Paper Title:
Finite Element Simulation of Laser Cladding Layer Crack by Micro-Regulation Forging
  Abstract

Micro-plastic deformation is produced on the surface of the laser cladding layer by micro-forging, and crack makes a change in cladding layer. In this paper, a finite element model with a simplified panel strain model elastic-plastic of stress and strain relationship and adaptive meshing technique was used to simulate laser cladding layer crack by using DEFORM-2D software. Laser cladding process of cracks by micro-regulation forging is simulated. Comparing to the measurement of crack width, the results show that micro-forging can make the surface of laser cladding layer the residual tensile stress to adjust compressive stress, and the micro-forging can significantly reduce or eliminate the laser cladding layer crack. Reasonable and effective regulation of high-frequency micro-forging can improve the surface quality in micro-cladding layer.
