Minimizing dilution by automatic adjustment of laser power
| Our in-house lasercladding department continuously focuses on innovation and improving techniques for laser surface modification. Stork Gears & Services is participating in an application project together with NIMR and the University of Twente. The application project is part of the Surface and Interface Engineering research cluster. This cluster deals with the interdisciplinary fields of surface engineering, from materials science to computational mechanics. Lasercladding is an innovative laser technique for surface treatments utilizing a laser beam as the heat source. This weld surface technology reduces distortion and dilution due to low heat-input and a small heat-affected zone. Laser cladding can be used to effectively apply wear and corrosion resistant layers on surfaces. An ongoing challenge of lasercladding is 100% metallic adhesion with a minimum of dilution. The project focuses on minimizing dilution by meltpool detection and realtime control of the laser power and heat input. Optimizing the laser cladding parameters with a cmos industrial camera and online monitoring are one of the main issues of this project. About NIMR NIMR* is the world-class institute for applied metal research and runs an ambitious research programme to strengthen the capacity for innovation and the competitive strength of the Dutch metal industry. All in close cooperation with her industrial partners (e.g. Stork, Corus, DAF) and research institutes (e.g. University of Twente). Stork is member of the Executive Board of NIMR. The research was carried out in the framework of the Strategic Research Program of the NIMR. * NIMR stands for Netherlands Institute for Metals Research. For more details, please visit www.nimr.nl |
