This paper reviews a groundbreaking laser technology and standardizations for social implementation, which offers a novel approach to surface treatment for steel structures such as bridges. Maintenance process involves removing old paint, rust, and salt deposits that lead to corrosion. A new laser surface treatment method employing high-power CW (continuous wave) lasers has been developed, offering an effective solution for salt removal.
