Abstract
The invention discloses a control method and system for short arc pulse welding, and the method comprises the steps: in a welding process, adjusting the wire feeding speed of a current period based on the position of a droplet transition short circuit moment in a previous pulse period; the method specifically comprises the steps that if the molten drop transition short-circuit moment in the previous pulse period is within the pulse mid-value current or pulse base value current time period, the wire feeding speed is kept unchanged in the current pulse period; if the droplet transition short-circuit moment in the previous pulse period is before the pulse median current period, reducing the wire feeding speed in the current period; and if no short circuit state exists in the molten drop transition in the previous pulse period, the wire feeding speed is increased in the current period. According to the invention, droplet transition can stably present a transition form combining pulse transition and short-circuit transition, welding heat input can be reduced, stable welding can still be realized under the condition of high welding speed, and the welding efficiency is improved.
