| Abstract: | Since the bearing hole of the bottom body of the slurry pump transmission box casting had too big internal diameter and caused no machining allowance,it was repaired by using the welding process.Based on the analysis of the welding property of the casting material,it was decided to adopt the surfacing welding to repair the casting.The repairing process was introduced.The repaired casting met the requirement of the bearing assembly. |
