Nd:YAG LASERs are commonly defined as "solid-state LASERs". The active LASER medium is a crystallite of Yttrium and Aluminum, doped with Neodymium, which after being stimulated by a strobe light emits a coherent, monochromatic and concentrated light wave, in a rectilinear and one-way beam: the LASER beam.
Nd:YAG crystal LASERS emit infrared light with a wavelength of 1064nm either in continuous (CW) or pulsed (CCW) modes; the latter is normally used for welding, exploiting the most of its natural capacity to supply large quantities of energy (up to 20kw) in very short lapses timed in milliseconds.
The LASER-welding process uses this high density energy, supplied in short periods of time, to rapidly, almost instantaneously, brings the metal to its melting point, reducing thermal stress to the minimum and creating smaller, cleaner, deeper, and better quality welding spots when compared to those obtained by using traditional welding techniques.
The main advantages of welding by LASER, in addition to neatness and precision, are:
OROTIG is a world leader in the production of solid-state LASER-welding equipment, which emit a pulsed LASER-light. The advantages of this type of welding are best expressed when applied to metals such as gold, silver, platinum, palladium, titanium, stainless–steel alloys, , cobalt-chromium- and nickel-chromium based alloys, cast-iron, and many other pure metals and alloys.
Our range of LASER-welding equipment includes:
Thanks to versatility and the broad selection of workable metals/alloys, OROTIG’s LASER-welding machines are chosen every day by high level professionals in a broad range of industrial sectors, for the production of jewels, metal dental restorations, orthodontics, eye-glass frames, thermocouples, cardiac stents, and other uses.
