Abstract
The invention is directed to a metal gasket for sealing a clearance between a pair of clamping members. The metal gasket is formed of a metallic base plate on which at least one opening is defined. An annular metallic shim is welded on the base plate around the opening thereof. The annular metallic shim is disposed around the opening, and welded on the base plate by spot welding, forming a plurality of nuggets in series around the shim in such a manner that two adjacent nuggets overlaps each other and a space between those two nuggets is smaller than a diameter of each nugget.
