Abstract
PURPOSE: To avoid a furned cap and an insufficient welding by energizing to the parallel electrodes making each opposite roller electrode two pararrel roller electrodes and by turning and sealing a cass.
CONSTITUTION: When a seam weld case 2 is fixed to a turning board and a cap 4 is positioned to a seam frame and a switch is turned on, two parallel roller electrodes 5 go down and the turning board with a push of the cap 4 and these two roller electrodes begin to be energized. Because short and long areas and corners of the cap are pressurized and always touched to the roll section of the roller electrode 5 while the turning board is turning, sealing is conducted not different from that of a round seam weld case. And due to a short distance between the roller electrode no influence of increased resistance is made and the burned cap and insufficient welding are avoided.
