Resumen
The friction rotary welding (FRW) is a solid state
material welding method that is able to weld not only similar but
dissimilar materials as well. The FRW allows the union between
two pieces of metal converting mechanical energy into thermal
welding. The friction generated by the rotational momentum
between the two surfaces generates enough heat to fuse the
materials without reaching the fusion temperature, this
mechanical connection can be done through atomic diffusion. The
equipment needed to perform the FRW process needed a new
control system. This paper presents the development of this new
control system through a top-down approach based on successive
refinement using modeling tools developed to model dynamic
systems to discrete events. The result presented in this paper is the
control system algorithm in Enhanced Mark Flow Graph, a high
level Petri Net derivative and a systematic to map the model in C++
in order to use it in a PIC microcontroller.
