| Abstract: | Aiming at the poor weldability of the medium-carbon high strength steel 42CrMo and the e, haracteristics of the gear shaft, the welding rod j107Cr which has a lower mechanical property than the base metal is used. The heat-affected zone is preheated entirely to 400℃ before welding in an attempt of slowing down the eooling speed of the welding joint. In the process of welding, the temperature is maintained at 350± 20℃,and after welding, the stress of the gear shaft was relieved by annealing. |
