Welded Bellows

Welded bellows (also called edge-welded or diaphragm bellows) are highly flexible.These are manufactured by welding a number of individually formed diaphragms to each other both in the ID and OD.

The welding of metal bellows is a microscopic welding process, typically performed under laboratory conditions at high magnification.

Material Used

Welded bellows can be fabricated from a variety of exotic metals and alloys like AM 350,15-5,17-4 Carpenter steel, etc.


Advantages of welded bellows include compactness(higher performance in a smaller package), ability to be compressed to solid height with no damage, resistance to nicks and dents, and dramatically greater flexibility.
