Abstract

The invention discloses a gas control system for welding, a gas control method for the gas control system and a welding system. The gas control system for welding comprises a control device, a safetyrelief device, a first pressure sensor, a flow regulating and controlling device, a second pressure sensor and a flow sensor, wherein the input end of the safety relief device is connected with a gassource; the output end of the safety relief device is connected with the input end of the flow regulating and controlling device; the output end of the flow regulating and controlling device is connected with the gas supply end of welding equipment; the first pressure sensor is arranged on a gas path between the safety relief device and the flow regulating and controlling device; the second pressure sensor and the flow sensor are arranged on a gas path between the flow regulating and controlling device and the welding equipment; and the control device is respectively and electrically connectedwith the flow regulating and controlling device, the first pressure sensor, the second pressure sensor, the flow sensor and the signal output end of a current sensor for collecting welding current ofthe welding equipment. The gas control system, the gas control method and the welding system disclosed by the invention realize the gas saving effect by dynamically regulating the flow of protectivegases, so that the utilization rate of energy is improved.

Description

technical field [0001] The invention relates to the technical field of electric welding, in particular to a gas control system for welding, a control method thereof, and a welding system. Background technique [0002] Robots are widely used in automobiles, motorcycles, construction machinery, railway locomotives, aerospace, boilers and other industries because of their advantages such as stable quality, improved working conditions for workers, high production efficiency, and high reliability. According to the welding method used in welding-related robot operations, welding robots can be divided into spot welding robots, arc welding robots, friction stir welding robots, plasma cutting robots, laser welding robots and other types. [0003] In the prior art, the welding robot adopts the gas-shielded welding method. During welding, the welding place is protected and isolated by the shielding gas to prevent the welding place from being oxidized and causing poor welding. The commo...
