In recent years, advanced techniques and higher functions are needed for industrial products. Welding different metals (ex; aluminum and titanium) is an important technique. The physical properties of them are quite different, so the welding them is difficult. Additionally, ductility of intermetallic compound is very low, so it should be prevented. In this research, laser welding method was studied. Especially, aluminum alloy and titanium were welded with high power laser diode. Using microscope and EPMA, the welding mechanism of aluminum alloy and titanium by this method can be considered that aluminum is mechanically mixed into interface with titanium. Mechanical welding was obtained without production of itermetallic compound.
