Laser heads series VF belong to the new class of heads for fiber lasers, namely systems with adjustable relative focal length. This is the basis of technological systems designed by the specialists of STC ELECTRORESURS.
The technological tests accomplished have demonstrated full compatibility of the head with laser design, possibility of performing a wide spectrum of operations and work safety.
Fibre lasers with vario-heads VF001 М can be used for the following operations:
laser metal cutting — with use of different materials and metal thicknesses
perforation — manufacture of meshes and filter elements with transparency up to 30%
welding — high-performance butt-seam welding without application of filler materials, including welding of structures such as «tube-tube plate»
hardening of surfaces — local treatment of parts to increase metal strength
build-up welding — modification of surfaces with use of metal materials requiring high accuracy and locality
cleaning — noncontact environmentally friendly and high-performance method
marking and engraving.
All these processes are highly effective and efficient as compared with traditional technological methods of surface processing.
