Abstract Scope |
With the developing of laser technologies, precise controlling and delivering of laser energy at specific locations of different materials enables engineers to fabricate ever smaller components or devices to meet practical application requirements. Scaling down the laser welding process from macro to micro/nano regime require not only proper heat management but also rethinking of some fundamental issues when laser interacts with materials at small scales. This talk will introduce some recent works done in the Centre for Advanced Materials Joining (CAMJ) covering from microwelding to nanojoining, including laser microwelding of NiTi/stainless steel wires for medical, laser nanojoining of metal oxide nanowires and laser writing for electronic applications. Specifically, pulsed (ms, ns, fs) and cw lasers are selected for different joining processes; the processing and metallurgical characteristics of similar and dissimilar joints will be discussed. |
