Laser welding for precision-demanding tasks.
Laser welding is successfully used when high demands are placed on precision, repeatability, and minimal heat input. The method is particularly relevant for tasks where traditional welding methods either cause too much thermal impact or cannot handle the geometry of the workpiece, including in many types of complex devices.
The technique is typically used for fine mechanical items, microcomponents, tubes, and enclosures, where welding is a functional part of the product's performance. Laser welding is therefore often an obvious choice in several different industries such as medical, electronics, automation, food, aerospace, and other precision components.
In metal, laser welding is used when precise and clean welds are needed on small workpieces, complex geometries, or hard-to-reach welding positions.
Covi offers quality-controlled laser welding
Covi Precision offers various options for laser welding in metal for precision and quality-demanding tasks, acting as a development partner, contract manufacturer, and supplier. Laser welding technology enables technically superior solutions with high precision and minimal thermal impact on the material, which is crucial when joining metallic components.
Covi Precision's expertise in laser welding ensures great versatility and makes it possible to weld complex geometries. The gentle process is particularly suitable for thermally sensitive components and contributes to preserving the mechanical properties of the materials, as well as a uniform and aesthetic final result.
We have equipment for laser welding of various material types, component sizes, and geometries. This allows us to adapt the process to the specific material, ensuring an optimal and reproducible welding solution.
Advantages of laser welding in metal?
Technical benefits
Laser welding in metal offers high precision and great repeatability, ensuring uniform and stable weld quality. The minimal heat affected zone around the weld preserves the material's properties and reduces the risk of deformation, which is crucial for both functionality and aesthetics. Furthermore, laser welding does not use any welding wire, eliminating the risk of contamination from foreign materials.
Complex geometry
COVI's advanced technology enables laser welding of complex geometries, where traditional methods are often limited. Using rotary welding, CNC, and a galvanometer scanner head (control via mirror reflection technology), we can handle even the most complex challenges. Laser welding therefore provides greater flexibility, as it opens up solutions and applications that may otherwise be difficult to achieve with conventional welding methods.
Flexibility in materials
Laser welding can be used for a wide range of metals, including low melting point materials like aluminum, as well as sintered metal with high microstructural porosity. The method allows for working with different metals and, in some cases, combining them effectively within the same process.
Hard-to-reach areas
Laser welding is particularly well-suited for welds in difficult-to-access areas where access and space are limited. Our technology makes it possible to weld in deep areas, for example, inside pipes or in other narrow constructions. This capability for laser welding in challenging positions creates greater freedom in both design and functionality.
Automation and efficiency
Covi Precision offers both manual and CNC-controlled laser welding, providing flexibility for both prototypes and series production while maintaining quality and repeatability. This ensures a stable process where both costs and delivery times can be optimized.
Laser welding at Covi Precision
At Covi Precision, laser welding typically begins with a discussion about the topic, requirements, and desired function. Many solutions involve several technical nuances, which is why we encourage you to contact us early in the process – whether you have a finished drawing or just an idea that needs to be qualified.
When we receive an inquiry, we review material selection, geometry, tolerances, and welding strategy in close cooperation with you. We then assess the optimal process, clamping, and method so that the laser welding is stable, reproducible, and tailored to the specific application.
A significant advantage of Covi Precision is that we have several laser processes at our disposal. In addition to laser welding, we can also laser cut and laser engrave, among other things, which makes it possible to deliver complete solutions and ensure coherence between the processes. We are a specialized company with a short path from dialogue to action, and we see tasks through – from development and startup to series production and large deliveries.
