Abstract
PURPOSE: Seam welding equipment, enable to surely weld even when error is made in the accuracy of work establishment, by fixing the work and carrying out ON.OFF control of welding current by either contacting the electrode with the work or not.
CONSTITUTION: The work 2 composed of the main frame 3 of semiconductive element to be sealed, such as flat package type IC etc., is fixed on the work stand 1. The roller electrode 4 is contacted with the work 2 by the driving device 6. Welding current is put in through the switch 8 detecting by the microswitch 7. When a desired seam welding is ended and the electrode 4 is slipped from the work 2, the switch 8 is made OFF and the welding current is cut off. By the above mechanism, unsealing or spark generation is avoided by the lag of ON.OFF timing of welding current and a superior seam welding is able to carry out.
