Abstract

The effect of temperature as a function of time in laser welding of similar and/or dissimilar materials was evaluated experimentally and by finite element analysis. Three cases = copper-copper, copper-aluminum, and aluminum-aluminum welded joints - were analyzed by simulation. There were four tests evaluations: tensile strength, relative impact strength, resistance versus temperature variation, and an electron microprobe analysis. Good tensile strength and low electrical resistance results were obtained for welding ETP copper with a neodymium (Nd)-glass laser. Copper-aluminum conductors responded with good tensile and impact strengths to laser welding.
