Abstract
A technique facilitates joining of components without subsequent heat treatments. The components are joined by using a friction stir process which establishes a desired friction stir region at an appropriate location to securely join the desired components. In well applications, various components of sand screen assemblies may be joined by the friction stir process. For example, metal sand screen components may be securely coupled with a corresponding metal base pipe. The joining technique enables retention of the corrosion resistant properties of the materials without applying post weld heat treatments and/or other subsequent treatments.
