The disclosure relates to the field of welding technology, in particular to a melting pole pulse gas shielded welding machine, an energy control device and an energy control method for the melting pole pulse gas shielded welding machine. The energy control method includes: obtaining the initial pulse waveform parameters before welding of the melting pole pulse gas shielded welding machine; judging whether a short circuit occurs in the first pulse period when the melting pole pulse gas shielded welding machine is welding; When a short circuit occurs, record the short circuit duration in the first pulse period, and judge the short circuit mode based on the initial pulse waveform parameters and short circuit duration; adjust the initial pulse waveform parameters according to different short circuit modes to adjust the melting electrode pulse gas shielded welding machine The pulsed arc energy in the second pulse period, which is adjacent to the first pulse period. The energy control method can improve arc stability in welding, not only reduces the generation of welding spatter, but also improves the adaptability of the melting electrode pulse gas shielded welding machine to welding wire and base metal.
Description
Technical field [0001] Technical Field The present disclosure relates to welding, and particularly to a gas-pulsed MIG welding, melt free energy pulse of gas welding power control apparatus and a control method. Background technique [0002] With the development of welding technology, welding becomes diverse, more and more welding automation and intelligent. Since the pulse MIG welding process gas welding having stability, less spatter and less loss of material, etc., so that the consumable electrode pulse is applied more and more widely gas welding. [0003] Currently, in the pulse MIG welding process of gas welding, the welding wire due to the influence of the brand and the base material, sometimes caused by an arc short circuit state unstable situation, which the weld puddle vigorous shaking, to produce splash, seriously affect the weld. [0004] Thus, the need to provide a melt free energy pulse gas welding control method. [0005] The above information disclosed in this Back...
