The core components of a laser welding system are: A laser as the energy supplier to reach the melting point of the components to be connected, suitable clamping devices and NC-controlled machine kinematics to control the course of the laser welded connection. In our laser systems, the laser radiation is focused on a specific point with an in-house developed optic. This point is in the immediate vicinity of the abutting edge, i.e. the connection point of the components to be welded. The exact position of the focus in relation to the workpiece surface (above or below the surface) is an important parameter affecting the weld joint. The focus point in laser welding has a typical diameter of a few tenths of a millimeter. This results in very high energy concentrations in the focal point, especially since the laser power in our welding systems is several kilowatts. This results in a rapid increase in temperature at the connection point of the components to be welded, which leads to the formation of a melt. The rapid cooling of the weld seam usually results in a hard weld zone, which loses toughness depending on the material. The flexible Arnold laser welding systems from Ravensburg enable the processing of various components, e.g. Die-cast and copper components. Depending on the component size and cycle time requirements, we offer various system options. In order to guarantee optimal process quality for our customers, we integrate all common laser technologies such as fiber, disk, diode and CO2 lasers into our systems. Various optical systems are available for the welding process, including welding optics, scanners and wobble optics. We develop and deliver project-specific clamping technology and automation solutions as part of our turnkey systems.
