Study of 6061 weld heat affected zones made with GMAW
Résumé
6xxx aluminum alloys are widely used in the industry for their properties such as mechanical properties, corrosion resistance, weldability or good formability. Among the 6xxx aluminum alloys, the 6061 is one of the alloys most employed for structural application and is commonly welded. Welding is a joining operation which impairs base metal because of the high heat input used. It creates a zone where mechanical properties are different from the base metal which is called heat affected zone (HAZ). In the 6xxx aluminum alloy the HAZ is softer than base metal.
