Laser welding technology is the most modern way of joining various steels and alloys. Its main advantage is obtaining a very precise geometrically and mechanically strong seam, which has a pleasant appearance and often does not need post-processing.
The working tool is a laser beam which is fed to the borders to be welded. At the focal point (where the pulsed radiation is concentrated in the minimum area) the absorption of the supplied energy by the material and significant local heating occur. The temperature rises, the metal melts and crystallizes after the beam is removed, forming a high quality seam.
It is allowed to weld at any angle of the beam incidence and in any spatial position. Melting is performed to the full thickness of the edge or to some part of it. Depending on welding requirements and parameters a single point, a number of points or a continuous seam is formed.
Special attention is paid to the speed of the beam shift – it directly depends on the input power and the thickness of the metal. Our machines guarantee the welding speed up to 5 mm/sec (in automatic mode). To achieve quality, filler wire, flux or gas shielding of molten metal can be used.
The metal welding laser is notable for its universality: connections are made in mechanical engineering, vehicle and aircraft construction, electronics and instrumentation. It is useful in applying protective coatings on metal (to obtain “endless” ribbon of steel dipped in a zinc bath) and in the creation of computer technology.
It is possible to obtain a welding seam for both the same and different materials, including aluminum and precious metals (silver and other rare-earth metals).
The following laser welding options are technically possible:
Spot: creation of a welded point with not too sharp borders in a fraction of a second.
Seam: the laser beam shifts along the edges and leaves behind an airtight connection.
Combined: protective gas environment and other techniques are used.
Seam with deep penetration: increased power melts the metal to a greater depth and even partially vaporizes it, resulting in a narrow and strong seam.
Each of these varieties is performed by us with complete confidence and with proper training. Parts made by us will stand under load for years to come.
The technology provides a huge number of options for finished products: from blanks with simple shapes to cutouts of complex openings.
Universal and reliable technology for engraving information on metal surfaces: from decorating lighter cases to creating name plates for the aerospace industry.
The feature of the technology is a high-quality connection of materials under any conditions. The method is good in cases where other techniques do not have the proper effectiveness. Also laser radiation for welding has such advantages:
Apart from the requirements for the preparation of the welded edges, the only big disadvantage is probably the decent cost of equipment. Despite this we guarantee a pleasant price result for any technical requirements, no matter how many conditions are not present there. We work all over Europe.
