Laser Welder, BTI Fiber Weld 4

The Fiber Weld V4.0 is a personal fiber coupled laser welding system. The active material is a YAG crystal with diffusion of active atoms. The pumping system is of the optic type, by means of a lamp. It consists of a pulsed, Nd:YAG laser. The entire system was designed and produced with a high degree of modularity so as to provide an ergonomic product featuring simplified maintenance. It is composed of a resonator and an electric cabinet containing the electrical power components and the cooling system, which are connected and form a single body of limited dimensions. The Fiber Weld V4.0 is connected by means of an optic fiber to the work console, which is called the WWB (Welding Wired Box), inside of which is located the Joystick for the adjustment of parameters. The FME (evolved, motorized focusing device), which focuses the laser beam at the required position, is mounted on the top of the Glove Box. The WWB is fitted with all of the safety devices needed to impede emission of potentially dangerous laser light. The welding parameter control panel with its graphic display is attached to the cabinet with magnets. It can be detached and repositioned as preferred by the operator, thereby offering a feature which enhances the ergonomics of the entire system.
