Laser beam welding is a high-power density process used to join multiple metal workpieces through the heat produced by a laser. The key feature of this laser beam is its ability to sublimate the metal of the contact area on the workpieces and melt the surrounding material.
The distinctive features of this welding technique are its speed, entailing shorter thermal cycles and thus ensuring an excellent depth, and the ability to modify the structure of the heated material in a small area, which also allows to reduce workpiece deformations due to the process.
This technology requires that both the workpiece and the welding environment be thoroughly cleaned.
Six-axis laser beam welding centre – for the processing of two-dimensional and tridimensional workpieces. Welding technique without filling material and with a penetration depth through steel alloys up to 7 mm, and 5 mm through aluminium alloys; it allows welding with filling material through the use of an unwinder for coils of wire. These are the key strengths of the laser beam welding: the weld bead’s depth/width ratio, the reduced heat input and ZTA. Therefore it is possible to obtain a deep welding penetration and a reduced weld bead width.
Pulsed laser beam welding machine. It can weld all metal alloys, as well as aluminium and copper. Reduced heat input; thus workpiece deformation is almost non existent. Peak power output of 6,000w. Suitable for the welding of very small workpieces. Equipped with eyepiece visor for the operator, this allows for maximum precision in positioning the welding area. It allows welding by using filler material with a maximum diameter of 1 mm.
