Title of the articleOptimization of the laser power for welding spring-twisted channel
Abstract.Today there is an active implementation of technology in laser material processing industry in Russia, and mathematical modeling significantly reduces the costs and timing of the development work. Mathematical model of the thermal process of laser welding spring-twisted channels can be used to approximate the temperature distribution in the weld and heat affected zone. The paper presents a mathematical model of a thermal cycle used to describe the process of laser welding spring-twisted channels. The graphs of thermal cycles that are based on data obtained in the experimental work. The optimization of the laser power for welding spring-twisted channels to obtain an equation for finding the optimum power. The obtained value of the laser power upon heating a thin-walled cylinder is optimum with regard to minimum deviations from the true temperature distribution at a predetermined time t'.
Keywords.Spring-twisted channel, laser welding, thermal cycle, mathematical model.
