The embodiment of the invention provides a control method and device for gas metal arc welding, a medium and an electronic device. The control method for the gas metal arc welding comprises the stepsof detecting average current, peak voltage and the average value of the peak voltage in the pulse period in real time during the implementing process of the gas metal arc welding; if difference is detected between the peak voltage and the average value of the peak voltage, calculating the variation rate of the peak voltage based on the peak voltage and the average value of the peak voltage, and calculating the current bias based on preset current and the average current; and then adjusting the length of the pulse period as well as the rising slope, peak current and descending slope of the current in the pulse period based on the variation rate of the peak voltage and the current bias. According to the technical scheme in the embodiment, the control method has the advantages that the stability of the gas metal arc welding is improved, and the effect of the gas metal arc welding is ensured.
Description
technical field [0001] The present invention relates to the technical field of gas metal shielded welding, in particular to a control method, device, medium and electronic equipment for gas metal shielded welding. Background technique [0002] Pulse MIG shielded welding is more and more popular among users because of its excellent welding performance, good operability and all-position welding. However, due to the increasingly complex welding conditions, the pulse MIGA welding first needs to select the appropriate current and voltage according to the welding material, welding wire type, etc. At this time, the built-in expert data of the welding power supply (including preset current and preset Voltage, etc.) will produce an offset; at the same time, due to the shaking of the hand or the change of the welding position during manual semi-automatic welding, the dry elongation will inevitably change, which in turn will cause the arc length of the arc to change. In addition, duri...
