dc.description.abstract A 4kW CW Nd:YAG laser was used for lap welding of three different dissimilar sheet metal combinations, namely 316L S/S - Ti64, 316L S/S - Al 5251 and Al 1200 – Cu (99.85%). A welding matrix of laser power, travel speed and spot sizes was investigated in order to determine the operating windows for the specific set-up. Sound lap welds could be obtained with the Al/Cu and SS/Al dissimilar combinations, but only within narrow operating windows. Extremely hard phases were obtained within the fusion zones, especially in the SS/Ti welds, resulting in very brittle welds which were prone to cracking. en
