  • Salvaging damaged shafts The Fabricator

    Considering RepairWelding ConsiderationsRestoring DimensionsA Special Welding RepairManagement should provide all available information about the shaft, including the original drawing of the part, to the person in charge of the maintenance and repair facility What is the material? What are the treatments and the hardness? Was the part casehardened? This information is essential if welding is being considered as a possible repair process If this information is not available, it would be wise to seek the help of a metallurgical laboratory before planning the repair procedure An informative, qualitative a
