Title:
RESISTANCE SPOT WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/139952
Kind Code:
A1
Abstract:
Provided is a resistance spot welding device capable of forming a large nugget while suppressing the occurrence of expulsion. This resistance spot welding device is a resistance spot welding device that performs welding between a pair of electrodes (4, 5) by superposing at least two steel sheets (1, 2), the resistance spot welding device comprising: said pair of electrodes (4, 5); a pressurizing force measurement device (6) that measures a pressurizing force; and a control device (7) that controls current passage between the electrodes (4, 5) on the basis of pressurization between the electrodes (4, 5) as measured by the pressurizing force measurement device (6). The control device (7) performs control such that the pressurizing force (F) after the start of current passage as measured by the pressurizing force measurement device (6) reaches a predetermined value.
