Glass and Ceramics, 2018
Laser glass-welding technologies are reviewed. Welding technologies using continuous wave CO2-laser radiation in the surface-heating regime and in a deep melting regime are presented. A technology of microwelding of glass by lasers with ultra-short pulses and high pulse repetition frequency is examined.

International Congress on Applications of Lasers & Electro-Optics, 1988
The welding of aluminium and its alloys with CO2-lasers is not yet state of the art. The reasons for this are: – the high reflectivity – the thermal conductivity – the low ionisation energy – chemical reactions of the alloyed elements These properties are the reasons for a stronger dependence of the welding results from the process parameters in the ...

Laser welding of magnetic materials [PDF]
Conference on Lasers and Electro-Optics-Europe, 1998 Industrial sectors with interest in welding magnetic materials include the aerospace, electrical and defence industries [1]. The effects of CO2 laser welding and high temperatures (i.e. above the Curie temperature) on the magnetism of ferromagnetic materials were investigated. A 1.2 kW MFKP CO2 laser was used to weld the magnetic material at a constant

International Congress on Applications of Lasers & Electro-Optics, 1989
Solidification type welding process experiments in conditions of microgravity were performed. The role of convection in such phenomena was examined and convective effects in the small volumes obtained in the laser weld zone were observed. Heat transfer within the weld was affected by acceleration level as indicated by the resulting microstructure ...

SPIE Proceedings, 1988
Vascular tissue fusion by lasers is performed by directing a low energy beam at the apposed edges of the repair. The tissues are approximated with stay sutures or non-reflective instruments and laser energy is passed back-and-forth over the anastomotic site until fusion is achieved.
