(UltraWELD) ULTRAfast laser WELDing of highly dissimilar materials – development of a truly industrial process

项目UltraWELD将为高度不同的材料开发基于光子的工艺，加入国防/航空航天应用和OLED照明应用的复杂电子光学设备的制造。超快(即皮秒或飞秒脉冲)激光焊接玻璃与金属是目前无法提供满意解决方案的其他粘接技术的替代方案，这些粘接技术不能满足对设备密封的苛刻要求，并且由于粘合剂中挥发性组分的放气而遭受设备退化。我们将为不同材料的连接(微焊)开发新的超快激光工艺，并设计和制造一台能够进行应用开发的灵活的定制激光样机，以在TRL 6级的关键选定真实设备上演示这种激光微焊。该项目将使最终用户尽早采用这项技术，从而使所有五个行业合作伙伴直接受益，通过提高可靠性和使用寿命增强产品竞争力，并降低拥有成本。

Project UltraWELD will develop photonic based processes for highly dissimilar material joining in manufacturing of complex electro optics devices for defence/aerospace applications and OLED lighting. Ultrafast (i.e. pico- or femto-second pulsed) laser welding of glass to metals is proposed as an alternative to other bonding techniques that currently fail to provide a satisfactory solution on demanding requirements for device hermetic sealing and suffer from device degradation due to outgassing of volatile components in adhesives. We will develop new ultrafast laser processes for dissimilar material joining (microwelding) and also design and build a flexible custom laser prototype machine capable of applications development to demonstrate such laser microwelding in key selected real devices at TRL level 6. The project will directly benefit all five industry partners by enabling early adoption of this technology from end users, to enhance product competitiveness by increasing reliability and in-service lifetime and reduce cost of ownership.
