  • Two Laser Weld Seams at One Time
    . Eventually a profile form having two parallel welded seams proved to be stable enough. Commonly used welding methods, such as High Frequency, Spot or Resistance-Seam Welding were quickly excluded due to cross-section or welding speed. But could we avoid any surface imperfection after the profile

Titanium (Ti). speeds, higher speeds produced almost full. penetration. High quality welds with smooth top. beads
  • Battery Welding Solutions Using Resistance & Laser Technologies (.pdf)
    In the battery industry, the use of resistance welding for electrical connectivity and battery pack manufacture dates back many decades. The weld controls that provided the foundation for this market were Capacitive Discharge (CD) and AC welders. This technology remained largely unchanged for many

    melting point (below the melting point of the base metals) is added to the joint and reflowed in place. Among such materials are tin-lead, gold-tin, and copper-silver alloys. Common reflow methods include rapid infrared heating using quartz lamps or parallel-resistance seam welding set up to reflow
  • Laser Assembly of Microfluidic Devices (.pdf)
    parts with its main related process characteristics and its potential for low-cost and high volume manufacturing. The system consists of a of diode laser with a mask and automated alignment function to generate micro welding seams with freely definable geometry. A fully automated mask alignment system
  • Medical Device Link .
    EQUILASERS INC. (Sunnyvale, CA) has introduced a self-contained laser station for spot welding, seam welding, wire welding, and reflow soldering. The system sits on a bench with a footprint of approximately 3 x 5 ft. At the workstation's core is the Equilaser EDW-15, a 15-W Nd:YAG laser welder
  • Medical Device Link .
    A fully modular Class I laser workstation has been designed for precision seam, lead, and spot welding in medical device and other applications. According to Mark Plasse, vice president of manufacturing at Litron Inc. (Springfield, MA), the BT-40W workstation is unique because it is "self-contained
