Abstract
Structural elements of weld guns are made of composites for strength, low weight and long life. Anisotropic strength structures are fabricated by making a hollow form and applying layers of carbon fabric and unidirectional tape which are aligned with the forces developed within the structure to withstand shear, tension and compression. A tough abrasion resistant fabric such as an aramid fabric is applied as a protective covering. A resin binder unites the composite structure.
