Laser welding

Laser welding – a welding method with precision Laser welding can be used for various types of joints and joint geometries. By varying optics and laser power, everything from thin foils to thick castings can be welded. Thanks to the laser’s high energy density, neither high melting temperature nor high thermal conductivity of the material creates any problems. Many materials that normally cannot be welded with conventional methods can be laser-welded. This is due to the minimal weld melt and good control of cooling rate. In many cases, no filler material is required. In laser welding both the heat-affected zone around the weld and the total heating of the workpiece are significantly less compared with conventional arc welding. This results in lower deformations and in many cases better strength properties. Thanks to its stability and low profile costly post-processing can be minimised or eliminated.

AM (Additive Manufacturing)

3D printing - in metal and plastic 3D-printing is an additive manufacturing method where material is added layer by layer according to a digital 3D model, making it possible to create complex and customised components without requiring traditional subtractive machining or mould production and casting. Complex and difficult geometries or materials are also not a problem but can be efficiently manufactured with the technology. Lasertech is an experienced full-service provider of 3D-printed articles in both metal and plastic. Since 2014 we have specialised in 3D-printing in metal and are the only subcontractor in Sweden with such long experience in the field. As a complement to metal we also offer 3D-printing in plastic, which means that we can meet a wide variety of customer needs and manufacture a broad spectrum of products across different material areas. We use 3D-printing with laser, SLM (Selective Laser Melting), an effective method for 3D-printing where a layer of metal powder is melted using a laser and then builds the object layer by layer. This process gives us the opportunity to create detailed and strong components with high precision and minimal material waste. The technology is particularly useful for manufacturing complex parts that are difficult or impossible to produce with traditional manufacturing methods.

Laser hardening

Laser Hardening Laser hardening is a method for selectively increasing the hardness and wear resistance of metallic materials. This technique offers high precision and minimal distortion, making it ideal for components that require local hardening without subsequent machining. During laser hardening, the surface is quickly heated by the laser beam to a temperature where the material transforms into austenite. It is then rapidly cooled by the surrounding material, resulting in a hard martensitic structure. This process produces a surface with high hardness and wear resistance while retaining internal toughness. Almost all types of steel gain increased hardness after laser hardening.

Laser marking

Laser Marking Laser marking is a fast technique for industrial marking and traceability marking that works on most materials. Laser marking using the annealing method or the engraving method is useful for, among other things: Traceability with serial numbers Logos on branded goods and giveaways Barcodes/datamatrix for applications that are scanned before use About laser marking Laser marking is a process where a laser beam is used to create permanent marking on various materials by altering their surface, for example by burning, melting or vaporisation. The technique provides high precision and durability.

NDT- Non destructive testing

Non-destructive testing Non-destructive testing (NDT) is an important method for inspecting and ensuring the quality of materials and structures without causing damage. By using methods such as Penetrant Testing (PT) and Magnetic Particle Testing (MT), we can effectively detect surface defects such as cracks, pores, or lack of fusion on or just below the surface of welds, hardened parts, forged stock and machined materials. These methods are particularly useful for products and structures with high safety requirements, where even small defects may have serious consequences. Penetrant Testing (PT) Penetrant Testing (PT) is a method where a coloured or fluorescent liquid is applied to the surface of the object. The liquid penetrates into cracks or pores and becomes visible under UV light or with the help of a contrast colour. PT is particularly effective at finding surface defects on non-porous materials such as metal, plastic and ceramics. It is a fast and cost-effective method for identifying surface defects, making it ideal for inspecting, for example, welds and other surfaces critical to the durability of the product. Magnetic Particle Testing (MT) Magnetic Particle Testing (MT) is used to detect surface defects on ferromagnetic materials such as iron and steel. By creating a magnetic field in the inspected object and applying magnetic particles to the surface, defects such as cracks or pores can be identified. If there is a defect on the surface, the magnetic field will be disturbed, and the magnetic particles will accumulate at the defect, making it easy to see. MT is an effective method for inspecting welds, forged parts and other metal components that are critical to structural integrity.
