Problems solved by technology

In this case, due to the long distance of the welding wire conveying path, the driving of the welding wire needs to overcome the large frictional resistance in the path. At this time, only relying on the push motor at the source of the welding wire cannot achieve stable wire feeding

Abstract

The present disclosure provides a multi-motor wire feeding control system and method. The multi-motor wire feeding control system includes: a plurality of wire feeding units, each wire feeding unit includes a motor, a speed sensor, a current sensor and a wire feeding driving mechanism, and the speed sensor is used to detect the speed signal of the motor, so The current sensor is used to detect the current signal of the motor, wherein, the motors of each wire feeding unit have their own speed loops, and the speed loops of each wire feeding unit operate according to the same speed command, and among the multiple wire feeding units At least part of the motors have their own current loops, and at least part of the current loops in the current loops are associated with the motor current of their own wire feeding unit and the motor current of at least one other wire feeding unit; the controller, the controller according to the speed instruction 1. The speed signal fed back by each speed sensor and the current signal fed back by each current sensor control the motors of each wire feeding unit to run at a constant speed.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular, to a multi-motor wire feeding control system and method. Background technique [0002] Welding, as a very common joining process, plays an important role in industrial production and manufacturing. Welding wire is a wire welding material used as a filler metal or as a conductive wire during welding. Used as a filler metal during welding or as a wire welding material for electrical conductivity. In gas welding and gas tungsten arc welding, the wire is used as the filler metal; in submerged arc welding, electroslag welding, and other gas-tungsten arc welding, the wire is both the filler metal and the conductive electrode. [0003] In the welding construction, the welding wire is generally transported to the front end of the welding torch by a motor for welding. But in some occasions, such as shipbuilding, special vehicles and other industries, the location of the welding...
