The steps of robotic execution
(Robotic surface treatment generally follows the same processes and standards as with conventional, manual execution)
1. Fresh water cleaning if required
Standard pressure washing nozzle integrated on the robot.
2. Pre inspection and documentation
Video documentation of surface and specific findings. Dry film thickness for reference before abrasive blasting.
3. Surface cleaning (abrasive blasting or water jetting).
Selected nozzles attached. Working pressure at nozzle end verified. Abrasives chosen according to paint specification. After finished abrasive blasting the robot is applied in dust cleaning by air-only blasting of surface and then finally vacuuming before dust cleanliness verification by testing.
4. Inspection and documentation of clean surface before painting
Clean surface inspection and documentation. Surface profile, cleanliness, relative humidity and temperature checked and documented. Test for salt consentration perfomed.
5. Painting
Correct nozzle size and spread selected. Speed and overlap is tested and speed conversion tables utilized for securing the correct nominal coating thickness.
6. Inspection of surface after painting
Robot operator monitors the paint work in progress through real time video. Critical points such as weld seams and edges are exercised while equipment is still active. Inspection at this point is of non-contact to surface.
7. Data collection (coating thickness, wall thickness, etc)
After curing of coating the data collection starts with dry film thickness measurements. Data is presented in tables and graphics.
