21. ExamplesLaser Lasers in material processing HPDL*= high power diode laser properties of HPDL (diode laser) • high efficiency •compact • low-maintenance/ high life time • low beam intensity
39. ExamplesDesign Considerations Weldability of Material Material A and B are based on the same material (PC with PC / ABS with ABS....) Material A and B are made of different but compatible materials (PMMA with ABS, PC with PBT.............) Optical properties of the Material is Suitable for Laser Transmission Welding? Material A - transparent to laser radiation (e.g. clear material) Material B - absorbs the laser radiation (e.g. Contains 1% Carbon Black) Dimensions and shape of part and the welding seam are designed laser compatible? Accessibility for laser, planarity, possibility to apply pressure?
100. ExamplesGlobo welding Requirement:welding of 3D components, large areas or continuous-feed applications flexible like contour welding Method: spot optic combined with a dynamic clamping device Globo welding Quelle: ILT
103. ExamplesRadial welding Requirement: welding of rotationally symmetrical components without relative motion Method: special optics and conical mirror Radial welding Photo: Leister, by courtesy of comp. Rasmussen, Maintal (Germany)
148. Examples Demo (Fair: K 2004) Requirement:short-time process no relative motion mass production Method:laser beam formed and guided by optical elements Simultaneous welding Material: PC nature / PC black
