    Service lives of steel bridges are limited by corrosion. Coating is commonly applied to steel structures in order to prevent corrosion. In recent years, a laser cleaning treatment is introduced as a new technique for surface preparation of steel structures. However, the influence of laser cleaning on fatigue life of welded joint is unknown. In this study, fatigue tests were conducted on as-welded and laser-treated out-of-plane gusset joints. The test results showed that the laser cleaning treatment only had little influence on fatigue strength of out-of-plane gusset welded joints.
