joint of Al-Cu by controlling the welding heat input. The welding joint is composed of fusion zone of the aluminum side, the weld zone and brazing zone of the copper side which is divided into two parts.... The tensile strength of joint firstly increases, and then decreases with the increase of welding heat input. When the wettability of wire and aluminum on the copper is good, and the thickness of IMC......
