PURPOSE:To increase the efficiency in welding work by fitting the upper electrode to the piston rod of a pressure cylinder and by fixing the lower electrode to the tip of the 1st C shaped york, further, by arranging an intermediate electrode to the tip of the 2nd C shaped york. CONSTITUTION:The upper electrode 1 is fitted to the piston rod 7 of pressure cylinder 6 and the 1st and 2nd C shaped yorks 9, 11 which are vertically movable are respectively arranged as well. Moreover, the lower electrode 2 is fixed to the tip of the 1st york 9 and intermediate electrodes 3, 4 are fitted to the tip of the 2nd york 11. In case of welding the upper part flange F1 with the upper electrode 1 and intermediate electrode 3, the welding is performed between the electrodes 1, 3 via the descent of the piston rod 7 and ascent of the york 11 with the operation of the pressure cylinder 6 and cylinder 10. The welding of the lower part flange F2 is performed via the vertical movement of the york 9, 11. Due to the interference of the intermediate electrodes 3, 4 and work W3 being prevented the work efficiency in welding is increased. |
