The laser welding is a welding process in which the Supply of energy via a laser he follows. The main area of application is in Welding of components. These are in particular components that have a high welding speed, slim weld seam shape and low thermal distortion be joined. Often used in laser welding without a filler material worked. Another common term for laser welding is what is known as Laser beam welding.

ARNOLD MACHINE FACTORY IN RAVENSBURG
As a medium-sized family company, we can look back on around 100 years of company history. Anton Arnold laid the foundation stone in 1919 with a special welding shop for cast and aluminum.
Today we produce and develop complex laser systems including the necessary automation components and device technology.
Initially, the focus was on laser welding, but now more and more complete solutions are in demand. This means that additional processes such as heating, pressing and quality assurance in addition to welding
need to be delivered. The automatic material flow through robot technology and a wide variety of conveyor technology and storage systems complete our scope of services.
Questions and answers about laser welding
How does laser welding work?
The energy is supplied via a laser. It is mainly used for welding components that have to be joined at high welding speeds, with narrow and slender weld seams and with little thermal distortion. The process, which is often called laser welding, is usually carried out without a filler material.
What are the advantages of laser welding?
High precision, high repeat accuracy, low heat input into the component, low thermal distortion of the components, low operating costs, high efficiency, welding complex seam geometries.
What can you do with laser welding? (Application areas)
Connection of two components. Materials: metal, plastic, glass, carbon, etc.
Why Arnold as a partner in laser welding?
We produce laser systems for different applications and customer requirements. Core processes are all in-house. Internal process development and production in our laser center. Continuous activity in research and development projects. Reliable, productive machines with high availability.
What temperature is generated during laser welding?
Plastic: 150 to 350 ° C
Aluminum: 600 ° C
Glass: 600 to 800 ° C
Copper: 1085 ° C
Steel: 1400 ° C
What is the process like during laser welding?
With laser welding, light is bundled onto a 0,2 to 2 mm small spot with the help of focusing optics. The energy input at the focal point is very high, which causes the material surface to melt quickly. Depending on the welding requirements, the joint can be made with or without different welding consumables (wire). At the same time, the resulting weld seams are cooled down again at high speed due to the temperature difference in the workpiece. This means that the thermal distortion of the material is very low.
What are the costs for a laser welding system?
The costs for a laser welding system usually amount to around € 50.000 - € 2.000.000
What should you watch out for when laser welding?
Only metals with a low carbon content can be welded. The joining surface must be cleaned. No large temperature differences.
What speed is possible with laser welding?
Under ideal circumstances, the long, straight endless seam, welding speeds of up to 60 m / minute can be achieved.
What are the areas of application for laser welding?
Tool making, automotive industry, aircraft industry, steel construction, shipbuilding.
What other laser processes does Arnold Maschinenfabrik offer?
Laser cutting, laser deposition welding, laser polishing, laser drilling, laser cleaning and laser hardening.
WeLD-80 laser welding cell
In WeLD-80 laser welding cell builds all the components required for a series process for laser welding of rotationally symmetrical components on a minimal area of 800 x 1200 mm.
Thanks to its flexible setup, this welding cell is particularly suitable for meeting the increased requirements for complete solutions for laser welding with additional secondary processes.
WeLD-150 laser welding cell
In WeLD-150 laser welding cell forms the practical extension and expansion stage with radial welding. With the extended possibilities of a larger installation space and the possibility of axial and radial welding, this welding cell can weld almost all rotationally symmetrical components with the laser. The axial and radial welding can be carried out without retooling. An increased clamping force also enables welding of massive components such as differentials.
