Abstract

The invention discloses a method of a plasma arc welding process and motion centralized control system. A GUC-EtherCAT multi-axis motion controller is used as a control system core, a servo motor and a stepping motor are respectively used as a welding motion control unit and a welding process control unit, and carry out control through a matched servo motor driver and an Ethercat stepping motor driver; a plasma arc welding process and motion centralized control system is designed for a special welding machine. According to the system, a special plasma arc welding machine and a rectangular coordinate system robot are used as carriers, and the process control of the special welding machine and the motion control of the rectangular coordinate system robot are integrated into a GUC-EtherCAT multi-axis controller for unified control, so that a whole set of plasma arc welding control system is integrated. Compared with the prior art, the method has the advantages that the defect that welding process control and motion control are independent is overcome, the welding process control and the motion control can work cooperatively, and complex field wiring can be effectively reduced when a PLC control box is used for control.

Description

technical field [0001] The invention belongs to the field of welding control systems, and relates to a method for a plasma arc welding process and a centralized motion control system. Background technique [0002] In recent years, my country has made great progress in the field of automatic welding technology, and automatic welding technology has been widely used in various industries. For production-oriented enterprises, automatic welding technology greatly reduces the number of labor and has great advantages in reducing enterprise costs. At the same time, the application of automatic welding technology overcomes many unfavorable factors in production and is suitable for large-scale industrial product production [1] . [0003] The technical level of welding automation equipment is an important manifestation of the national scientific and technological level, and directly determines the technical level of the country's major core equipment. At present, my country's weldin...
