The invention relates to the technical field of welding, and provides a welding system and a welding method. The welding system comprises a welding robot, a welding gun installed on the welding robotand a welding power supply of the welding gun, the welding system further comprises a power supply sensor, a first processing module and a control module, the power supply sensor is used for detectingthe actual current / the actual voltage of the welding power supply; the first processing module is connected with the power supply sensor and used for acquiring the relationship between the actual current / the actual voltage and the theoretical current / the theoretical voltage; and the control module is used for adjusting the running speed of the welding gun or the wire feeding speed of the weldinggun based on the relationship between the actual current / the actual voltage and the theoretical current. According to the welding system, when individual parameters such as welding power supply voltage and current are suddenly changed due to circuit reasons or equipment reliability and the like, other parameters can be automatically adjusted to adapt to influence caused by parameter changes of power voltage, current and the like, so that the deviation between the welded weld joint and the designed value is relatively small, and irregular welding spots in the welding process are avoided.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a welding system and a welding method. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. Welding can be divided into manual welding and automatic welding. Manual welding is mainly that the welder holds the welding torch, observes the condition of the weld while welding, and adjusts the welding process parameters in real time according to the condition of the weld, such as welding voltage, welding current, welding wire feeding speed, welding speed and other parameters. Its main feature is flexibility, which can realize various welding. Its main disadvantages are: the labor intensity of workers is high, the working environment is poor, and occupational diseases are prone to occur; it is greatly affected by the labor s...
