Thermal Modelling And Simulation Of Automatic Welding System

This paper covers the development, design and simulation of an automatic real time control system applied in mechanical system of recovery of spur gears. using modern techniques of automatic welding. This automatic system permits to recover the initial geometric contour of the wheel by performing automatic welding runs across each tooth, keeping the mechanical properties intact. The thermal model that describes the process of heat transfer in the wheel under the regimen of automatic welding is defined in order to obtain the behavior of the temperature gradient in the entire wheel body. Computer simulation was carried out with experimental data. The general hardware architecture of the automatic system of recovery of the spur gear is proposed, where robotic and artificial vision systems are used.
