Repair of Broken Output Shaft of Precision Planetary Reducer
Due to the large carbon equivalent of No. 45 steel, the hardening tendency of the heat-affected zone is relatively large during welding, and cold cracks are prone to occur, and the welding amount of the shaft is large, so there is inevitably a large welding deformation and welding stress. In order to reduce welding deformation and improve weld quality, preheating measures before welding are taken,
