceability
- ONE phased array PROBE for all angles
Simplified Phased Array Interpretation
The intuitive RayTracing™ feature simplifies phased array interpretation for manual weld inspection and dramatically reduces the training time required for the operator. RayTracing is an embedded software tool that allows the weld area covered by your phased array configuration to be visualized in real time. RayTracing is therefore useful to help the operator to localize defects during analysis and can make phased array testing for manual weld inspection much simpler.
RayTracing in Setup Mode
In Setup mode, RayTracing is presented by way of an interactive wizard displaying the part, the weld, and the zone covered by the focal law configuration.
RayTracing in Inspection Mode
In Inspection mode, using the A-S-R layout, a RayTracing view helps the operator to localize the position of a defect in the weld. Also, a weld overlay on S-scans allows an indication in the S-scan to be linked with the weld position. In addition, a RayTracing operating mode allows access to the the RayTracing view parameters and easy modification of these parameters during inspection (for example: index offset, skew, weld zoom, leg quantity).
RayTracing in Analysis Mode
In Analysis mode, a table of indications can be used to record the information for each defect detected in the S-scan. For each table entry, a color point is added on the RayTracing view. This image can then be used to create easy-to-understand reports.
Phased Array Weld Probe Series
As a world leader in PA probe manufacturing, Olympus NDT has once again proved its superior applications knowledge with the introduction of its all new Weld Probe Series. Addressing multiple opportunities for improvement, this new series raises our best-selling A1 and A2 probes to a new level. Every aspect of the probes has been examined and optimized for more inspection possibilities and a more ergonomic design. The smaller housing and wedge footprint allow closer access to the feature being
inspected for a better beam coverage. In addition, the improved ergonomics makes the probe more comfortable to hold during manual inspection.
Because of its affordable price and simplicity of use, the OmniScan M is ideally suited for manual weld inspections. To perform a single-channel scan inspection, the best probes in the phased array
Weld Probe Series (WPS) to use with the M instrument are the following:
Of course, the advanced OmniScan MX modules can also be used for manual inspections, even though they offer more advanced features. In fact, the advanced modules have the significant advantages of allowing more elements for the probe aperture and a multiple-channel scan inspection. The following two probes maximize the OmniScan MX module capabilities:
