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 beam welding has been used for joining zinc coated steel in the automotive industry. However, overlap laser welding of these steels is considered to be difficult because of the low boiling temperature of the zinc compared with the melting temperature of the steel. To date welding is normally undertaken when a gap is present between the plates, introduced prior to welding, or when welding with a modified laser beam configu...$28.00

Presented at PICALO 2008
Practically, the melted bath movements induced during deep penetration laser welding can be controlled by external effects that can lead to make the flow more uniform. A technique consisting in directing an inert gas jet towards the keyhole aperture under a given angle and height of the gas delivering nozzle is used, and a laminar flow is observed. Consequently, the formation of porosities can be thus reduced, and the ob...$28.00

The hydrodynamics evolution of the melt pool during laser Yag welding of stainless steel has been experimentally studied by using a high-speed video camera that allowed us to analyze the main characteristic parts of such melt pools. Depending on operating conditions, very different and complex hydrodynamic behaviors can be observed when the welding speed varies from typically a ...$28.00
