The challenges of many medical device manufacturing applications are pushing the need for more sophisticated metals-joining technologies. In response to these demands, laser welding has become an important enabling technology, as single-use medical devices become smaller and smaller and as demand grows and reliability requirements tighten for implantable cardiac health management device. The use of laser welding is also making practical a wider range of applications as a newly available laser light wavelength opens the door to reliable laser welding of copper and gold alloys. This article highlights motion and laser control techniques beneficial to hermetic laser seam welding of implantable devices, and new metals joining production methods made possible by the availability of “green light” (532nm) pulsed welding lasers.
