Shaft part damage typically includes center hole distortion, journal wear, wear on the shaft threads, shaft breakage, and the like. For repairing the shaft neck or the shaft with larger thread abrasion loss, thickened surfacing welding is usually adopted, and then a corresponding machine tool is used for processing and recovering to the design size. In order to ensure that enough machining allowance can obtain better machining quality and save consumable materials, the size of the journal after surfacing is controlled to be 3-5mm larger than the diameter of the original journal, and the weld joint is required to be continuous, uniform in forming and compact in structure. The traditional thickening surfacing welding method comprises two methods, one is that a shaft is in a static state, a welding gun (or a welding tongs) welds a first welding line along the axial direction, the length of the first welding line is the length of a wear surface needing to be repaired, then the shaft is manually turned, a second welding line is welded on the symmetrical surface of the first welding line, a third welding line is welded between the first welding line and the second welding line, and … … cycles are repeated on the symmetrical surface of the third welding line until the wear surface is fully piled.
