Paper Title:
Effect of Welding Sequence on Deposition Geometry Control in GMAW Remanufacturing
  Abstract

GMAW welding remanufacturing is the process to form part layer by layer, that it is typical nonlinear transient heat conduction. During remanufacturing, parts undergo heating time after time that the thermal cycle fluctuates acutely and the distribution of temperature gradient is complex. And welding sequence is of significant for remanufacturing accuracy control. This paper has studied the effect of three typical welding sequences (sequential welding, spacing welding and end to end welding) on the deposition geometry control in GMAW remanufacturing, combining numerical with real-time identification. The comparison shows that the simulation results are in accordance with the actual data, which verified the valid of finite element model. From the analysis, it is found that the deformation of end to end welding is the least, and then is the sequential welding and the spacing welding is the largest.
