Summary of the technology This technology relates to a waveform control method for GMA high speed welding.
This technology of a waveform control method for GMA high speed welding, wherein the control of waveform for high speed welding accompanying short-circuit transfer by alternately generating the short-circuit and arc phenomena, comprises a first control step of guiding the rapid solution of the short-circuit by keeping the current rising gradient of the 150~300 A/ms welding current during the short-circuit; a second control step of delaying 8~12ms after the arc is generated by the afore said first control step; and a third control step of guiding the short-circuit by reducing 40~60A current after the time delay by the afore said second control step.
