| description | Disclosed is a laser melting and coating method for a hydraulic upright post for mining, which comprises: forming a spiral scan along the surface of a moving pillar of the upright post body (1) by a laser beam and a nickel-based alloy powder stream outputted from a powder feeder, the laser beam being a rectangular light spot of 15-20 mm x 1.5-2.5 mm, the line speed of the laser beam scanning being set at 480-720 mm/min, the output power being set at 7200-7400w, and the nickel-based alloy powder outputted from the powder feeder being set to contain 0.15% C, 0.5-1.0% Si, 0.4-0.8% Mn, 17.5-19.5% Cr, 21-25% Ni by weight with the remainder being Fe. Also provided is a hydraulic upright post for mining processed by the above method, wherein on the moving pillar of the upright post body (1) a laser melting and coating layer (2) having a thickness of 0.4-0.7 mm is provided.
