TH164215B - Resistance spot welding equipment, composite electrode And resistance point welding method - Google Patents

Abstract

Resistance capacitive welding equipment for high speed spot welding operations Resistors on a set of discs (1) that include a number of overlapped metal plates (2A, 2B) will include a pair. Of composite electrodes (10,20) facing each other to hold the pad assembly (1) between A composite electrode (10,20), each of which includes Rod-shaped electrodes (11,22) with tip surfaces to be brought in contact with and pressed against the plate assembly (1); A rigid object leading to the sky (12,22) with a through hole (12b, 22b) where the electrode (11,21) is inserted and which has a tip surface to be exposed. With and pressed against the sheet set (1) and the resonable assembly (13,23) that are coupled to the end The back of a rigid object (12,22), a resonable assembly (13,23) that has been shaped to provide pressure to the Rigid body (12,22) When the electrode (11,21) and the rigid body (12,22) are pressed against the plate set (1), it is therefore possible to expand the appropriate current range. And to strengthen the welding joints:
