New ink dispensers help laser Weld Clear parts. (Keeping Up With Auxiliaries).Laser welding Laser welding Welding with a laser beam. The primary apparatus is the continuous-wave, convectively cooled CO2 laser with either oscillator/amplifier (gaussian output beam) or unstable resonator (hollows output beam) optics. of translucent translucent slightly penetrable by light rays. parts is now feasible, thanks to a new laser-absorbent ink and specialized ink-dispensing systems from two suppliers working in partnership with the ink developer. ClearWeld, a process developed by Gentex Corp. in Carbondale, Pa., requires precise deposition of inks formulated to absorb near-infrared (NIR NIR Near Infrared NIR National Inventory Report NIR National Identity Register (UK) NIR Near-Infrared Reflectance NIR Non-Ionizing Radiation NIR Net International Reserves NIR National Internet Registry NIR Northern Ireland Railways ) laser light. Previously, laser welding required one part to be infrared-absorbing, limiting it to only black or dark-colored parts. With ClearWeld, the laser passes through the clear plastic, but stops at the joint, where it is absorbed by the ink and generates enough heat to create a weld. The ink-dispensing equipment suppliers are Nordson Corp. of Duluth, Ga., and Xennia of Royston, Hertfordshire Coordinates: Royston is a town in the east of England in Hertfordshire, England. It is situated just west of the Greenwich Meridian, which passes through the point where the bypass meets the original A505 alignment. , U.K. They have developed, respectively, a liquid spraying system and an ink-jet printer for accurate application of Gentex's inks. "They open the way for implementing our technology," declares LP Frieder III, marketing manager at Gentex. Nordson's Product Assembly Group offers a ClearWeld package consisting of a spray apparatus, tips, and syringes. Nordson also supplies robots and 3D motion-control tables required for precise product placement, ink dispensing, and laser manipulation in low- to medium-volume operations. For high-volume welding welding, process for joining separate pieces of metal in a continuous metallic bond. Cold-pressure welding is accomplished by the application of high pressure at room temperature; forge welding (forging) is done by means of hammering, with the addition of heat. , Nordson offers customized tabletop work cells. Meanwhile, Xennia's XPS (1) See XML Paper Specification.

An integrated IR lamp ensures efficient ink drying after deposition. Nordson: (800) 683-2314, www.nordson.com / productassembly; Xennia: +44 1763 24 6600, www.Xennia.com |
