Abstract
PURPOSE: To let welding be repeated under preset constant work sandwiching pressure by providing lower and upper electrodes to the elevating frame part and the supporting part vertically movable to this, respectively and pressure-contacting both electrodes to both surfaces of the work always under constant working pressure.
CONSTITUTION: A head frame 3 consists of an elevating frame part 31 and a channel-shape frame 32 below this. The former is elevatably supported by the unit frame 2 supported to the welding machine frame and is held in the lower position in a normal state. The upper electrode 51 of a welding head 5 is vertically movably supported to the front face of the frame part 31 and a lower electrode 52 is fixed onto the moving axial line of the electrode 51 at the front end of the lower arm member of the frame 32. At the welding, the welding unit U is horizontally moved, after which a cylinder 4 contracts and pressure-contacts the electrode 52 to the bottom surface of the work W under the specified working pressure P1. Next, the cylinder 53 elongates and pressure-contacts the electrode 51 to the top surface of the work under the specified working pressure P2, whereby welding is done. Thereby, the welding conditions may be made constant even if the work is of three-dimensionally intricate shapes.
