Title:
WELDING CONTROL DEVICE AND WELDING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/199784
Kind Code:
A1
Abstract:
Provided is a welding control device capable of improving production efficiency and welding quality. One aspect of the present disclosure provides a welding control device used for a resistance welding machine comprising: a first electrode and a second electrode; a support part that supports the second electrode; a motor that moves the first electrode relative to the second electrode; and an encoder that outputs the amount of rotation of the motor. The welding control device comprises: a strain sensor that measures the strain of the support part; and a control unit that controls the resistance welding machine. The control unit has: a displacement amount detection unit that detects, during the execution of welding by the resistance welding machine, the amount of displacement of an inter-electrode distance between the first electrode and the second electrode on the basis of the amount of rotation of the motor output by the encoder and the strain of the support part output by the strain sensor; and an adjustment unit that adjusts, during the execution of the welding, a welding current of the resistance welding machine on the basis of the amount of the displacement.
