摘要:
A diaphragm bellows includes a spiral-wound, pre-profiled metal strip having neighboring turns which are connected by a continuous welding seam in an area of an outer diameter or inner diameter of the metal strip. Neighboring flanks of the metal strip enter a region of the welding seam at an angle of less than 60°.
