General Applications

Power Generation - Wind Towers
Used to check fit-up of tower sections before welding to ensure joint offset and gap are within tolerance. After welding checks are made for height, width, toe angle, undercut and offset.

Construction and Mining
Used to check part fit-up on critical underbody, boom and crawler components subject to fatigue loading as well as final weld quality.

Used to check new models for conformance of fit-up and welds to design requirements. Also used to tune in welding parameters for robots doing mast and frame productions.

Transportation - Railroad
Used to check fit-up and welds for fatigue sensitive areas on locomotive chassis. Also used on tanker cars to check fit-up and weld quality.

Defense / Military
Used to check weld quality for both steel and aluminum components for tanks and personnel carriers. Also used in conjunction with design engineers to determine weld size required to achieve performance required.

Used to check fit-up and weld quality of inner structures for wings and fuselage. The material is titanium and welds are small and difficult to manually inspect consistently so the Wiki-SCAN is very helpful in this situation.

Used for laser welded blanks to tune in tooling during first piece setup to achieve required weld quality. Also used by Tier 1's to do auditing of visual weld quality per OEM requirements.

Used to inspect girders / I-beams welded using Submerged Arc Welding to ensure AWS D1.1 weld quality is achieved. Also used to ensure welds are the right size so distortion is minimized. Finally, used to check the setup so the weld is dialed in correctly before a single structure is completed.

Tubes & Pipe
Used to assess setup of a tube mill to ensure joint preparation is within tolerance and to ensure welding process is tuned in correctly.

Tank & Vessel
Used to optimize the weld quality for different tanks types and across several stations making the same parts. Key features can be measured and compared to the perfect weld to ensure every weld is within acceptance tolerances.

Used for training welders to assist them in learning faster how to manipulate the arc to meet requirements for different processes and weld positions. Can be used to give specific grades so that the subjectivity of the instructor is eliminated.

R&D Welding Labs
Used for weld procedure development by insuring joint fit-up meets the requirements of the welding code being used. Also used to measure weld quality features to provide feedback to welding process changes in parameters, wire type, gas mixture, etc.

Frequently Asked Questions

1. Is the WiKi-SCAN limited to only inspecting to specific standards?
No, the WiKi-SCAN™ can inspect to any standard, for example AWS D1.1, ASME, etc. Tolerance limits can be manually set for any code being inspected for.

2. What type of joints can the WiKi-SCAN inspect?
T-Joint, Butt Joint and Lap Joint.

3. What type of welds can the system inspect?
Filet Weld, Groove Weld and Lap Weld.

4. What is the smallest defect that can be detected?
0.5 mm

5. What is the maximum inspection speed?
The inspection speed depends on the actual spacing between each scan that you need. As a general reference, a defect of 1 mm in length can be detected at a speed of 1 m/min, with or without encoder.

6. How many scans can I save on the WiKi-SCAN?
The on-board memory can safely hold around 4000 scans depending on if they include images, video and/or audio comments.

7. What happens if the WiKi-SCAN battery goes dead?
All scans and joint info are automatically saved so, in the event of a dead battery, there is no loss of information. The system also features a “Hot Swap” feature that allows for a quick change of batteries without the need to shut down the system.

8. Can one measure non-weld features?
Yes, the manual measurement software allows a user to measure non-weld features from the 3D profile and the 2D picture.

9. How far can one inspect?
The dynamic scan mode records and categorizes up to 100 weld discontinuities down the length of a weld. The amount of weld that can be scanned at one time is dependent on quality of the weld and rigidity of the tolerance limits.

10. Can the WiKi-SCAN inspect the inside of a weld?
No, the WiKi-SCAN™ only does weld surface geometry measurements and inspections.

11. Are all inspections and measurements automatically saved?
Yes, all inspections are automatically saved and can be transferred via USB or Wi-Fi.

12. Does one have to transfer the result to a PC in order to see them?
No, the results are available for viewing directly on the WiKi-SCAN™ screen.

13. Is the WiKi-SCAN pre-calibrated?
Yes, the WiKi-SCAN™ is pre-calibrated at SERVO-ROBOT and can be validated using the verification block that comes with every system. The frequency of the verification procedure is dependent on the user quality assurance plan.

14. Is there a warranty on the WiKi-SCAN?
Yes, there is a one year warranty.

15. How does one identify a weld so it can be found later and related to a specific location on
the part?
Each scan can be tagged with a date and time stamp, the name of the inspector, the part serial number, weld number, and individual scan number. There is also a picture taken with each scan that can help an inspector locate the scan location.

16. Can someone make undesired changes to the set tolerance limits?
The WiKi-SCAN™ comes with one level of password protection that blocks out the ability to change any tolerance limits or system information.

17. Is the WiKi-SCAN laser safe?
Yes, the laser class is 2M. The eyes’ natural blink reflex is good enough to protect the eyes from this laser class. However, users should not look directly into the laser for extended periods of time or utilize optics that could concentrate the beam into the eyes.
18. Is it safe to use the WiKi-SCAN in hot environments?
Yes, the WiKi-SCAN™ is rated for ambient temperatures up to 110 degrees F. As the device does not come in contact with any surface during the inspection, there is no limit to the temperature of the weld being inspected. This gives inspectors a safe way to inspect welds that are still red hot.

19. How durable is the WiKi-SCAN?
The WiKi-SCAN™ is extremely durable and has passed military grade drop tests. It comes with a protective rubber covering and features replaceable screen protectors.

20. Does the WiKi-SCANTM require any additional computer software?
No, each inspection report can be transferred and saved as a custom Microsoft Excel spreadsheet. A free Excel viewer software is available from Microsoft. Although it is not required, additional computer software is available to allow a user to add or change system features from a computer and load it into the WiKi-SCAN™.

21. How do I receive system updates for my WiKi-SCAN?
Contact your local SERVO-ROBOT sales representative. Upon request, the latest software can be made available via FTP site or sent through the mail on a USB.

22. Can the WiKi-SCAN be mounted on a robot?
Yes, please contact a SERVO-ROBOT representative and ask about the WiKi-ROBO™.

23. How do I set the percentage (%) over welding?
Percentage (%) over welding is based on the minimum tolerance of the left and right leg size. The minimum tolerance must be correctly set for the specific joint being scanned to obtain accurate results.

24. What is the difference between leg size and leg length?
Leg length is the distance from the theoretical root to the weld toe. Leg size is the amount of leg that contributes to strength. These differences are most apparent in concave welds.

25. How long does the battery last?
The WiKi-SCAN™ comes with 2 batteries and they last about 2 hours each with heavy use.

26. Can I remove the encoder for tight fitting areas?
Yes, the WiKi-SCAN™ encoder can be removed if needed and used without.

27. Can the encoder be retrofitted?
Yes, it is possible to add the encoder after having purchased the system.

28. Can I purchase a non-standard joints package after receiving a WiKi-SCAN with only the
basic joint package?
Yes. These can be purchased later and can be downloaded through the USB.

29. Why didn’t my WiKi-SCAN recognize the software package update?
The WiKi-SCAN™ update package must be located directly on the USB; it cannot be located in a folder.

30. For inspection reports, is there a maximum number of input characters?
Yes, the maximum characters for task name is 100, for user ID is 12 and for Part ID / Weld ID / Acquisition ID is 16. There is no limit for comments.
