Welded bellows are manufactured by stamping sheets of metal

into diaphragms and welding the inside and outside edges of

them. Welded bellows are remarkable in that any metal can

be manufactured into bellows if it can be welded. An

especially remarkable feature is that the number of

convolutions is theoretically unlimited. The bellows are

manufactured to have excellent elasticity and bendability,

while retaining high hermeticity in a manufacturing process

that requires outstanding technology. Welded bellows are

attracting attention as a high-performance part which

supports the semiconductor, liquid crystal, nuclear power,

medical device and other high-tech industries.
