  • Combination of Sensing Techniques Checks Laser Weld Quality
    COLUMBUS, Ohio -- A trio of sensing techniques combine to form a single, reliable system that can inspect the quality of high-power laser welding, according to a study at Ohio State University. While each individual technique inspects welds with only modest accuracy, combining the three can detect
  • Two Laser Weld Seams at One Time
    was powder-coated? This question gave us the idea of laser welding. "Far too expensive!", was the first reaction, as two lasers would actually be necessary for both welding seams. But we did not throw in our project engineer's towel so quickly. The final concept convinced our demanding customer
  • Laser Spot Welding of Copper to Stainless Steel
    Copper is typically the most challenging material to laser weld, welding it to a less expensive dissimilar material such as steel is doubly challenging. This work was done to demonstrate the capability of the fiber laser in this novel material combination. Due to the challenges of welding copper
  • Laser Staking Securely Joins Plastic Parts for Printed-Circuit Boards
    and automation. Picking plastics to laser weld , " Machine Design, Sept. 18, 2003 Manufacturers of electronic components with printed-circuit boards (PCBs) have a new method for mounting PCBs to their respective thermoplastic housings or substrates: laser staking. The technology uses the same principles
  • Laser Welding of Plastics (.pdf)
    Plastic welding using a laser source has become an alternative to conventional plastics joining technologies, such as gluing, ultrasonic, vibration or element heating technology by offering flexible seam contouring, minimal heat input and consistent weld quality. The laser source can be either Nd
  • Laser Integrated Robotics (.pdf)
    In recent years laser welding has advanced into many different industries, from automotive to electronics. With lasers, it is possible to weld a high speeds with great efficiency. Once unthinkable applications and processes are now being developed into working systems.
  • Laser Welding of Brachytherapy Seeds
    . The above metallographs show successfully welded Titanium brachytherapy seeds. Figure 1 shows Medium power welding at 35 W. X-axis travel 1 mm in 3s, laser duration 3s. This was seen to be a highly reproducible process with the spherical external surface being quick to produce. The convex internal surface
  • Laser Spot Welding of Copper
    application for lasers especially at the near infra red wavelength. A series of small spot welds were made using 170W CW and a weld time of 0.1s to weld two pieces of 0.1 mm thick copper together. The concentric rings visible on these samples confirm that the high power density of the fiber laser
