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 invention provides a multi-motor wire feeding control system and method. The multi-motor wire feeding control system comprises a plurality of wire feeding units and a controller; each wire feeding unit comprises a motor, a speed sensor, an electric current sensor and a wire feeding drive mechanism; the speed sensors are used for detecting speed signals of the motors, the electric current sensors are used for detecting electric current signals of the motors, each motor of the corresponding wire feeding unit is provided with a speed ring of the corresponding motor, and the speed rings of all the wire feeding units operate according to the same speed instruction; at least part of the motors in the multiple wire feeding units are provided with electric current rings, and at least part of the electric current rings in the electric current rings are associated with the motor electric currents of the corresponding wire feeding units and the motor electric currents of other at least one wire feeding unit; and the controller controls the motors of all the wire feeding units to perform constant-speed operation according to the speed instruction, the speed signals fed back by all the speed sensors and the electric current signals fed back by all the electric current sensors. By means of the multi-motor wire feeding control system and method, stable wire feeding can be achieved.

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...
