Soudage homogène MIG de l'alliage d'aluminium 6061

Abstract

The homogeneous welding (same filler metal as base metal) of the 6061 aluminium alloy with MIG process has never been reported in the open access literature. This work shows that the CMT (Cold Metal Transfer) MIG, a derivative of MIG, allows producing welds without hot-cracking. Moreover, further heat treatments partially increased or fully restore the mechanical properties of the weld. These results are compared with 6061 heterogeneous welds usually met in the industry. © Owned by the authors, published by EDP Sciences, 2013.
