Investigations on laser-welding

IEEE Journal of Quantum Electronics, 1975
A welding method has been developed that makes use of fundamental mode laser pulses. These pulses show single-mode relaxation oscillations with a high peak power first spike causing breakdown of the material surface. The laser emission following the first spike can be adapted to the welding requirements and the material properties.

Surface tension stabilized laser welding (donut laser welding)—A new laser welding technique

Journal of Laser Applications, 2013
A new laser welding process is presented which delivers a porosity free, spatter free weld. The process involves a donut shaped melt with a central hole of the same order of magnitude as the material thickness. The laser illuminates only the leading section of this melt. The hole is kept open by the melt surface tension.

Gases aid laser welding and diode laser welding in particular

PICALO 2004: 1st Pacific International Conference on Laser Materials Processing, Micro, Nano and Ultrafast Fabrication, 2004
The use of lasers has become common in the fields of cutting, welding and surface treatment applications. Various different lasers are used for laser welding. CO2 lasers provide high laser powers of up to 10 kW and more, but require a gantry system to position the laser beam precisely.

Laser welding of magnetic materials

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
