Abstract

An arc welding control method performs welding of a work by alternately repeating a short-circuit period for short-circuiting a welding wire to a work and an arc period for regenerating an arc to perform arc discharge. The control is performed so that the welding output current immediately after regeneration of the arc is maintained higher than the welding output current immediately before the arc regeneration for a predetermined period of time.

Description

technical field [0001] The present invention relates to a consumable electrode type arc welding machine and an arc welding control method which generate an arc between an electrode composed of a consumable electrode and a base metal or weldment to be welded, thereby welding the base metal and control welding output. Background technique [0002] In an arc welder, when the generation of sputtering increases, vaporized metal adheres to the base metal, deteriorating welding quality. Also, when sputtering is generated beyond an allowable frequency, it is necessary to correct the operation of the welded portion. If such correction is impossible, weldments having such welded portions must be discarded, which reduces the efficiency of the welding operation and greatly deteriorates the price-performance ratio. [0003] Conventionally, various methods have been proposed in which sputtering is reduced to thereby reduce the number of steps for correcting welded portions. For example...
