Szukana fraza: [Abstrakt = "Ultrasonic welding has been used in the market over the past thirty years. Very short time, low energy consumption, repeatability and lack of additional materials and operations during the connection process are key reasons for which this technology has been found advantageous in the mass production. Nevertheless the problems faced by industry regarding to ultrasonic welding are the poor weld quality and low strength of the joints surface when the welding parameters are incorrect. In this paper, the control parameters like vibration amplitude, weld pressure and weld time are considered for the welding and copper wires \(Cu\-ETP1\). Experiment is conducted according to the fractional design with replications to get the responses like tensile shear stress and T\-peel stress and weld area. Measured data are utilized to develop fuzzy logic model between responses and predictors. As a quality is an very important issue in these manufacturing industries, the optimal combinations of these parameters are found using fuzzy logic approach."]
