Composite Aluminum-Copper Sheet Material by Friction Stir Welding and Cold Rolling

Effect of Welding Parameters on the Weldability of Material

In this study, the effect of various welding parameters on the weldability of Mild Steel specimens having dimensions 50mm× 40mm× 6 mm welded by metal arc welding were investigated. The welding current, arc voltage, welding speed, heat input rate are chosen as welding parameters. The depth of penetrations were measured for each specimen after the welding operation on closed butt joint and the ef...

Welding Parameter Optimization of Alloy Material by Friction Stir Welding using Taguchi Approach

Friction stir welding is used as a solid state joining process for soft materials such as aluminium alloys and also for hard materials like steels. It avoids many of the common problems obtained in fusion welding. In mechanical, civil, automobile, naval, and aeronautical engineering beams are widely used of the magnesium alloys for different applications and that are joined by conventional iner...

Laser welding of dissimilar aluminium alloys with filler material

Laser welding of dissimilar aluminium alloys with filler material Luís Filipe Amaro Pinto Instituto Superior Técnico – Technical University of Lisbon – Portugal September 2008 Abstract The aluminium alloys are materials with great potential because of its high strength and low weight. However, the welding of dissimilar aluminium alloys is difficult in autogeneous welding, due to these alloys ar...

Optimum composite material design

— The microstructure identification problem is treated : given certain phases in given volume fractions, how to mix them in aperiodic cell so that the effective material constants of the periodic composite lie the closest possible to certain prescribed values ? The problem is studied for the linear conduction équation. It is stated in terms of optimal con trol theory ; the admissible micro geom...
