Caracterización de soldadura de materiales disímiles Cu - acero-AISI 304 obtenidos del proceso de soldadura por fricción.

Abstract

Nowadays, industry is looking for continuous improvement in existing manufacturing processes, including welding processes to improve efficiency, economic return and process speed. Among the methods that have great advances is the friction welding, whose importance in the aerospace, automotive, among others, has grown because of the ease with which it can be used both in the union of equal materials as dissimilar. This document shows the procedure performed to determine the feasibility of welding by this method stainless steel AISI 304 and electrolytic copper. For this a series of tests can be carried out according to the appropriate standards, a test that allows to alter the basic parameters of this method: forging pressure, preheating temperature and rotation speed, in order to determine the characteristics of the joint and show if it can be seen a welded joint. Proving that under the conditions existing in the Welding Laboratory of the National Polytechnic School, it is not possible to carry out the welding of these materials.
