High Quality Metal Bellows and Metal Bellows Assemblies

Weldmac, a leading manufacturer of precision sheet metal and machined and welded assemblies, has expanded its in house capabilities to include bellows and expansion joints. Weldmac is now offering an aerospace-quality, custom-designed metal bellows. We now offer these high quality metal bellows to companies in Aerospace, Defense, manufacturing, food processing, refinery, power generation, water treatment, mining and other industries.

Invention Out of Necessity
It was necessity that drove Weldmac to enter the commercial market for bellows. WeldmacMetal Bellows Stacked Up needed specialized bellows assemblies for its own manufacturing processes. There was no product on the market that met our high internal standards. We then set out to apply our philosophy and approach to research and create metal bellows to the highest possible standards.

Capabilities
Current facilities are capable of constructing metal bellows in sizes of 100 or more inches in diameter. Because Weldmac has the highest-level quality control and process certifications, its bellows far exceed the usual commercial standards. Our bellows are manufactured to meet the requirements of the aerospace industry. This means they last longer and perform better, with a wide range of materials to meet high temperatMetal Bellowsures and have excellent corrosive properties.

The rigorous standards of Weldmac quality requires unique instrumentation such as micro processors, sensors and digital read out. Weldmac has set out to produce a product that exceeds most quality requirements regardless of the application. Our CNC approach to this manufacturing process has resulted in a higher quality, tighter tolerance, more repeatable product for our customers. We offer the same standard for our hydro-formed bellows. Everything is CNC controlled including internal pressures, feed rates and dwell time.

There is virtually no requirement we cannot meet

Weldmac holds the following certifications and approvals:

  • American Society of Mechanical Engineers (ASME)
  • AS9100 C, ISO 9001:2008
  • Nadcap approved
Metal Bellows

Experience
Because of our four decades of experience in forming metal, adding metal bellows and metal expansion joints to the family of capability has been a smooth transition. The bellows capability has been launched utilizing Weldmac's design and build of all necessary equipment.

Whether you require a punched and rolled bellow or a hydro-formed bellow, Weldmac has the capability to meet your requirements. Our vast internal capability allows Weldmac to provide our customers with a top quality finished assembly no matter the complexity or material composition.
