- Abstract
To address the limitations of existing surface cleaning technologies in shipyards, various studies are underway to apply the laser cleaning process, which uses a laser as a heat source, to pretreatment for painting and welding. Accordingly, this study conducted a cleaning experiment that uses a low power Q-switching fiber laser to remove the primer and oxide layer from the surface of steel for shipbuilding. To enhance the field applicability, this study derived the optimal laser cleaning process parameters that satisfy pretreatment standards. The main process parameters include scan speed and energy density. The most thoroughly cleaned surface was obtained at a scan speed corresponding to laser beam overlap rate of 20 % and an energy density of 10.5 J/cm2, and the working time was also significantly reduced. Therefore, this study is expected to be highly useful as important data for applying laser cleaning technology, which is receiving greater attention across many industries in addition to the shipbuilding and marine industry.
