Abstract The mechanical characteristics of dissimilar Al-Cu connections, joined by a novel, robust laser braze-welding process are reported. A ber laser is used in combination with a 2D galvoscanner to provide spatial power modulation by superposed circular beam oscillation. With the help of statistical experimental design, a broad range of processing parameters has been inves- tigated in order to understand their e ects on the joint characteristics. A maximum shear strength of 121 MPa has been detected within the scope of the experiments. [less ▲]
