Abstract：

In order to improve the service life of crankshaft mold and reduce the cost of remanufacturing, an automatic additive manufacturing process of arc fuse welding and forging composite was proposed, and the corresponding software and hardware systems were developed. Then, the additive target model of crankshaft mold was sliced in layers and planned in tracks, and the hammering track and welding track were overlapped so that each weld seam was hammered after welding in this process. The hammering analysis shows that the hammering after welding can correct the residual tensile stress of the weld seam to residual compressive stress and improve the mechanical properties of the welding seam. In the automatic additive manufacturing process, the mold is added conformally, while the manual repair of mold adopts the full welding process, so the automatic additive manufacturing process can greatly save more than 50% of material and reduce the welding time by more than 50%. After serving 8000 pieces, the collapse area and collapse amount of the automatic-repair mold are significantly less than that of the manual-repair mold, and in addition, the amount of surface micro-cracks is also greatly reduced, which greatly improves the service life of mold.
