Etude du soudage TIG de l’alliage d’aluminium 2024-T3
TypeCommunications avec actes
Recent programs of aircraft design are characterized in terms of materials, by introducing weldable alloys as alternatives to the traditional technique of riveting, open the way to reduce weight and allow cost reductions in production and maintenance. Understanding the influence of various parameters of TIG welding process applied to the alloy 2024-T3 aluminum should help us to take into account the behavior in service of assemblies, from the design of structures. This work deals with the definition of a weldability operating field of the alloy studied and metallurgical and mechanical consequences of this assembly on the properties of the material.

Microstructural and Mechanical Characterization of the Yb: YAG Laser Welding of High-Pressure Die-Casting Mg-Al-Mn Magnesium Alloy OUALLAM, Seddik; MASSE, Jean-Eric; PEYRE, Patrice; DJEGHLAL, Lamine; GUITTONNEAU, Fabrice; BOUTAGHOU, Zoheir; KABA, Liamine (Trans Tech Publications Ltd, 2020)In this work, the Yb:YAG laser beam welding of the magnesium alloy AM60 was studied. A laser power of 2 kW and a welding speed of 3.5 m / min give a different welding quality than that obtained by CO2 laser with the same ...
Texture evolution in Nd:YAG-laser welds of AZ31 magnesium alloy hot rolled sheets and its influence on mechanical properties COMMIN, Loreleï; DUMONT, Myriam; ROTINAT, René; PIERRON, Fabrice; MASSE, Jean-Eric; BARRALLIER, Laurent (Elsevier, 2011)AZ31 hot rolled magnesium alloy presents a strong basal texture. Using laser beam welding (LBW) as a joining process induces high temperature gradients leading to major texture changes. EBSD was used to study the texture ...
BELHADJ, Asma; MASSE, Jean-Eric; BARRALLIER, Laurent; BOUHAFS, Mahmoud; BESSROUR, Jamel (Laser Institute of America, 2010)Magnesium alloys have a 33% lower density than aluminum alloys, whereas they exhibit the same mechanical characteristics. Their application increases in many economic sectors, in particular, in aeronautic and automotive ...
Residual stress evolution analysis in AZ31 friction stir welds using X-Ray and neutron diffraction COMMIN, Loreleï; BARRALLIER, Laurent; MASSE, Jean-Eric (JCPDS - International Centre for Diffraction Data, 2009)The challenges of weight reduction in aerospace industry have drawn considerable interest in magnesium alloys technologies. Assessing the efficiency of new joining techniques, as Friction Stir Welding (FSW) is then required. ...
