| Globo Welding The Globo clamping pressure concept developed by Leister facilitates two and three-dimensional laser welding. Globo welding works along the lines of contour welding. A laser beam is focused at a point on the joining plane via an air bearing, frictionless, freely rotating glass sphere. The glass sphere not only focuses – it also serves as a mechanical clamping tool. While the sphere rolls on the component, it applies continuous pressure at a point on the joining plane. This ensures that the laser beam is only incident at the point at which the contact pressure is also applied. The glass sphere replaces the mechanical clamping device and expands the scope of laser welding for both continuous and three-dimensional applications. In this demonstrational video Globo head attached to a robotic arm is used to weld a taillight assembly. For more information please contact Leister |
| Name: Contour Welding Description: This movie is a simulation showing contour welding, which is the traditional way to laser weld plastics by clamping laser-transparent and laser-absorbent parts against glass and tracing the desired contour from above with laser light focused to a spot. |
Name: Through-Hole Application Description: This movie is a demonstration showing laser soldering, where solder paste is deposited by EFD’s Ultra TT robot next to a through-hole component and reflowed by Leister Novolas system. |
|
| Name: Simultaneous Welding Description: This movie is a simulation showing simulations welding – process similar to contour welding in the way the part is nested in the fixture. On the contrary in simultaneous welding, laser light is optically shaped to a circle, rectangle or other optional geometry, hence eliminating the necessity to travel with the laser around a contour. |
Name: Surface-Mount Application Description: This movie is a demonstration showing laser soldering, where solder paste is deposited by EFD’s Ultra TT robot next to a surface-mount component and reflowed by Leister Novolas system. |
|
| Name: Simultaneous Circle Description: This movie is a demonstration showing Leister Novolas system simultaneously welding two plastic parts with laser light shaped into a circle. |
Name: Integrated Circuit Application Description: This movie is a demonstration showing laser soldering, where a line of solder paste deposition by EFD’s Ultra TT robot across legs of an integrated circuit and reflowed by Leister Novolas system. Thanks to capillary effect, solder paste is sucked away into pads on the circuit board leaving gaps between legs of the IC free of bridging. |

| Name: Mask Welding Description: This movie is a simulation showing mask welding, process developed by Leister to allow precisely and fast weld together complicated patterns. Similarly to contour welding laser-transparent and laser-absorbent parts are clamped against a chrome mask. The laser light, shaped into a line is moved across the part welding together unmasked areas. |

| Name: Globo Welding Description: This movie is a demonstration showing globo welding, process developed by Leister to allow welding in 3D by eliminating the traditional clamp. In globo welding the clamping force is provided by globo ball that rotates freely, floating on an air bearing. The laser light is also delivered through the globo ball. |

| Name: WS Contour Welding Description: This movie is a demonstration showing contour welding, using Novolas WS laser system. |
