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

UltraWELD项目将开发基于光子的工艺，用于制造用于国防/航空航天应用和OLED照明的复杂电光器件。玻璃与金属的超快（即皮科或飞秒脉冲）激光焊接被提出作为其它结合技术的替代方案，所述其它结合技术目前不能提供满足器件气密密封的苛刻要求的满意解决方案，并且由于粘合剂中挥发性组分的脱气而遭受器件劣化。我们将开发用于异种材料连接（微焊接）的新型超快激光工艺，并设计和制造能够进行应用开发的灵活定制激光原型机，以在TRL 6级的关键选定真实的设备中演示此类激光微焊接。该项目将使所有五个行业合作伙伴直接受益，使最终用户能够尽早采用这项技术，通过提高可靠性和使用寿命来提高产品竞争力，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.
