ABSTRACT:
A method is disclosed for the welding of two or more glassy metallic ribbons into a monolithic or composite glassy metallic body. The method includes the step of drawing the ribbons in converging fashion through a nip between two high speed rotating rollers. A heat source is generated with a series of laser beams focused at spaced intervals along the nip between the converging and contacting ribbon surfaces prior to compressing the ribbons together. The welded body is internally cooled at a rate sufficient to retain the ribbons and the weld zone therebetween in a glassy metallic state following welding. The parameters of temperature, ribbon speed, exposure time, laser beam power and ribbon thickness for the process are disclosed. In the preferred embodiment, full width welding in a narrow rectangular area adjacent the line of convergence is generated to provide a monolithic body; whereas, in an alternative embodiment strip/spot welding is provided between the ribbons.
