Title:
消耗電極式アーク溶接方法及び装置
Document Type and Number:
Japanese Patent JP4940449
Kind Code:
B2
Abstract:
The present invention provides simple and inexpensive welding method and apparatus adapted to extremely reduce spatters occurring and scattering during a welding operation, even in a welding operation carried out at not lower than substantially 2 m/min. The consumable electrode type arc welding apparatus according to the present invention is provided with a welding power source 23 for controlling a welding current and a welding voltage, a unit 25 for feeding a welding wire to a base metal, a unit 26 for giving the welding wire feeding unit 25 an instruction to feed the welding wire, on the basis of a signal from a short-circuiting/short-circuiting cancellation detector 29, a welding condition setter 24, a welding speed setter 27, a unit 28 for moving a welding torch in accordance with the welding speed, and the short-circuiting/short-circuiting cancellation detector 29. The welding method according to the present invention is adapted to carry out a welding operation by feeding a welding wire to a material to be welded, and generating an arc between the material to be welded and welding wire, in which the welding is done with the welding wire feeding speed increased and reduced during the welding operation, the welding wire feeding speed being reduced after the occurrence of short-circuiting is detected, the welding wire feeding speed being increased after the cancellation of the short-circuiting and the transfer of the welding operation to the formation of the arc are detected.
