Problems solved by technology

When the voltage is less than the synergistic voltage, a short circuit will inevitably occur, which will cause the molten pool to oscillate, which in turn will cause problems such as arc instability and arc length changes.

Abstract

The invention provides a welding control method, a welding machine control device and a welding machine. The welding control method comprises the steps that after a welding pulse is output, whether ashort circuit occurs in a current pulse period or not is detected; when the short circuit is detected, a short circuit duration and an arcing duration are obtained; a filtering voltage calculation method is determined according to the ratio of the short-circuit duration to the arcing duration; and the filtering voltage of the welding pulse is calculated in real time according to the calculation method, and when the filtering voltage reaches the preset voltage, next welding pulse is output. According to the embodiment of the invention, the problems of unstable arc and inconsistent arc length caused by short circuit in the welding process can be avoided.

Description

technical field [0001] The present disclosure relates to the technical field of electric welding machine control devices, and in particular, relates to a welding control method capable of overcoming inconsistencies in arc length and arc instability caused by short circuits, and a welding machine control device and welding machine applying the control method. Background technique [0002] With the development of welding technology, in order to improve production efficiency, MIG / MAW is more and more used in actual welding operations. In order to ensure the welding quality and avoid welding defects such as undercut and poor forming, the technical requirement is to keep the arc stable and the arc length consistent during the welding process of MIGMAW. [0003] When using melting electrode pulse gas shielded welding for welding operations, it is first necessary to adjust the appropriate current and voltage to match the welding workpiece. When the voltage is lower than the synerg...
