We aim to create the most optimum mix of customised competences, technologies and services to allow our customers to achieve the most cost-effective total solutions.
The laserwelding technology of COVI offers a number of unique technical advantages over traditional soldering, MIG/MAG, TIG and arc welding. With a beam diameter as small as 50 mμ, weldings can be performed in very hard-to-reach spots, what other welding methods do not reach.Welding of complex geometric designs
Our laser technology enables rotational welding, XYZQ plane control and welding with Galvo-head (controlling the beam through specular technology) which means that welding of even very complex geometric designs may be undertaken.Laser welding provides many advantages
When using laser technology, welding is done without the use of welding wire and, thus, the introduction of foreign material is avoided as this may degrade the quality of the product. Laser welding is carried out with the assistance of CAD/CAM-control which ensures great precision and repetitive accuracy. Finally, the thermal impact in the weld zone is minimal, which means that the functionality and look of the product is not damaged.The many possibilities of laser welding
The characteristics and advantages mentioned means that laser technology is unsurpassed in the welding of materials such as:
- Thin-gauge sheeting
- Materials of low melting point (e.g. aluminium)
- Materials of large micro-structural porousness (e.g. sintered metal)
- Materials close to thermosensitive components (e.g. electronics)
All weldable metals may be welded using laser technology. Moreover, the precise control of the molten bath offers good possibilities for welding together different metals.
Welding may be carried out at distances of up to 200 mm, which means that welds that are difficult to access, such as welds in holes or on the inside on tubes, may be carried out.
COVI carries out both manual as well as fully-automated laser welding as well as penetration welding and deep-penetration welding.
