Laser welding of magnetic materials [PDF]
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

Solidification type welding process experiments in conditions of microgravity were performed. The role of convection in such phenomena was examined and convective effects in the small volumes obtained in the laser weld zone were observed. Heat transfer within the weld was affected by acceleration level as indicated by the resulting microstructure ...

Vascular tissue fusion by lasers is performed by directing a low energy beam at the apposed edges of the repair. The tissues are approximated with stay sutures or non-reflective instruments and laser energy is passed back-and-forth over the anastomotic site until fusion is achieved.

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
