From the pressed diaphragms to convolutions to the finished artilcle
The solid length of a welded bellows is not much more than the total thickness of all the diaphragms used plus a small design allowance.The Male and Female diaphragms are first welded together at their inside diameters to form a welded pair or convolution. The convolutions are then welded together at their outside diameters to form the Bellows. By leak checking the finished Bellows on a Mass Spectrometer and taking weld measurements during production it is possible to produce a bellows with high integrity welds equal to the most demanding applications.
