Abstract
PURPOSE: To prevent a differential pressure chamber from being exposed to the atmosphere and obtain the weld zone of high quality by opening the transfer inlet and outlet for the welding works of the differential pressure chamber in a vacuum conveying chamber built therein with a conveyor.
CONSTITUTION: The welding works 2 are placed by a pusher 20 on a conveyor 8 moving in a vacuum conveying chamber 13. When the welding works 2 are conveyed to the transfer inlet and outlet 7 for the welding works, they are held on the index table 3 in a differential pressure chamber 4 by a chucking mechanism 10. During their stay in this vacuum conveying chamber 13, the moisture and gas adsorbed on the surface of the welding works 2 are released. The steam, etc., in the atmospheric air sucked into the vacuum conveying chamber 13 through the transfer inlet 18 are also released. Hence, a stable degree of vacuum is obtained in the differential pressure chamber without receiving any adverse influence thereof. The welding works 2 held on the index table 3 is moved up to the welding position by a driving unit 12, where they are welded by the 1st driving unit 6 and an electron beam welding head 1.
