Gases aid laser welding and diode laser welding in particular
Pacific International Conference on Applications of Lasers and Optics, 2004The 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 and hybrid laser welding of type 316L(N) austenitic stainless steel plates
, 2020The effect of laser, Hybrid Laser-Tungsten inert gas (HLT) and Hybrid Laser-Metal inert gas (HLM) welding processes on the microstructure and mechanical properties of 5.6 mm thick 316L(N) stainless steel weld joints have been studied.

AbstractDeep penetration welding and cutting of metals can be carried out at high speed with relatively low laser power. The efficient coupling of the laser radiation to the metal is due to the formation of a “keyhole.” Over the years, an attempt has been made to transfer the results on metals to plastics.

Spatter, the ejection of melt from a weld pool, is a major problem whenever it occurs in a welding process. The ejection of droplets from the weld metal results in a weld with underfill, undercuts, craters, blowholes, or blowouts—all of which can have a detrimental effect on the mechanical properties of the weld.

SPIE Proceedings, 1997
The role of laser beam parameters and material properties in establishing a stable deep welding process is investigated, experimentally and theoretically. Particular emphasis is placed on the mechanisms involved in the energy coupling. It is shown that high quality welds are achieved by a proper choice of parameters and a sophisticated process ...

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.

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 ...
