Effect of laser welding parameters on the heat input and weld-bead profile [PDF]
Journal of Materials Processing Technology, 2005 Laser butt-welding of medium carbon steel was investigated using CW 1.5 kW CO2 laser. The effect of laser power (1.2 - 1.43 kW), welding speed (30 - 70 cm/min) and focal point position (-2.5 - 0 mm) on the heat input and the weld-bead geometry (i.e ...

Naval Engineers Journal, 1981
ABSTRACTTechnological improvements in welding have proceeded at a slow pace usually brought about by incremental advances in techniques or materials. An opportunity is now being afforded the Navy to increase its welding technology by giant steps by utilizing the emerging technology of laser welding.

Diode Laser Welding of Polyethylene
Polymer-Plastics Technology and Engineering, 2008A high-power diode laser (HPDL) was used to weld high-density polyethylene (HDPE) sheets. Laser-welded joints were fabricated with different values of laser power and scan speed. Hot-tool welding was also employed to fabricate joints to make a comparison between this consolidated technology and HPDL welding.

A neodymium glass laser was used to produce weld joints between test pieces of four different casting gold alloys. The mechanical properties of the welds were determined and their microstructures were evaluated. The results of this study indicate that laser welding of dental casting gold alloys is metallurgically feasible.

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.

Laser welding of titanium in dentistry
Acta Odontologica Scandinavica, 1988Unalloyed titanium of the quality used for osseointegrated implants by the method of Brånemark is also sometimes used for the metallic part of the prosthetic superstructure placed on the fixtures and for crowns and bridges of conventional type. Forty bars of titanium, 8 of ASTM B 348 grade-1 quality and 32 of ASTM B 348 grade-2 quality, were laser ...

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, 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 magnetic materials
Conference on Lasers and Electro-Optics-Europe, 1998Industrial 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

Weld pool oscillations in laser welding
ICALEO '95: Proceedings of the Laser Materials Processing Conference, 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.
