Transforming plant maintenance with laser cleaning
If you have seen clips of lasers removing rust on YouTube you probably found them quite compelling to watch – it’s almost hard to believe. Read on as we de-mystify laser cleaning technology and give you a sense of where it can be a helpful option for plant maintenance. Portable lasers have only recently become commercially available as a tool for surface cleaning of rust, oxides, and films such as grease and oil. A focused beam of light vaporises the surface contaminants while leaving the main substrate such as steel, aluminium or stone intact. The laser can remove paints but it does depend on the paint colour and type of coating. There are different power and optical patterns that influence how the laser performs. Lasers are well suited to heavier castings but can transfer some heat into the substrate so care is required on thinner surfaces. Heat transfer can be managed by adjusting the power of the laser and how quickly it tracks across the item. The package of equipment required for laser cleaning easily fits within a van and can be wheeled into site relatively easily. The laser is a hand-held gun at the end of a long flexible hose which makes it versatile within a variety of spaces. Relative to other cleaning options the laser is very safe to use with only ventilation, laser safety glasses and gloves required during operation. A helpful aspect of the laser is light conforms to the surface where it is pointed making it a lot easier to clean complex shapes with a lot of angles and curves. Importantly laser cleaning minimises secondary effects associated some surface cleaning options. There is no blast media or chemical residue to contend with. The vaporised contaminants are simply captured by a vacuum system alongside the laser […]
