Abstract
Peripheral sections of two diaphragms are stacked on each other. The peripheral sections of the two diaphragms form an outer rim of a diaphragm damper. The outer rim is continuously sealed and joined by laser welding over the entire circumference of the outer rim. The thickness of the tip of the outer rim is set in correspondence with the spot diameter of a laser beam at the tip of the outer rim. A weld bead is formed by welding in the entire area of the tip of the outer rim.
