Several types of lasers are currently used for materials processing (cutting, welding, and drilling) in the aerospace industry. Te most frequently used lasers are CO2
and Nd:YAG lasers for a wide range of (gas
lasers) for cutting and welding applications while high peak power Nd:YAG (solid state lasers) are used primarily for drilling applications. Te last decade has seen the rise of high-power diode-pumped fiber lasers. Tese new lasers have been demon- strated as a serious alternative to both CO2
materials processing applications in the aerospace industry. Te advantages of high-power fiber laser for drilling cooling holes in aerospace
engine components is well documented. Fiber laser provides distinct advantages in many drilling applications in speed, quality and cost over CO2
and Nd:YAG laser
based processes. Te latest challenge is to apply fiber laser welding to aerospace components and achieve similar advantages.
Fiber Laser Welding vs. Arc and Electron Beam Welding Most aero-engine components are made of titanium, nickel, and cobalt alloys.
