Tungsten electrode argon arc welding process control method and system, computer equipment and application

Abstract

The invention belongs to the technical field of tungsten electrode argon arc welding processes, and discloses a tungsten electrode argon arc welding process control method and system, computer equipment and application. A controller manages a welding power source, a wire heating power source, a wire feeding motor driver, a swing motor driver, a walking motor driver and an arc voltage tracking motor driver module in a unified mode, and signal and data interaction between the controller and a subordinate controlled object is realized through a field bus. A new technical scheme is provided for welding modes, the welding modes comprise a direct-current welding mode, a low-speed pulse mode, a high-speed pulse mode, a synchronous pulse mode and a double-pulse mode, and the innovation of the welding modes is embodied in control logic and process control. The process control logics are all generated by a controller, so that process adjustment is facilitated; welding parameters are all set on a human-computer interface, so that adjustment and management are facilitated; and welding control is an organic whole and is not scattered any more, welding seam forming is attractive, and the process quality is controlled.

Description

technical field [0001] The invention belongs to the technical field of argon tungsten arc welding technology, and in particular relates to a method, system, computer equipment and application of argon tungsten arc welding process control. Background technique [0002] At present: argon tungsten arc welding is widely used. For automatic or semi-automatic argon tungsten arc welding, it includes the setting and control of welding electrical parameters, auxiliary wire filling parameters, and welding actuator control parameters. Most of the integrated solutions at home and abroad All rely on the fixed parameter setting mode of the existing equipment manufacturer, for example: the welding current pulse mode adopts the pulse output mode of the welding power source itself, the wire feeding adopts DC or pulse wire feeding, and the swing mechanism is an independent swing mechanism; during the welding process The middle controller starts the welding machine to output pulse current, the...

AI Technical Summary

Problems solved by technology

[0005] (1) The management relationship between the existing welding machine, wire feeder, and swing mechanism is not a very close organic combination, but scattered, which brings great limitations to the welding process

[0006] (2) The appearance and quality of the existing welding seam is poor and uncontrolled, and the integrity of the process parameters is not coordinated, especially in the case of swinging, the melting of the welding wire and the energy pulse of the welding current do not match, which not only causes great damage to the process debugging Troubled, while bringing great randomness and uncertainty to the process control
