Optoacoustic Monitoring of Laser Beam Welding

Proceedings of European Meeting on Lasers and Electro-Optics CLEOE-96, 1996
To fully exploit the productivity and flexibility of laser beam welding unit, a reliable monitoring is necessary. Different physical phenomena like light emission and temperature are usually observed and evaluated for that purpose [1]. The aim of this paper is to extend the observed phenomenon to sound which is produced during welding and spread into ...

Laser Beam Welding and Design

2021
Laser welding is a fusion welding process and uses a laser beam of a determined spot size to cause melting of the workpieces and the filler material to form the weld. Laser welding, when it originated had taken over as an advantageous technique over the traditional arc welding methods in high-volume manufacturing industries.

Laser beam welding with a hybrid laser system

ICALEO 2000: Proceedings of the Laser Materials Processing Conference, 2000
Diode lasers are a new high-power beam source for material processing. In comparison to conventional beam sources like CO2 – or Nd:YAG – lasers they have the advantages of small size, low maintenance costs and considerably higher efficiency. Currently one advantage of Nd:YAG – lasers is better beam quality allowing higher focus intensity.

Development of the laser stir welding process for aluminum laser beam welding

ICALEO 2005: 24th International Congress on Laser Materials Processing and Laser Microfabrication, 2005
Laser stir welding involves the manipulation of the laser beam to provide hydrodynamic stirring and subsequent healing of the keyhole. Since aluminum alloys tend to be especially sensitive to keyhole stability, the process has been conceived for laser beam welding of these alloys.

Temper-Bead Weld by Underwater Laser Beam Welding

Volume 1: Plant Operations, Maintenance, Engineering, Modifications and Life Cycle; Component Reliability and Materials Issues; Next Generation Systems, 2009
In repair welding for nuclear reactor vessel, low alloy steels are affected by heat input during welding process. The conventional repair welding for wall steel constructions requires post weld heat treatment (PWHT) to achieve the desired microstructure properties.
