Problems solved by technology

[0004] However, since welding itself is a kind of work that generates large heat energy, and when the temperature of the outside world or inside the welding machine changes, the welding machine's own components age, the components are damaged and replaced, or the connectors between the equipment are oxidized, it will cause current and voltage. Acquisition error
In the analog control welding system of the prior art, the deviation caused by the above reasons has little influence on the output result; but in the full digital welding system with high precision control, especially the system using more delicate waveform control, the above influence It will have a serious adverse effect on the welding performance, making the welding consistency worse, the stability lower, and the welding seam shape uneven

Abstract

The application discloses a method, device and system for controlling a welding machine, and relates to the technical field of welding control. The method includes: obtaining correction parameters when the welding machine is on standby; obtaining the working current, working voltage and working temperature of the welding machine when the welding machine is working; calculating the correction current and correction voltage; and controlling the operation of the welding machine according to the correction current and the correction voltage. The method, device and system for controlling a welding machine disclosed in this application can improve the consistency and stability of welding.

Description

technical field [0001] The present invention relates to the technical field of welding control, and in particular, to a method, a device and a system for controlling a welding machine. Background technique [0002] As an important means of industrial manufacturing, welding has always played an important role in my country's economic construction. The welding process automation system can form a simple automatic welding machine, and its main components are as follows: 1. Welding power source. 2. Wire feeder and its control and speed regulation system. 3. The welding head uses its moving mechanism. 4. Weldment moving or displacement mechanism. 5, the main controller. 6. Computer software. 7. Welding head guiding or tracking mechanism. 8. Auxiliary devices. [0003] Among them, the main controller. Also known as the system controller, it is mainly used for the linkage control of each component, the control of the welding program, the setting, adjustment and display of t...
