Record UT Weld Indication Coordinates Clearly

A UT report should distinguish sound path, depth below a defined surface, projected surface distance and position along the weld. These quantities are related in an examination geometry, but they are not interchangeable labels. A number followed by millimeters does not tell the recipient which quantity it represents. Use explicit column headings and preserve the instrument or reviewed calculation reference. Do not relabel a displayed sound path as indication depth simply because the client’s form has only one distance field.

Begin by identifying the physical question the coordinate needs to answer. A reviewer may need to locate the indication in the weld, compare two observations or plan an authorized follow-up. Those uses require context beyond the numerical value. The ultrasonic testing method page provides broader method context. This worksheet focuses on the reporting relationship between the acquired observation, the coordinate convention and the physical location, rather than teaching an examination or sizing technique.

Record the origin used for position along the weld and the positive direction of travel. Use the actual drawing, component feature or controlled marking specified by the project. A zero point chosen in the field needs a retrievable relationship to the physical weld. Left and right alone can be ambiguous when the recipient views the component from another side. State the viewing convention and any relevant orientation reference so another person can identify the same location after the crew has left.

Keep the datum distinct from the scanner or probe’s starting position if they are not the same. An acquisition may begin before the weld’s reporting origin or use an offset entered into the instrument. Preserve that relationship rather than assuming the first recorded sample equals weld zero. If the source does not establish the offset, identify the uncertainty before converting positions. A convenient coordinate transformation cannot supply missing physical evidence about where the examination started.

State the surface from which depth is measured and the component orientation used in the report. On a part examined from more than one side, the same numerical depth can refer to different physical locations. Do not combine values from opposite scanning surfaces under one depth heading without explaining the conversion or convention. Preserve the actual source quantity and the responsible evaluation that establishes the report’s physical reference.

If a report uses a common component coordinate system, record how each acquisition view relates to it. The transformation should be supported by the applicable geometry and reviewed process. Do not assume that subtracting a displayed depth from a nominal thickness is always the correct way to combine views. The actual part geometry, reference surface and examination setup matter. Where the relationship is unresolved, retain the separate source coordinates and raise the question rather than merging them into an apparently precise location.

A surface position may be referenced to the beam index point, the front of a wedge or another defined physical point. Record which reference applies. A probe position marked on the surface is not automatically the projected location of the indication. The report should distinguish the position of the examination assembly from the location derived for the reflector. If an offset is used, preserve the source and its meaning rather than hiding it in an unexplained corrected distance.

Evident’s curved-surface correction discussion describes instrument position calculations using setup inputs and distinguishes sound path, depth and surface distance. For reporting, retain the actual reference convention and relevant configuration. The manufacturer’s explanation does not validate your entered values or establish a universal coordinate formula for every weld geometry. A reviewer needs to know which quantity the instrument displayed and how it was related to the physical component in this examination.

An angle-beam observation can involve different propagation paths and reflections. Record the path or leg context established by the responsible interpretation where it is needed to understand the location. Do not use a simple first-path assumption for every indication. Evident’s angle-beam inspection tutorial illustrates refracted beam paths and reflection within the test piece. The reporting task is to preserve the path interpretation actually used, not to infer it from a number without the supporting examination evidence.

Keep uncertainty in path assignment visible when it affects the coordinate. A geometry response and a relevant discontinuity can require different interpretation, and a report preparer should not decide that distinction from a screenshot alone. Reference the reviewed source record and the responsible technical conclusion. If several views contribute to the location, identify their relationship. Avoid presenting one set of coordinates as an independently verified physical position when it is still a provisional interpretation awaiting the required review.

Record whether the reported coordinate relies on a flat or curved geometry treatment where that distinction is material. A circumferential examination on a tubular component can require a different position relationship from a flat-plate model. Preserve the actual part dimensions and configuration references used by the responsible process. Do not silently apply a generic trigonometry calculator to a curved or otherwise complex geometry and present the output as a validated indication location.

A geometry input should come from the appropriate source and have a clear meaning. Nominal dimensions, measured dimensions and drawing values may serve different purposes in the examination setup. The technical process determines which are applicable. Record the source rather than replacing it with a familiar nominal value after acquisition. If a geometry correction is changed during review, retain the relationship between the original display and the revised coordinate so the reader can understand why the reported position differs.

Location coordinates describe where an indication is reported; length, height or another dimension describes its interpreted extent under the applicable technique. Keep those fields distinct. A sound path is not an indication length, and a depth coordinate is not automatically through-wall height. Use the actual sizing terminology and evidence supplied by the responsible examiner or reviewer. Do not populate a missing dimension with a position value simply because both are expressed in the same unit.

If start and end coordinates are used to describe an extent, define the axis and the basis of those endpoints. A cursor selection in one view may not represent the full physical extent without the appropriate interpretation. Preserve the source and any limitations. The worksheet does not establish a sizing rule or acceptance threshold. It organizes the information needed to understand the reported location and dimensions without allowing a reader to mistake an instrument display quantity for a different physical property.

In a fictional weld report, the source record includes a position along the weld from datum D0 and a projected surface distance from the beam index point. A draft table labels both columns Distance. The reviewer cannot tell which number locates the indication along the weld and which describes the cross-weld geometry. The preparer restores the two definitions, units and origin references. The report also identifies the scanning side and the source event used for the reviewed location.

A second observation from the opposite side is retained with its own acquisition context until the responsible reviewer establishes how the views relate. The preparer does not average the coordinates or assume that equal numbers mean the same physical point. This scenario is hypothetical and gives no calibration or coordinate calculation instruction. It demonstrates why a useful report needs meaning and reference direction alongside every position value, especially when several instrument views or scanning sides contribute to one interpreted indication.

Use units in the relevant headings or fields and check them after transfer from instrument exports or worksheets. A mixed-unit project needs an explicit conversion record where values change. Preserve the original quantity and the checked transformation when necessary. Do not assume that a numeric field copied from one report uses the same unit as the destination form. A coordinate error caused by a unit mismatch can remain visually plausible, particularly when the recipient sees only the final result table.

Where an angle is included, state the actual convention and its role in the examination record. A nominal wedge label, a refracted angle used in the setup and a geometric orientation on a drawing are not automatically the same field. Do not combine them under a generic angle heading. The responsible technical process establishes which values are relevant and verified. The report should preserve their meanings rather than treating every degree value as interchangeable input to a calculator.

If a selected screen image supports the location, identify the source data, view and relevant cursor or display context in the external package. A cropped image may omit axes, units or the scanning-side reference needed to interpret it. Keep enough context to make the image useful and preserve the unaltered source where required. Do not reconstruct missing coordinate labels from memory after the image has been separated from the instrument record.

The free report’s image upload fields are for company and client logos, not examination screenshots. Record the external image and native-data references as text, and deliver those files through the agreed package. The reporting app does not read the native ultrasonic data or verify the cursor placement. It can present the reviewed coordinate table and its source references after the responsible technical process has established what the selected view and values actually represent.

The free tools directory includes planning calculators and other utilities. Before using any calculated position, check the tool’s supported geometry, input definitions and assumptions against the actual examination. A result from a simple geometry aid should not be used outside its stated conditions or treated as a substitute for the governing procedure and reviewed instrument setup. Preserve the calculation source and responsible check if it contributes to the report.

Do not use a calculator to resolve an unidentified datum, unknown scanning side or uncertain path interpretation. Those are evidence questions, not missing arithmetic. A mathematically correct output can still locate the indication incorrectly if the input meaning is wrong. The procedure draft workspace can help organize proposed coordinate-recording responsibilities for review, but it does not approve an examination setup or validate a calculation. Keep the technical decision with the actual responsible process.

When several probes, sides or techniques observe a related indication, preserve each source event and coordinate convention. The responsible reviewer may correlate them into one reported location, but that relationship needs evidence. Do not merge records solely because the component name and approximate position appear similar. A weld can contain several nearby responses, and a repeated local indication number can refer to different events. Keep the correlation decision and its source references retrievable.

If the views disagree, record the difference and the next technical action rather than averaging coordinates to create artificial agreement. The discrepancy may concern datum, geometry, interpretation or a different physical response. The report preparer should not choose the explanation without support. A concise correlation note can preserve the issue while the detailed evidence remains in the external package. This makes the report more useful for follow-up than a single precise coordinate whose conflicting source observations have been discarded.

Before issue, select representative indications and trace their reported positions back to the weld map and source events. Include a case with a changed scanning side, a geometry correction or an offset if the assignment contains one. A simple first event may not expose errors in the more complex records. Confirm that the coordinate headings and direction conventions allow the intended recipient to locate the same region without guessing from the preparer’s interpretation.

Use the free digital reporting workspace to assemble the reviewed table, definitions and necessary notes. Check the actual PDF for readable units, signs and reference labels. Long identifiers should remain distinguishable after wrapping. The report buyer-review guide supports broader completeness checks. Here the priority is that the numerical values retain the physical meanings that made them useful in the original examination record.

If a tubular component uses clock positions, state the viewing direction and the physical feature that defines the clock origin. Looking from opposite ends reverses the apparent direction around the circumference. Keep that convention consistent in the weld map, report table and follow-up instruction. A clock position may be useful for locating a region, but it should not be silently converted into a precise circumferential distance without the required geometry and reference evidence. Preserve the actual form of the source location and identify any reviewed transformation used for the delivered report.

If a coordinate is corrected after review or distribution, identify whether the change concerns transcription, reference convention, geometry interpretation or new examination evidence. Those causes have different implications. Retain the original source and the responsible correction basis through the applicable process. Do not change the position in one table while leaving an old location in the conclusion, repair request or image index. Review the affected downstream references deliberately.

Use the worksheet below to capture the datum, quantity definitions, source event and reviewed location relationship. Replace the fictional entries with the actual project convention. A useful coordinate record does more than provide numbers: it allows another qualified person to understand where those numbers came from and how they relate to the weld. That clarity supports review and follow-up without inventing a sizing result, a physical position or a technical approval that the evidence does not establish.
