Vibration Effects on Weld Bead Characteristic of FV520B Stainless Steel Remanufactured with Surfacing Deposition Technology
The surfacing deposition forming method was adopted for the remanufacturing experiment execution of the FV520B precipitation-hardening stainless steel. The “pull-push” model of the weld pool solidification was simultaneously built to research the effects of vibration on the characteristics of the weld bead formation. The results demonstrated that the form factor of the weld was decreased to a certain degree, due to the addition of vibration. Along with the vibration frequency increase, the weld reinforcement coefficient increased firstly and subsequently decreased. When the vibration frequency was f = 1500 r/min, the weld bead with the maximum reinforcement coefficient and relatively low form factor was acquired, which was suitable for the surfacing deposition execution for the steel remanufacturing.
