Traditional methods of inspecting stress points in welded joints of power generating equipment often involves using abrasives or blasting. This poses a problem because it can change the shape of the metal surfaces. When this occurs, inspectors have a hard time figuring out if the changes occurred as a result of the testing process or because of stress defect.
Our laser technology allows for Non-Destructive Evaluation (NDE) to occur with the best inspection results possible. Inspect stress points of pipes or turbines without altering the surface of the substrate and expose bare metals without abrasives. Laser cleaning also makes it easier to see cracks from stress defects that are sometimes missed due to surface changes created by blasting.
- Does not drive debris into cracks or fold metal over small indications
- Quickly de-paints / cleans welds to expose very fine cracks and indications better than any other method
- Eliminates blasting grit clean-up time and expense
- Enables inspector to closely follow the laser cleaning process and inspect welds as the work is being done
