Path Planning for MIG Surfacing of Remanufacturing System via Robot

摘要

Remanufacturing system via robot can scan the worn machine parts and gain the model of them, compare with the standard model, calculate the amount to be welded, implement welding path planning, and repair the worn parts with MIG surfacing automatically. This paper investigates the welding path planning after calibrating, scanning and model rebuilding. The following issues are contained: introducing the planning principle, selecting the suitable welding process based on welding parameters (mainly current and speed here), calculating the amount of bead-lap by the method of superposition. Also, it has been verified in theory that the result is good for welding.
