Summary:Robotic arc welding represents one of the most important industrial applications. After handling applications, arc welding is the most common industrial application, totaling over 66,000 new robotic cell installations by 2020 [1]. For this reason, in the development of new robotic cells two approaches may be of interest at present: the use of a pre-designed robotic cell and the development of a customized robotic cell for arc welding. Discussion on this issue regarding the involved advantages and disadvantages of each approach and conclusions are presented in the first part of the paper. The second part of the paper deals with a specific computational algorithm developed for the optimal selection of the engine of industrial robots. The specific steps of the calculation procedure detailed in the paper can be used for a large number of models of industrial robots used for arc welding or other industrial application. The application of the calculus procedure is exemplified in the paper on the optimum selection of the driving motors for the last three NC axis of an ABB MB 2400 articulated arm industrial robot, but still the algorithm can be extended to the optimal sizing and selection of all IR driving motors. The computational algorithm can also be used for other IR models that have a similar design of the final effect orientation subsystem. The algorithm was intensively tested for many industrial robot models, and the calculation results were validated for all IR analyzed models.
