Study Into Laser Spot Welding Of Multi And Single Core Wires

The present study investigates the mechanical properties (tensile testing) of the laser spot welding of single and multi core wires. In order to investigate the effect of wire diameter on the welding, three different sizes of wire were selected. It is found that at some power intensities the mechanical properties of the welds improve. In addition, a mathematical model for a nonconduction limited welding was introduced.
