Welding

Laser welding
This is a welding process in which a focussed laser beam is used to fuse materials. This technology enables very high precision and efficiency. In laser welding, a laser beam is generated and focussed on a small area of the workpiece. The intense energy of the laser heats the material quickly, it melts and forms a weld seam. The laser beam can be customised.
Advantages: High precision – Speed – Minimal distortion – Versatility – Automation capability
Challenge: Not all materials are equally suitable for this technique

Automated welding cells with welding robots
Automated welding cells are specialised workstations equipped with welding robots. These robots carry out welding work autonomously, based on pre-programmed instructions and sensor feedback. The following welding processes can be used: MIG/MAG welding.
Advantages: increased productivity – consistent quality – cost efficiency – flexibility

Spot welding
Spot welding is a welding process widely used in industry. It is a form of resistance welding in which several metal sheets are joined together at specific points. This is achieved by applying pressure and passing an electric current through the workpieces. The electrical resistance generates heat, which melts the metal at the contact points and thus creates a solid connection.
Advantages: Speed – efficiency – cost savings – strength and reliability – automation capability
Challenges:
• Material thicknesses: Different material combinations and material thicknesses can influence the result.
• Accessibility: Welding can be difficult in places that are difficult to access. Robots and special electrode moulds can help here .
• Influence of heat: The influence of heat can affect the material properties.

Stud welding
Stud welding is a welding technique that enables fast, reliable attachment of studs, pins and other fastening elements to metal workpieces. The process can be carried out both manually and automatically. The most commonly used materials are steel, stainless steel and aluminium.
Advantages: Speed – strong connections – flexibility – minimal pre- and post-processing – automatability
Challenges: Material differences – Surface preparation – Accessibility

WIG/MIG/MAG welding processesWIG welding
(=Wolfran inert gas welding)
It is also known as TIG welding (Tungsten Inert Gas). A non-melting tungsten electrode and an inert shielding gas are used to protect the weld seam from contamination/oxidation. The process enables maximum precision and quality.

MIG welding (=metal inert gas welding)
MIG welding is also known as metal inert gas welding. The application uses a continuously fed wire as an electrode and an inert gas to cover the weld seam. It enables easy handling with high productivity and can be used for a variety of materials, especially aluminium and stainless steel.

MAG welding (= metal active gas welding)
MAG welding is also known as metal active gas welding and is similar to MIG welding. It uses active gases and gas mixtures to protect and influence the welding area. It is particularly suitable as a cost-effective solution for thicker materials and large volumes.
