The present disclosure relates to an arc welding control method and device, and welding equipment. The arc welding control method includes: at a first moment, controlling the current to increase until it reaches a first peak value, and the first peak value lasts until a second moment; At the second moment, the control current decreases from the first peak value until it reaches the second peak value, and the second peak value lasts until the third moment; at the third moment, the control current increases from the second peak value until reaches a third peak value, and the third peak value lasts until a fourth moment; at the fourth moment, the control current drops from the third peak value until it reaches a base value, and the base value is smaller than the second peak value; The first moment, the second moment, the third moment and the fourth moment are all within one pulse period.
Description
technical field [0001] The present disclosure relates to the field of welding technology, in particular, to an arc welding control method and device, and welding equipment. Background technique [0002] With the development and progress of technology, the requirements for product quality in the industrial field are getting higher and higher, and the same is true in the welding field, especially in terms of welding spatter and appearance forming, high quality must still be maintained under the premise of high-speed welding. [0003] At present, welding has entered the era of waveform control. In related technologies, the pulsed arc welding wire with waveform control has poor consistency in droplet size and viscosity after melting. This will lead to the occurrence of multiple pulses and one drop or multiple drops in one pulse during the transition process, and the confusion of molten droplet transfer will lead to the occurrence of short-circuit bursting, which in turn will gen...
