Weld pool oscillations in laser welding
International Congress on Applications of Lasers & Electro-Optics, 1995The weld pool oscillations in laser spot welding were investigated experimentally using high speed schlieren photography and probe laser beam reflection technique. Millisecond, 3 kW power pulses from a Rofin-Sinar RS3000 CO2 laser were used for spot welding of SS304 stainless steel samples.

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 Welding of Vesicovaginal Fistula
International Urogynecology Journal and Pelvic Floor Dysfunction, 2001The management of vesicovaginal fistula remains a source of debate, despite extensive literature on the subject. It is difficult to prove the superiority of one surgical technique over another by randomized trials, given the variabilities of fistula etiology, the location and clinician expertise.

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.

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 ...

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.
