Research on Electrophysical Characteristics of Plasma Arc in CO2
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 5
Abstract
A brief analytical review of research papers on the processes of arc welding was made. Conclusion on the relevance of the research in the field of synthesis of welding process control systems and the use of automatic systems was made. To implement the control processes, empirical studies of the current-voltage characteristics of the arc were performed to determine the parameters that could be considered as the parameters of the automatic control system. The experiments were performed to study the current-voltage characteristics of a compressed plasma-arc when C02 is used as plasma gas. Different torch schemes were used in the experiments. Forms of the current-voltage characteristics were examined. A conclusion was made that the parameters to control the welding process should be carried out with respect to a set of parameters, i.e. it should be vectorial. Accurate analytical models of welding processes are impossible to obtain, therefore, the methods of the fuzzy set theory are used, the decision models and the theory of possibilities that should be applied to formalize the welding parameters and the construction of the control system should be performed in the form of a hybrid control system.
