This study investigates the effectiveness of using a 3 kW rotary continuous-wave laser transmitter for removing salt from severely corroded steel surfaces. It proposes an improved surface treatment flow that includes laser treatment as a pre-treatment step. This study focuses on severely corroded weathering steel with artificial corrosion pits that require painting after surface treatment to prevent corrosion under the film. This study demonstrates that the laser can effectively remove salt during the rust removal process, and the proposed surface treatment flow can prevent the re-corrosion of more than 5 % of the treated surface area in high-temperature, high-humidity environments for one week, providing a quality surface for paint coating. This study suggests that laser surface treatment can be used as a pretreatment step for abrasive blasting and should be further explored and promoted in engineering applications.
