Presented at ICALEO 2009
The high brightness of single mode fiber lasers provides an excellent cutting source however in welding can be detrimental to weld quality, especially for ferrous materials. For conductive materials such as aluminum and copper the use of a single mode fiber presents some clear advantages of welding speed and cost effective welding solution. The ability to a focus to a sub 25 micron spot size enables the single mode fiber las...$28.00

Presented at ICALEO 2009
Conventional laser welding speeds, on the order of millimeters per second, are not economically feasible for future energy applications such as fuel cells. A typical fuel cell stack may have hundreds of feet of weld length which must be executed with high precision and no defects, as a single defective weld could result in failure of the entire stack. Recent technological advances in both laser systems ...$28.00

Presented at ICALEO 2009
Ti-alloys used in prosthetic applications are mostly alloys initially developed for aeronautical applications, so their behavior was not optimized for medical use. A need remains to design new alloys for biomedical applications, where requirements such as biocompatibility, in-body durability, specific manufacturing ability, and cost effectiveness are considered. Materials for this applica...$28.00
