Title:
WIRE FEEDING SYSTEM AND WELDING SYSTEM
Document Type and Number:
Japanese Patent JP2019181474
Kind Code:
A
Abstract:
To provide a wire feeding system that suppresses generation of buckling of a welding wire when increasing feeding speed of the welding wire in push-pull feeding, and to provide a welding system comprising said wire feeding system.SOLUTION: A wire feeding system of a welding system A1 includes: a feed part 21 which feeds a welding wire B according to drive of a feed motor 211; a feed part 31 which is disposed on a feeding direction side of the welding wire B according to the feed part 21, in order to feed the welding wire B according to drive of a feed motor 311; and control parts 11, 22 and 32 which control rotational speed of the feed motor 211 on the basis of a speed command S, and control rotational speed of the feed motor 311 on the basis of a speed command S. The control part 11 changes the speed command Sto an excess command value for increasing the rotational speed of the feed motor 311 according to a target command value that is a target, when increasing the feeding speed of the welding wire B, and subsequently, changes to the target command value.SELECTED DRAWING: Figure 2
