Robotic inspection by Phased-Array Ultrasound and TOFD is widely used and known. They are “robots” that drive the “scanners” with the heads in the areas to be investigated.
Now, Grupo Araujo Engenharia makes this tool available in Brazil. This procedure avoids scaffolding, which is costly, time-consuming, and exposes a large amount of Hh to the risks of confined spaces for scaffolding, surface preparation, and inspection, including using power tools.
However, there is a problem. If it is necessary to prepare the surface for exams, how would professionals reach the areas of interest? The Hh of exposure to the risk of confined spaces using electrical devices would also not be eliminated… What would be the advantage of robotic inspection if there would be a need to assemble scaffolding for access?
The answer is to robotize surface preparation as well.A project requested by Braskem UNIB 2 RS, together with Grupo Araujo Engenharia, allowed the development and application of a “cleaning robot” , which is already operational and approved for use in the field. It is now possible to prepare surface and run non-destructive scans and inspection, without assembling scaffolding and minimal exposure to the risks of confined spaces. In storage spheres, the robot is capable of cleaning welds at a productivity of 1.5 meters/minute.
