ABSTRACT: The paper presents the methods for the measurement and improvement of energy parameters and quality of high-frequency inductive steel tube welding. This improvement is shown through lessened energy and power consumption and increased weld quality. The key welding quality and energy efficiency indicators are obtained by group fuzzy analytic hierarchy process, including five experts in the assessment, based on the three groups of welding process characteristics and eleven indicators. Based on the selected key indicators and the results of the practical analysis, the new impeder with Fluxtrol magneto-dielectric material is designed and developed. The function of the impeder is to transfer and convert electromagnetic energy into heating energy in the best possible way. Practical results prove the quality and efficiency of the proposed solution.KEYWORDS: automation, fuzzy analytic hierarchy, fuzzy systems, hierarchy process, reasoning, weldingRead full text (pdf)
