The polymer coated thin steel sheet is used for materials for electronics and building applications. At least two steel sheets are joined by tight rolling at their edge for the materials processing. The edge of the steel sheet is needed to be wrapped inside the joint roll and be sufficiently sealed off against th...$28.00

Presented at ICALEO 2007
Laser beam welding of thermoplastic polymers offers innovative solutions to overcome limitations of conventional joining technologies. These benefits are used in more and more industrial applications due to the accuracy and flexibility of the process and the quality of the weld seams. To meet industrial requirements specific welding procedures (contour, quasi-simultaneous or simultaneous) or adapted materials (color) have already been developed. In parallel new sectors o...$28.00

Computation of Temperature Fields for Laser Transmission Welding of Plastics
Authors:
Thomas Frick, Bavarian Laser Centre; Erlangen Germany
Presented at ICALEO 2007
Laser transmission welding of plastics is a joining technique which permits the welding of plastic parts with low thermal and mechanical stresses. In order to compute the temperature fields during the welding process a simulation model of the process is established. Especially the optical and thermal properties of the welded materials are necessary as input parameters in order to model the process properly. While the thermal properties of polymers are well-investigated, there is little knowledge about the optical properties of plast...$28.00

Adaptive Metal Deposition and Data Management for Automated Overhaul of Complex Turbine Components
Authors:
Claus Bremer, BCT GmbH; USA
Presented at ICALEO 2007
The automated overhaul of turbine components consist of a chain of different processes as inspection, material addition and re-shaping. The direct metal deposition methods have been improved by employing adaptive machining technology. The adaptation algorithms make use of the geometrical information provided by optical scanning systems or in-process measuring equipment and compensate for the part-to-part variation of the turbine components to be overhauled. With this approach, the metal deposition of the individually worn and deformed...$28.00

Presented at ICALEO 2007
Laser net shape manufacturing (LNSM) is a laser cladding based technology which can prototype and repair three-dimensional components with complex geometries. Manufacturing macro-parts with small feature size usually requires a small laser beam and slow deposition rate, which sacrifices the manufacturing speed when one contemplates fabricating entire parts. Depositing materials adaptively according to the geometric...$28.00
