Path planning for MIG surfacing of robot-based remanufacturing system

摘要

Robot-based remanufacturing system can scan the worn parts and develop the corresponding models,compare them with the standard model,calculate the weld deposit,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 aspects are contained:introducing the planning principle,selecting the suitable welding process based on welding parameters(current and speed),calculating welding overlap quantity by the superposition method.Also,it has been verified that good weld profile can be obtained with the optimized parameters.
