• Micro-Joining With Electron Beam Energy (.pdf)
  extensive calibration. Electron beam, comparable to laser, can utilize pulsed energy. cycles. The pulsing of high energy electron beam has been extensively. studied for the advancement of joining materials. High repetition rates. of up to 1000 Hz have been found to control the undesirable thermal. shock...

  , process that has generated interest is electron. beam welding. This article looks at the chronology of. tool steel cladding from arc welding through electron. beam welding to the introduction of indus-. trial laser processes. Cladding and welding restora-. tion of tool steel surfaces. began with GTAW...
• Better Hearing Thanks to Laser Welding (.pdf)
  is the new cerumen. welding ­ is used for joining the diaphragm to the carrier. protector «SmartGuard». This uses a 15 µm thick polymer. ring. This involves connecting a joining partner that is trans-. diaphragm to protect the sound outlet from cerumen and. parent to laser radiation with an absorbing...
• Combining 2-D and 3-D Laser Applications
  part geometry, lot size, scrap rate, machine acceleration, material handling, beam mode quality, and gas delivery. Laser know-how has matured to the point where even the most knowledgeable operator can improve the fabricating operation only so much. www.mitsubishi-world.com - Combining 2-D and 3-D...
• Laser Staking Securely Joins Plastic Parts for Printed-Circuit Boards
  the surface. The joining partner, a rivet head made from a laser-transparent material, is placed in contact and under pressure at the end of the stake. A single-emitter laser diode emits a 980-nm wavelength beam, the same type used for LTTW. The laser usually uses 20 to 50 W; the most common power...
• Laser sensors to guide VW Passat in next Darpa Challenge
  and its reflection being received determines the distance to the object. A rotating mirror lets the laser range finder operate as a scanner, with the mirror deflecting each outgoing beam. This lets the system build a profile of the environment within the laser scanner's range. The car, fielded by a group...
• Laser Use Heats Up
  into a multi-axis machine that allows for at least 5-axis numerically controlled work. The beam exiting the laser is poorly formed for heat treating because it has hot spots and weak areas. It can, however, be shaped into almost any desired pattern using a number of different devices...
• Seeing In Nanometers: Laser And Gratings Make Tiny Motions Visible To Human Eye
  grating layer is hidden below the first. The area of the grating itself is 10 X 10 mm. The scale bar at bottom represents 10 mm. A researcher studies tiny motions formerly invisible to the human eye, using a laser beam interacting with a diffraction grating fabricated at Sandia's Microelectronic...
• Laser Drilling is a Key Process for Refurbishing Turbine-Engine Components
  machining capabilities and highly skilled operators. His company uses a Laserdyne 790 BeamDirector from Laserdyne Systems, Champlin, Minn. Using the same programming coordinates shared by new parts, operators reestablish hole locations, align the laser beam, and then confirm hole position...
• New "window" of opportunity for e-beam welding
  at high speed, jobs routinely done by YAG and CO2 lasers. E-beam processes are 50 to 90% more energy efficient than laser welding and drilling. Side-view cross section of 0.090-in.-deep weld in 316 stainless steel. Weld speed is 6 ipm. Weld width is 0.120 in. A 100% penetration weld through 0.125-in...
