Abstract Although laser stir welding (LSW) is applied to various metallic systems, it is especially appropriate to laser beam welding (LBW) of aluminum, because liquid aluminum possesses significantly less surface tension and viscosity than most common metal alloys, which results in greater fluidity of the molten pool.

High-power lasers (greater than 5 kW) have been in existence for about two decades. However, their use by industry is extremely limited. Numerous researchers have demonstrated laser welding to a thickness of nearly 1 inch. But almost all laser welding today is for a thickness of 1/8 inch or less.

A series of high-strength alloys has been laser-beam welded in thicknesses of up to 1.27 cm (0.5 in.). These welds in steels, a titanium alloy, and an aluminum alloy have been tested for their mechanical properties, fracture toughnesses, and hardness. The microstructures of these weldments have been determined in the base plate, heat-affected zone, and

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 ...
