Journal ArticleDOI
Dissimilar material joining using laser (aluminum to steel using zinc-based filler wire)
Alexandre Mathieu,Rajashekar Shabadi,Alexis Deschamps,Michel Suéry,Simone Matteï,Dominique Grevey,Eugen Cicala +6 more
TL;DR: In this article, a statistical approach for an overlap assembly configuration using a filler wire composed of 85% Zn and 15% Al is presented, and the fracture mechanisms of the joints are analyzed by a detailed characterization of the seams.
Journal ArticleDOI
Laser brazing of a steel/aluminium assembly with hot filler wire (88% Al, 12% Si)
Alexandre Mathieu,Sébastien Pontevicci,Jean-Claude Viala,Eugen Cicala,Simone Matteï,Dominique Grevey +5 more
TL;DR: In this article, a feasibility study for steel/aluminium assemblies with filler wire of 88% Al and 12% Si was conducted, to see how the mechanical performance of such joints could be improved.
Journal ArticleDOI
Temperature control in laser brazing of a steel/aluminium assembly using thermographic measurements
TL;DR: Kreimeyer et al. as mentioned in this paper showed how thermography may be used to control temperature during laser braze welding, which was shown that if the layer is less than 10 μm thick, the joint is not compromised.
Journal ArticleDOI
Effects of the powder, laser parameters and surface conditions on the molten pool formation in the selective laser melting of IN718
TL;DR: In this article, a series of single-track selective laser melting (SLM) experiments was carried out on IN718 plates with and without a powder layer and with different laser processing parameters (power and scan velocity) and surface conditions (original surface and sand blasted surface).
Journal ArticleDOI
The numerical simulation of heat transfer during a hybrid laser–MIG welding using equivalent heat source approach
Issam Bendaoud,Simone Matteï,Eugen Cicala,Iryna Tomashchuk,Henri Andrzejewski,Pierre Sallamand,Alexandre Mathieu,Fréderic Bouchaud +7 more
TL;DR: In this paper, a numerical simulation of an industrial case of hybrid laser-MIG welding of high-thick duplex steel UR2507Cu with Y-shaped chamfer geometry is presented.
