By Geoff Giordano If additive manufacturing is becoming the next big thing as some experts and companies believe, the Laser Institute of America’s fifth-annual Laser Additive Manufacturing (LAM®) Workshop helped pave the way by providing more information on the road map leading to an AM revolution. Situated in its largest venue yet, LAM 2013 featured […]
LIA Aids NPI in Revolutionizing US Manufacturing with Laser Technology
By Geoff Giordano With the US government running a full-court press to foster manufacturing innovation, the Laser Institute of America made the case for laser-based advanced manufacturing processes during a special presentation in the nation’s capital. LIA representatives advocating laser-driven manufacturing joined four other subcommittees discussing the growing usage of lasers in health, defense, energy […]
Electromagnetic Control of the Weld Pool Dynamics in Partial Penetration Laser Beam Welding of Aluminium Alloys
By Vjaceslav Avilov, André Schneider, Marco Lammers, Andrey Gumenyuk, Michael Rethmeier A well-known problem of partial penetration laser beam welding is keyhole-tip instability representing the main source of porosity – gas bubbles leave the keyhole near its tip. The second important problem of keyhole mode laser welding is very intensive thermocapillary (Marangoni) convection in the upper […]
Novel Fusion Welding Technology of Si/Glass Using Ultrashort Laser Pulses with High Pulse Repetition Rates
By I. Miyamoto, Y. Okamoto, A. Hansen, T. Amberla, J. Vihinen, J. Kangastupa Silicon/glass is one of the most widely used material combinations for sensing and actuating microsystems and micro electronic technologies. Anodic bonding has been most widely used for Si/glass bonding since its invention in 1969, because of its excellent mechanical properties and process […]
The Difference Between Fiber Lasers and Fiber Delivered Lasers
By Tony Hoult Nobody would disagree that real change is occurring in the laser industry. In the broadest context, what is happening is a shift from the conventional technique of assembling lasers using free space optical components to a technique based on splicing together fiber based components. It is now very widely accepted that this […]
