A Simulative Method for Studying the Bonding Condition of Friction Stir Extrusion

In the manufacturing industry, problem related to management of metal waste is considerable importance, since it produced in large quantities during mechanical processing.However, its recovery not always a simple task, especially with regard cutting processes. fact, due presence surface oxide and contaminating oily residues, process these components often very expensive polluting. This can be solved FSE process, patented 1993 by The Welding Institute. counted among main innovative processing techniques developed Industry 4.0, as involves only scraps coming from machining processes starting material, without providing for their preliminary re-melting billet form, uses heat generated friction between tool metal. Since quite recent development simulative models useful understanding basic mechanisms. objective this research analyze if how bonding phenomena occour considering both thermal stress conditions involved parameters.As result, FEM analysis proved valid correctly forecast really take place parameters affect quality. Moreover, was possible confirm that Piwnik Plata model good criterion predicting effects technology.
