The use of lasers, with the addition of materials, has revolutionized the traditional welding techniques of molds, allowing repairs without the need of preheating. This avoids the common collateral damage induced by traditional welding, such as geometric distortions, edge burns and decarburization.
Thanks to the properties of the laser beam, complex areas such as narrow and deep grooves, or internal and external edges, can be welded. The metallurgical quality of the weld meets the highest standards on all steels, copper alloys, and aluminum. The hardness of the welding layers can reach very high values without the need for subsequent heat treatments. Its simple way of operating and perfect visual inspection of the filler material, using a stereomicroscope, make this technology accessible to everyone, without having to rely on highly qualified technicians.
