Document Type and Number:
Japanese Patent JP3083318
Kind Code:
B2
Abstract:
A method of multispot-welding enabling secure welding in a short period of time even when a large number of spots to be welded are present. A roughly cylindrical base body is formed by stacking flat plates and corrugated plates alternately and coiling them together. Contact points between a flat plate and a corrugated one are spots to be welded and exist numerously. An electrode facing one end surface of the base body is arranged at a predetermined distance from said end surface. Afterward, electric current is intermittently impressed on the space between the electrode and said end surface of the base body so as to generate intermittent electric discharge therebetween and to cause melt-welding at spots on the flat plates and corrugated plates to be welded. When employing such method as above, no other operation than intermittent discharge is required for enabling secure welding of a plurality of spots in a short period of time.
