Effect of Laser Positioning on the Microstructure and Properties of NiTi-Copper Dissimilar Laser Welds
Abstract
Dissimilar pulsed laser welding of 400-μm NiTi and Cu wires was used to investigate the effect of laser positioning on NiTi-Cu joint performance. Laser positioning was found to have a significant role in the microstructure due to the difference in mixing patterns and composition distributions. Homogenous element distribution was observed in both the NiTi offset and the centerline joints, while complex mixing patterns were observed in the Cu …
