Abstract

Laser pressure welding of dissimilar metal aluminum and copper can be realized at high welding speed. The microstructural evolution of the weld are characterized by using scanning electron microscope (SEM) and transmission electron microscopy (TEM). The investigation results indicate that the weld mainly consists of four zones, namely (I) the fusion zone between the aluminum base metal and the interface is mainly the Al solid solution and Al-Cu eutectic alloy; (ii) the interface zone between the copper and the fusion zone mainly composes of Al-Cu eutectic alloy and the intermetallic compounds (IMCs), such as Al2Cu and Al2Cu3; and (iii) the base metal of aluminum and copper.
