PICALO 2008 Paper #705 (Enhancement of Laser Welding Capabilities by Hybridization or Combination of Different Processes)
Enhancement of Laser Welding Capabilities by Hybridization or Combination of Different Processes
Authors:
Dirk Petring, Fraunhofer ILT; Aachen Germany
Presented at PICALO 2008
The laser welding process is the most flexible fusion welding process industrially available. This is mainly due to the excellent variability of lasers spatial and temporal power distribution down to very small geometries and time scales. The result is high flexibility regarding e.g. weldable materials, achievable penetration depths and possible seam and joint configurations and thereby a big potential for application-specific process optimization. The degree of freedom for optimization is further enhanced and process ...$28.00

Presented at PICALO 2008
Laser cladding based Direct Metal Deposition (DMD) has received significant attention due to its diversified potential for material processing, such as innovative alloying, metallic coating, rapid prototyping and components repairing. Numerical simulation not only helps to understand the complex physical phenomena and the underlying theory involved in this process, it can also be used in the process prediction and system control. The evolution ...$28.00
