Title Study on the mechanism and control system of hybrid sources friction stud welding
Abstract
In view of the present hybrid sources friction stud welding technology, design welding technology and process, launch simulation test of friction stud welding process, and research on hybrid sources friction stud welding experiment device and control system. This topic uses induction heat and friction heat source on the basis of composite, depends on hybrid sources friction stud welding technical requirement, control mode and process are obtained, combined with simulation test of friction stud welding process, put forward the general design scheme of equipment, and the design of the hydraulic system and electric control system. The basic principle of the hydraulic system are correct, it can provide friction pressure and upset pressure required in friction stud welding process, and satisfy the welding platform action requirements; electrical control system uses PLC as the control core, by which the hydraulic pump, the servo motor, the induction power supply are opened and closed, the system is initialized, and the motion process of the hydraulic system is under control, the control procedures are simple and reliable.
Keywords: induction friction composite heat source stud welding, simulation of friction stud welding process, PLC control
