Abstract

The embodiment of the invention provides a control system of laser parameters in a double-beam laser welding system. The control system comprises human-computer interaction equipment, a processor and a plurality of ET200S units. The human-computer interaction equipment is used for receiving set parameters and displaying the state of the system. The processor generates a first control instruction and a second control instruction according to the set parameters, wherein the first control instruction is used for controlling the laser parameters and the second control instruction is used for controlling the motion state of a robot. All the ET200S units are connected with the processor through a bus, the ET200S unit connected with a laser is used for sending he first control instruction to the laser and obtaining a first feedback signal form the laser. The ET200S unit connected with the robot is used for sending the second control instruction to the robot and obtaining a second feedback signal from the robot. The control system of the laser parameters in the double-beam laser welding system meets the requirements for double-beam laser welding during complex element machining, and therefore the quality and the efficiency of double-beam laser welding can be improved easily.

Description

technical field [0001] The invention relates to the technical field of double-beam laser welding, in particular to a control system for laser parameters in a double-beam laser welding system. Background technique [0002] Double-beam laser welding is a new welding process developed in recent years. A typical double-beam laser welding system generally consists of two robots and two fiber lasers, such as figure 1 As shown, due to the use of two laser beams to weld the "T" joint on both sides at the same time, the thermal deformation on both sides of the joint offsets each other, effectively controls the deformation during the welding process, and improves the performance of the parts, making double beam laser welding in aviation. and other fields have been widely used. [0003] During the double-beam laser welding process, the parameters of the laser are set by the control computer of the laser itself, and the robot controls the laser on and off through the switch.
