[0002] When repairing single arm beam by metal laser additive technology, first, the defects of single arm beam, such as oblique crack and block, need to be mechanically pretreated to eliminate residual cracks and surface corrosion products. This step is usually completed by using handheld electric polishing tool, but this method has the problems of low efficiency and high labor intensity. Since the online repair of single arm beam must be completed within limited maintenance time, improving operation efficiency is crucial for the promotion of technology.
