[Abstract]:In order to reduce energy consumption in arc welding process and reduce environmental emissions, the optimization of energy saving and high efficiency process parameters in arc welding process was studied. The electric energy consumption objective function and thermal efficiency objective function of arc welding process are established. On the basis of considering welding quality and equipment and equivalent practical constraints of process, the welding current and welding speed are taken as optimization variables. A multi-objective optimization model with minimum energy consumption (energy saving) and maximum thermal efficiency (efficient) as the optimization objective is proposed, and the adaptive evolutionary gradient niche genetic algorithm is used to solve the model. The feasibility and effectiveness of the proposed model and method are verified by an example of manual arc welding for a seat sealing surface. The results of optimization are compared with those of the actual results and the results of the traditional genetic algorithm (GA).
