Laser beam welding of dissimilar sheet metal
\r\ncombinations such as Ti\/Al, SS\/Al and Cu\/Al are increasingly
\r\ndemanded due to high energy densities with less fusion and heat
\r\naffected zones. A good weld joint strength involves combinations of
\r\ndissimilar metals and the formation of solid solution in the weld pool.
\r\nMany metal pairs suffer from significant intermetallic phase
\r\nformation during welding which greatly reduces their strength. The
\r\nthree different sheet metal mentioned above is critically reviewed and
\r\nphase diagram for the combinations are given. The aim of this study
\r\nis to develop an efficient metal combinations and the influence on
\r\ntheir interfacial characteristics. For that the following parameters
\r\nsuch as weld geometry, residual distortion, micro hardness,
\r\nmicrostructure and mechanical properties are analyzed
\r\nsystematically.<\/p>\r\n","references":"[1] M. Kreimeyer. F. Wagner, and F. Vollertsen, Optics and Lasers in\r\nEngineering (2005).43, 9.\r\n[2] E. Anawa., O. M. Elmabrouk, and A.
