OmniScan SX \ MX2 Training – Phased Array Wedges Overview 

  

Phased array wedges perform the same function as conventional UT wedges by coupling sound energy from the probe to the material at the desired refracted angle and wave type. Phased array wedges come in all shapes and sizes for various applications and are an essential part of the inspection process. Phased array wedges are used to assist the probe in beam formation for shear wave and longitudinal wave inspections, just like UT. 1D Wedges typically used in OmniScan SX\MX2 applications come in 3 varieties: 1. Shear wave angle beam 2. Longitudinal wave angle beam 3. Longitudinal wave straight beam

The OmniScan MX2 part and group wizards are designed to make the task of creating, modifying, or deleting new groups fast and efficient. The software will give us step by step guidance in a logical sequence for populating the essential parameters required by the focal law calculator for beam formation. The OmniScan MX2 has a limit of 8 groups that can be a combination of phased array, conventional PE, conventional PC, or TOFD. The OmniScan XS is limited to single probe, single group inspections. The total number of A-scans or focal laws for both the OmniScan SX and MX2 cannot exceed 256. Additionally, during the wizard steps many parameters of the inspection such as the weld overlay, scanner information, probe orientation, etc. will be populated as well.

The part and weld wizard is the first of four primary wizard functions that are used to prepare an inspection or “.Ops” file in the MX2. The parameters of the part and weld wizard are common to all of the groups created. That is why it is separated from the setup and focal law wizards. The part wizard contains the following functions that are common to all groups in the setup:  – Material Thickness.  – Material. This will associate a 2 velocities to the group. 1 for shear and 1 for longitudinal.  – CSC Mode. Plate\OD\ID geometry.  – Weld Overlay creation. Weld overlays assist in analysis by superimposing an image of the weld on the data.

Each step in the wizard process is completed prior to selecting next. Each task is explained in the next series of slides. Below is the entire wizard sequence.

OmniScan SX \ MX2 Training – Part and Weld Wizard – Part Thickness. 

 

The material thickness is not directly related to the focal law formation but is necessary for the skip lines on the A-scan and S-scan, and the trigonometry readings such as DA. (Depth of signal in gate A) Material velocity and thickness are entered during the part wizard process and can also be modified in Group\Probe\Part>Part menu. Part thickness can be changed at anytime without affecting the beam or calibration.

OmniScan SX \ MX2 Training – Part and Weld Wizard – Material Velocity   

The material selection is relative to velocity and associates both the shear and longitudinal velocity for use later in the focal law section of the wizard. Use of materials that are not in the database can be entered directly in UT Settings>General>Velocity or calibrated through the velocity wizard. The velocity of the material and wedge are essential parameters for the focal law calculator and beam forming. To achieve 1 degree angle accuracy and proper beam formation the material velocity must be within +\- 50 meters per second of the real velocity. 45-70 degrees shear has < 12 meter/sec velocity deviation

OmniScan SX \ MX2 Training – Part and Weld Wizard – CSC Mode 



 

CSC (Circumferential scanning mode) is relative to the trigonometry readings such as depth (DA) and surface distance (PA). The COD inspection requires focal laws to be built with an external calculator and imported into the OmniScan SX\MX2 for use. Only plate is supported directly in the SX\MX2 setup wizard. For the purposes of the calculator, piping girth welds are treated the same as plate as the geometry is the same.

OmniScan SX \ MX2 Training – Part and Weld Wizard – Weld Overlay 



There are seven default weld types available in the wizard from which almost any weld can be created. Any of these welds can be divided into four sections: 1. 2. 3. 4.



 

Root (Size and angle) Land (Size and offset) Hot pass (Height, angle, or radius) Fill (Height and angle)

Some weld types may not require all four sections. For any section not required enter 0mm for the size or height. There are options for symmetrical and asymmetrical welds. The weld overlay on the OmniScan SX\MX2 is available on the S-scan and Bscan only.
