Abstract

UN PROCESO Y UN APARATO DE SUELDA POR LASER EN EL QUE UNA PLURALIDAD DE RAYOS LASER (32A, 32B) SON ENFOCADOS POR UN DISPOSITIVO DE ENFOQUE (30) EN LAS SUPERFICIES DE LAS PIEZAS DE TRABAJO (14A, 14B) DE MANERA QUE LOS PUNTOS DE LOS RAYOS LASER SON COLOCADAS CERCA DE UNA INTERFAZ (16) DE LA PIEZA DE TRABAJO SEGUN SE MIRA EN UNA DIRECCION PERPENDICULAR A UNA DIRECCION DE LA EXTENSION DE LA INTERFAZ, Y LOS PUNTOS DE LOS RAYOS Y LAS PIEZAS DE TRABAJO SON ALIMENTADAS EN RELACION MUTUA POR UN DISPOSITIVO DE ALIMENTACION (43, 54, 56) EN LA DIRECCION DE LA EXTENSION DE LA INTERFAZ, MIENTRAS QUE LOS PUNTOS DE LOS RAYOS SON OSCILADOS AL MISMO TIEMPO POR UN DISPOSITIVO DE OSCILACION (36, 40) A UNA FRECUENCIA PREDETERMINADA EN RELACION CON LAS PIEZAS DE TRABAJO EN UNA DIRECCION QUE CRUZA LA DIRECCION DE LA EXTENSION DE LA INTERFAZ DE TAL FORMA QUE LOS PUNTOS DE LOS RAYOS SE DESPLAZAN POR LA INTERFAZ.
