This paper describes a very successful new method for laser welding of ceramics. Two beam laser welding technology, an additive free procedure, allows one to create joints, e.g. of alumina parts, which have a strength of 85% of the original material. It enables one to join parts of various shapes in only a few minutes without furnaces and in a natural atmosphere. The results achieved as well as the advantages of laser material processing like small welding seams, high flexibility, high productivity and a high degree of automation make this technology ideally suited for industrial application. Applications based on this technology are expected in several branches of technology, for instance for welding tubes or sensor elements, for the protection of electronic components against high temperatures, abrasion and/ or chemical attack.
